Description

Heat exchanger with fluid distributor and air conditioning system using same {HEAT EXCHANGER HAVING FLUID DISTRIBUTOR, AND AIR CONDITIONING SYSTEM USING THE SAME}

The present invention relates to a heat exchanger and an air conditioning system using the same, and more particularly, a supply of a heat exchange medium flowing into an internal flow path of a heat exchange panel and a supply of liquid flowing to a surface of the heat exchange panel through a distributor provided in the heat exchanger itself. The present invention relates to a heat exchanger having a fluid distributor capable of simplifying the structure, miniaturization and weight reduction, and reducing manufacturing costs, and an air conditioning system using the same.

Generally, a heat exchanger has an internal flow path divided from the outside, and the first fluid or the second fluid is heated by the movement of heat between the first fluid flowing through the internal flow path and the second fluid flowing in contact with the outside of the heat exchanger And is used for various purposes such as cooling and heating of buildings, cooling and heating of facilities and devices, and the like. Conventional heat exchangers include a structure in which pipes are arranged or bent in a multi-row structure, a pipe structure in which a flow path is formed, and the like. Elements for increasing heat exchange area such as cooling fins may be provided on the outside.

When the second fluid outside the heat exchanger is a liquid, the second fluid may flow down along the surface of the heat exchanger to cause heat exchange between the first fluid and the second fluid. In this case, the flow of the second fluid must be distributed over the entire surface of the heat exchanger so as to be efficiently dispersed and flowed. In this case, the heat exchanger of a tubular structure is not suitable for such flow, .

The heat exchanger having a panel structure typically has a structure in which a plurality of heat exchange panels having a flow path through which a first fluid flows are arranged in parallel to be spaced apart from each other by a predetermined interval. Such a heat exchanger requires a means for circulating and supplying the first fluid to the flow path inside the heat exchange panel and a means for circulating and supplying the second fluid to flow along the outer surface of the heat exchange panel. In addition, there is a need for a means for distributing and supplying the second fluid such that the second fluid flows along the surface of the heat exchange panel in a uniformly spread flow.

However, since the conventional panel structure heat exchanger does not have an efficient structure for supplying the first and second fluids described above, the heat exchanger requires complicated piping and a connection for connecting the heat source and the heat source of each fluid. Since the air itself and the surrounding structure are complicated, the second fluid is not uniformly supplied to the surface of the heat exchange panel, thereby reducing the heat exchange efficiency.

On the other hand, the operation of the dehumidifying cooling cycle using a liquid dehumidifying agent (hereinafter referred to as a dehumidifying liquid) dehumidifies the air while sucking the steam from the ambient air at a low temperature and diluting the dehumidified liquid at a low concentration, By the physical properties of. The exchange of water vapor between the air and the dehumidifying liquid depends on the relative amount of steam partial pressure in the air and the vapor pressure on the surface of the dehumidifying liquid in contact with the air. The steam pressure on the surface of the dehumidifying liquid is a function of the temperature and concentration of the dehumidifying liquid. That is, dehumidification of the humidifier is performed through the absorption process at a low temperature depending on the steam pressure difference between the dehumidified liquid and the air at a given steam pressure, and the dehumidification of the dehumidified liquid through desorption at a high temperature regeneration.

In the absorption process, not only the condensation heat due to the condensation of steam on the surface of the dehumidifying liquid but also the heat of absorption due to the mixed heat is always generated. Therefore, in order to improve the dehumidifying ability, it is necessary to cool the dehumidifying liquid. On the other hand, in the dehydration process of the dehumidifying agent, that is, in the regeneration process, heat input is required to evaporate the water absorbed in the dehumidifying liquid to a concentration suitable for reuse.

1 illustrates a liquid-type dehumidification air conditioning system of a conventional packing tower type, in which a dehumidifier is dehumidified of air and a regenerator is regenerated. In the dehumidifier, the hot / humid air 1 is in direct contact with the dehumidifying liquid 2 flowing in the porous filler inside the dehumidifier during the dehumidification process in which the dehumidifying liquid absorbs water vapor in the air. Water vapor in the air is condensed / absorbed on the surface of the dehumidification liquid, and this dehumidification process is an adiabatic process with a constant enthalpy. At this time, the temperature of the air is slightly increased and the absolute humidity is decreased. Process air (3) dried through the dehumidification process is cooled while passing through the evaporative cooler (4) is made of air (5) of the desired temperature and humidity.

While the dried process air 3 passes through the evaporative cooler 4, the temperature of the air is lowered, and the absolute humidity is also slightly lower than the original state. The ability of the dehumidifying solution to absorb water vapor decreases with increasing water content, and dehumidifying solutions containing more than a certain amount of water can be used again in the dehumidification process only after being regenerated through a regeneration cycle. Therefore, the dehumidifying solution dilute solution 6 which absorbs moisture in the air in the dehumidifier and is diluted is sent to the regenerator. The dehumidifying solution of the regenerator is passed through the solution heater 11 to facilitate the absorption of moisture absorbed into the regenerated air. The dehumidifying liquid heated in the solution heater (11) is distributed in the solution distributor (10) and discharges the moisture in the dehumidifying solution to the regeneration air while contacting the regeneration air (8) in the regenerator to be converted into a concentrated solution (7). The regenerated air 9 which absorbed moisture is discharged to the outside. In addition, the dehumidifying liquid from which the moisture is removed from the regenerator is passed through the solution cooler 12 so as to perform effective dehumidification before being supplied to the dehumidifier. The moisture absorption capacity of the dehumidifying liquid used in the liquid dehumidification air conditioning system is closely related to the temperature as well as the concentration. If the temperature is high, the steam partial pressure is increased to facilitate regeneration. If the temperature is low, the steam partial pressure is lowered to facilitate dehumidification. Because of this characteristic, the design is designed to pass through the solution cooler 12 during dehumidification and to pass through the solution heater 11 during regeneration.

However, as described above, the conventional dehumidifier and the regenerator have a structure in which the dehumidifying liquid flows along the filler provided therein while contacting the air to dehumidify the air or regenerate the dehumidifying liquid, that is, while passing through the filling material. In the dehumidifier, the dehumidifier absorbs heat from the air as it passes through the filler and fails to maintain the desired low temperature. In the regenerator, the dehumidifier passes through the filler. The heat is released to the air, which prevents it from maintaining the desired high temperature. Accordingly, conventionally, there is a problem in that the dehumidification efficiency of the dehumidifier and the regeneration efficiency of the regenerator are inferior.

In order to solve this problem, it is required to apply a heat exchanger that cools or heats the dehumidifying liquid while flowing the dehumidifying liquid in contact with the air to the dehumidifier and the regenerator.

The heat medium storage tank 302 is connected to the heat exchanger 134 of the regenerator 130 through the first heat medium circulation pipe 102, and of the heat pump part 200 through the second heat medium circulation pipe 128. It is connected to the evaporator 204 and circulates a heating medium, for example, hot water, to the heat exchanger 134 or the evaporator 204 according to the operating state.

The cooling tower 400 is connected to the heat exchanger 114 of the dehumidifier 110 through the cooling medium circulation pipe 101 to circulate and supply the cooled cooling medium, for example, cooling water.

The air conditioning system configured as described above is selectively operated in a cooling operation mode for supplying cooled air to a predetermined application and a heating operation mode for supplying heated air. In the following description, a case where water is used as a heat medium and a cooling medium will be described.

First, the operation of the cooling operation mode shown in FIG.

In the cooling operation mode, the dehumidifier 110 dehumidifies the air by the dehumidifying liquid, and the regenerator 130 performs the regeneration of the dehumidifying liquid by heating.

That is, the dehumidifying liquid transferred through the solution heat exchanger 140 is supplied to the upper distributor 113 of the heat exchanger 114 installed in the dehumidifier 110, and the liquid containing chamber 33 of the upper distributor 113. The dehumidifying solution contained in the flows out through the outlet 34 and flows down along the surface of each heat exchange panel 115. In addition, air containing a large amount of moisture is introduced through the intake pipe 117 of the dehumidifier main body 111 to move between the heat exchange panel 115 in a horizontal direction.

Accordingly, the moisture contained in the air is absorbed by the dehumidifying liquid while the dehumidifying liquid is in contact with the air, and the dehumidified air is supplied to the solvent through the air supply pipe 112. At this time, the air supply valve 124 blocks the connection pipe so that dehumidified air does not flow to the exhaust pipe 132 side.

At the same time, cooling water is supplied from the cooling tower 400 to the heat exchanger 114 of the dehumidifier 110 to cool the dehumidifying liquid on the surface of the heat exchange panel 115. As a result, the temperature of the dehumidifying liquid is kept at a low temperature to achieve more efficient dehumidification. In addition, the coolant 121 is supplied with cooling water from the evaporator 204 and cooled to a required temperature.

The dehumidifying liquid that absorbs a large amount of water while passing through the heat exchanger 114 of the dehumidifier 110 is accommodated in the collection tank 116 and then transferred to the regenerator 130 through the solution heat exchanger 140. The transferred dehumidifying liquid is supplied to the upper distributor 133 of the heat exchanger 134 installed in the regenerator 130, and the dehumidifying liquid flowing out through the outlet 34 is exchanged to the heat exchange panel 135 of the heat exchanger 134. Flow down along. At the same time, outside air introduced through the intake pipe of the regenerator body 131 is moved through the heat exchanger 134. In addition, the hot water stored in the heat medium storage tank 302 of the solar heat storage unit 300 is supplied to the heat exchanger 134 of the regenerator 130 to heat the dehumidifying liquid.

Accordingly, the dehumidifying liquid is more efficiently regenerated, and the regenerated dehumidifying liquid is received in the collection tank 136 of the regenerator 130 and then supplied again to the dehumidifier 110 through the solution heat exchanger 140. . Air absorbing moisture is discharged to the outside through the exhaust pipe (132). In addition, the hot water is supplied to the first radiator 122 from the condenser 202 and the air introduced into the regenerator 130 is heated in advance, thereby regenerating the dehumidifying liquid more effectively.

Next, the operation of the heating operation mode shown in FIG. 8 will be described.

As shown, the hot water stored in the heat medium storage tank 302 of the solar heat storage unit 300 is supplied to the evaporator 204 side through the second heat medium circulation tube 128. Heat of the hot water is absorbed by the refrigerant circulating through the heat pump unit 200 through the evaporator 204, and the heat absorbed by the refrigerant is discharged through the condenser 202 to the hot water flowing through the heat medium tube 127. By the second heat radiator 126.

Accordingly, the air supplied to the solution through the air supply pipe 112 is heated by the second radiator 126 to thereby heat the solution. In this case, the exhaust pipe 132 may be connected to the outside or may be connected to the solvent. Depending on the connection of the exhaust pipe 132, the outside air may be heated and supplied to the solution, or may be heated and supplied while circulating the air of the solution.

Although not shown, dehumidification may be performed by the operation of the dehumidifier 110 and the regenerator 130 even in a heating operation mode. For example, the second radiator 126 may be installed in the air supply pipe 112 to heat the air dehumidified by the dehumidifier 110.

The air conditioning system as described above supplies heat medium for regenerating the dehumidifying liquid of the regenerator 130 using solar heat, which is clean energy, as a heat source, so that energy cost required for operating the system can be reduced and pollution can be prevented. do.

In addition, while absorbing heat through the evaporator 204 of the heat pump to supply the cooled air to the solvent, the dry bulb temperature of the air supplied to the regenerator 130 by using the heat generated from the condenser 202 of the heat pump Increase the efficiency of the regenerator to increase the energy efficiency by reusing the energy discarded during the heat pump operation.

In addition, the heat exchanger 10 installed in the dehumidifier 110 and the regenerator 130 is provided with a medium chamber 31 in the upper distributor 30 and the lower exhaust 40 coupled to the heat exchange panel 20. In addition, since the cooling medium or the heating medium is configured to be supplied through the medium storage chamber 31, the structure may be simplified since no separate means for connection with an external cooling medium source or the heating medium source is required.

In particular, the liquid storage chamber 33 is provided inside the upper distributor 30, and the dehumidifying liquid contained in the liquid storage chamber 33 flows out through the outlet 34 and flows along the heat exchange panel 20. Since it is made of a structure that is supplied to lower, it does not need a separate means for supplying a dehumidifying liquid to the heat exchanger 10 as in the prior art has the advantage that the structure is further simplified.

In addition, since the heat dissipation part 23 is provided in the heat exchange panel 20, the dehumidifying liquid flowing out of the upper distributor 30 forms a wide and evenly distributed flow on the surface of the heat exchange panel 20. Moisture exchange between the dehumidifying liquid is promoted, and heat exchange between the dehumidifying liquid and the cooling medium or the heat medium is also promoted, so that dehumidification and regeneration efficiency are further improved.
