Description

Multifunctional Finned Tube Condenser

Technical field:

The utility model relates to a multifunctional finned tube condenser with the functions of precooling air and producing domestic hot water, which is suitable for the refrigeration field of household air conditioners.

Background technique:

In recent years, domestic air conditioners have rapidly and widely entered Chinese families, and their popularity has surpassed that of many developed countries. At present, most domestic air-conditioning condensers use finned tube air-cooled condensers. The refrigerant flows in the tube and releases heat, and the air flows between the fins outside the tube and absorbs the heat released by the refrigerant. Through the cold and heat exchange between the refrigerant and the air , to achieve cooling in summer. However, the survey of its use shows that in summer when air conditioners are frequently used, the outdoor air temperature is generally high, which makes the air conditioner often deviate from the rated working condition, which directly leads to a high condensation temperature of the air conditioning system and a decrease in the cooling coefficient. In addition, the traditional household air conditioner condenser directly discharges the condensation heat into the atmosphere, which causes waste of heat and brings thermal pollution to the environment.

Invention content:

In order to solve the problem that the cooling efficiency of the existing air conditioner decreases and the condensation heat cannot be recovered when the outdoor temperature is too high in the hot season, the utility model proposes a multi-functional finned tube condenser, which can significantly improve The cooling efficiency of the air conditioner can also be used to make domestic hot water by using the heat of condensation.

The technical scheme adopted by the utility model to solve the technical problem is: including the heat exchange pipe of the fin tube condenser, the fins installed on the heat exchange pipe of the fin tube condenser, and the heat exchange pipe of the fin tube condenser With the shell of fins and the fan installed on the shell, the heat exchange pipe of the fin tube condenser is divided into two parts, one part of the pipe is the water pipe, the other part of the pipe is the refrigerant pipe, and the air path on both sides of the refrigerant pipe The above are water pipes respectively.

The shape of the finned tube condenser heat exchange pipe is round or oval or square or triangular; the fins are flat fins or slotted fins or flat rectangular louvers or corrugated arc louvers.

The water pipe of the heat exchange pipe of the finned tube condenser is connected with the water tank.

The beneficial effect of the utility model is: when cooling in summer, the temperature of the air can be lowered first, and then the condensation temperature of the air conditioner in summer can be lowered, and the refrigeration coefficient can be finally improved. thermal pollution. The equipment is simple in structure and easy to control.

Detailed ways:

As shown in Figures 1 and 2, the utility model includes a fin tube condenser heat exchange pipe 1, a fin 2 installed on the fin tube condenser heat exchange pipe 1, a fin tube condenser heat exchange The shell 3 of the pipe 1 and the fin 2, the fan 4 installed on the shell 3, the heat exchange pipe 1 of the finned tube condenser is divided into two parts, one part of the pipe is the water pipe 6, and the other part of the pipe is the refrigerant pipe 5, The air paths on both sides of the refrigerant pipeline 5 are respectively water pipelines 6 . 9 is the inlet of the water pipeline 6 , and 10 is the outlet of the water pipeline 6 . 7 is the refrigerant inlet of the refrigerant pipeline 5 , and 8 is the refrigerant outlet of the refrigerant pipeline 5 .

The shape of the finned tube condenser heat exchange pipe is round or oval or square or triangular; the fins are flat fins or slotted fins or flat rectangular louvers or corrugated arc louvers. The water pipe of the heat exchange pipe of the finned tube condenser is connected with the water tank.

A finned tube condenser with a structure of tubes and fins is adopted. The components of the condenser include fins, tubes, fans and shells. The heat exchange pipe is divided into two parts, one of which contains water, and the other part contains refrigerant, and the air flows outside the pipe, and the fins are used to enhance the heat transfer coefficient of the air side. When the condenser is running in summer, the outdoor air first passes through the water-filled pipes, exchanges heat and cold with the water in the pipes, and lowers the air temperature, and then the cooled air exchanges heat with the refrigerant pipes behind, taking away the refrigerant The heat, and finally the high-temperature air passes over the water-filled pipes again to heat the water to produce domestic hot water.

The parts of the utility model in Fig. 1 include fins, ducts, fans and casings. Water flows in some pipes of the condenser, refrigerant flows in the remaining pipes of the condenser, and air flows between the fins outside the pipes, and the fins are used to enhance the heat transfer coefficient of the air side. Figure 2 mainly shows the flow mode of the heat exchange medium in the condenser. The air first passes through the pipes filled with water to be cooled, then passes through the pipes filled with refrigerant, exchanges heat with the refrigerant and is heated again, and finally the high-temperature air Once again it passes through the water-filled pipes and is cooled again. At the same time, the water in the pipe is heated and can be used as domestic hot water.

In Figure 1, water flows in part of the pipes of the condenser, refrigerant flows in the rest of the pipes of the condenser, and air flows between the fins outside the pipes, while the pipes of the traditional finned tube condenser are all refrigerated agent. According to the outdoor temperature, by controlling the start and stop of the fan and the water pump, the heat exchange between the air and the refrigerant alone or the heat exchange between the air and the refrigerant can be realized successively. When the air conditioner is running in summer, the water pump is turned on. The air first exchanges heat with the water in the pipe, then exchanges heat with the refrigerant in the finned tube heat exchanger after cooling down, and finally exchanges heat with the water in the pipe to recover the condensation heat and heat the living room. For hot water, the indoor evaporator exchanges heat with the air in the room and supplies cooling to the room. At this time, the air conditioner realizes cooling and heating at the same time. In winter, the air conditioner is used as a heat pump. Depending on the weather conditions, it is determined whether to pass hot water in the pipeline. When the hot water is passed, the evaporation temperature of the system can be increased.
