Description
Technical field
The utility model relates to special-purpose double evaporators cold water (heat pump) unit of a kind of ice-reserving, belongs to the air conditioner refrigerating technology.
Background technology
Because traditional duplexing condition refrigeration unit structurally has only an evaporimeter, ice-reserving and cooling adopt same evaporimeter, to adopt a secondary heat exchange device when therefore between two operating modes, switching, because there is loss of refrigeration capacity in the secondary heat exchange process, make the efficient of system reduce greatly, and there is the pipeline switching problem, the control system complexity.
Summary of the invention
The purpose of this utility model is intended to improve the weak point of prior art, provide a kind of ice-reserving special-purpose double evaporators cold water (heat pump) unit, save traditional secondary heat exchange system, can improve the efficient of system greatly, avoid the complicated pipelines handover operation, simplify the control logic of system.
The technical solution of the utility model is, special-purpose double evaporators cold water (heat pump) unit of a kind of ice-reserving, it has compressor, the condenser that connects by pipeline, characteristics are, it is provided with ice-reserving evaporimeter and refrigerating evaporator, the ice-reserving evaporimeter connects to form ice-reserving heat-exchange system loop by pipeline and compressor, condenser, and refrigerating evaporator connects to form refrigeration heat-exchange system loop by pipeline and compressor, condenser.
The utility model compared with prior art, its outstanding characteristics are that unit has adopted double evaporators, ice-reserving and refrigeration employing heat-exchange system separately, main frame can directly connect air-conditioner water system when therefore freezing, cancelled the secondary heat exchange system, the cold that main frame provides is directly supplied with the user, and the heat exchange in the middle of not existing is lost, thereby improves the heat exchange efficiency of system greatly; The second, avoided the complicated reduction of switching the refrigerant solution concentration that causes of pipeline, simplify the control logic of system, save operating cost, reduce production costs.
Below in conjunction with drawings and Examples the utility model is at length explained.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The explanation of accompanying drawing drawing:
1 compressor, 2 condensers, 3-1 ice-reserving evaporimeter, 3-2 refrigerating evaporator, 4 ice storage units, 5 coolant pump, 6 user's end equipments, 7-1 choke valve, 7-2 choke valve, 8 air-conditioning water pumps.
The specific embodiment
Referring to accompanying drawing, the utility model unit has two evaporimeters: ice-reserving evaporimeter 3-1 and refrigerating evaporator 3-2, ice-reserving evaporimeter 3-1 connects to form ice-reserving heat-exchange system loop by pipeline and choke valve 7-1, condenser 2, compressor 1, and refrigerating evaporator 3-2 connects to form refrigeration heat-exchange system loop by another pipeline and choke valve 7-2, condenser 2, compressor 1.
Operation principle: one, ice-reserving operating mode: extraneous cooling water enters from condenser 2, drive condenser 2, ice-reserving evaporimeter 3-1 operation by compressor 1, carry out the cold exchange, finish the ice-reserving operating mode by the ice storage unit 4 that is connected with ice-reserving evaporimeter 3-1, the ice-reserving loop that coolant pump 5 is formed; Two, cooling condition: extraneous cooling water enters from condenser 2, drive condenser 2, refrigerating evaporator 3-2 operation by compressor 1, carry out cold exchange, finish cooling condition by the air-conditioning water pump 8 that is connected with refrigerating evaporator 3-2 and the cooling loop of user's end equipment 6 compositions; Ice-reserving and refrigeration adopt heat-exchange system separately, do not need Intermediate Heat Exchanger to carry out pipeline between the two and switch, and have avoided the heat exchange loss, and its effect is as follows:
One, save the unit operation expense, improve the air-conditioner host ability to work simultaneously:
Because saved middle secondary heat exchange system, so can improve evaporating temperature (during refrigerating operaton), reduce condensation temperature (during heating operation), improve the unit operation condition.With certain model unit is example, and the variation of evaporating temperature sees Table one (as a reference value 100%, data are relative value in the table with standard condition refrigerating capacity, power consumption, Energy Efficiency Ratio) to the influence of unit parameter and efficient:
Table one evaporating temperature is to unit performance parameter influence (heating operation, seawater is as thermal source)
| Improve the number of degrees of evaporating temperature | 2℃ | 3℃ | 4℃ | 5℃ | 6℃ |
| Heating capacity | 106％ | 109％ | 112％ | 116％ | 119％ |
| The unit power consumption | 102％ | 103％ | 104％ | 105％ | 106％ |
| Energy Efficiency Ratio (COP) | 1.04 | 1.06 | 1.08 | 1.10 | 1.12 |
In engineering application, directly evaporation/condensation can improve evaporating temperature 3～5 ℃ than secondary heat exchange, and condensation temperature is carried low 3～5 ℃.Therefore, can reduce about 10% of unit operation expense.Simultaneously, do not have the secondary cycle water pump, the power consumption of secondary cycle water pump accounts for 10% of unit power consumption.So, the integrated operation cost of system can be reduced 20%.
Two, traditional middle secondary heat exchange system comprises plate type heat exchanger, water circulating pump, pipeline, valve, circulation fluid of secondary heat exchange etc., the equipment early investment is a lot, after using the utility model unit, not only can improve the cooling and warming ability of unit, and saved middle secondary heat exchange system, the initial stage of minimizing equipment drops into, and reduces production costs.
