Description
Technical field
The utility model relates to a kind of high-efficiency air cooling source pump, belongs to field of mechanical technique.
Background technology
Conventional Air-Cooled Heat Pump Unit is divided into refrigeration, heats two kinds of operational modes, summer refrigeration, winter heating, when refrigerating operaton, compressor is discharged temperature-sensitive gases at high pressure and is entered cross valve, cross valve flows to condenser again, by condenser fan be condensed into liquid after after flow to choke valve, liquid is carried out decrease temperature and pressure by choke valve, enter evaporimeter and chilled water and carry out heat exchange (reduction water temperature), after liquid heat absorption becomes gaseous state, get back to four-way change-over valve, then flow back to compressor, complete kind of refrigeration cycle.When heating operation, cross valve commutates, high-temperature high-pressure refrigerant gas is entered in evaporimeter (now evaporimeter is when condenser function use), carry out heat exchange (lifting water temperature) with water, after refrigerant gas condensation more in the other direction by flowing to condenser (now condenser when evaporimeter use) after expansion valve throttling, in condenser, with environment temperature heat exchange, cold-producing medium flows back to compressor after returning four-way change-over valve after evaporating.Air-Cooled Heat Pump Unit is influenced by environmental temperature, and summer, while refrigeration, environment temperature was high, and the condensation effect of condenser is poor, causes the refrigerating capacity of unit to reduce, and wasted work increases, and Energy Efficiency Ratio reduces.When winter heating, environment temperature is low, condenser (when evaporimeter uses) evaporation effect is now poor again, cause the heating capacity of unit to reduce, wasted work increases, Energy Efficiency Ratio reduces, while using in the winter time simultaneously, also has a problem, fin condenser (when evaporimeter uses) is to have defrost problem, defrost is because environment temperature is when lower, condensation vapor forms frost on fin, the formation of frost can hinder heat exchange, cause heating capacity sharply to reduce, and too much affect heating capacity for fear of frost, common unit is that the form of freezing by conversion is carried out defrost, it is winter operation refrigeration mode, the hot gas of compressor is discharged to after the frost of fin outside being melted in fin condenser and is transformed into heating operation again, but when winter, defrost conversion is frequent, every defrost once all will stop heat supply, user is made a big impact, directly affect heating efficiency.
Utility model content
Utility model object: the purpose of this utility model is in order to solve above the deficiencies in the prior art, and a kind of high-efficiency air cooling source pump is provided.
Technical scheme: high-efficiency air cooling source pump described in the utility model, its objective is such realization, a kind of high-efficiency air cooling source pump, comprise refrigeration compressor, four-way change-over valve, evaporimeter, finned cooler, the import of described refrigeration compressor, outlet is connected with two interfaces of four-way change-over valve, described evaporimeter, be connected two ports of path of composition of finned cooler are connected with two other interface of cross valve, the inlet side of described finned cooler is provided with finned water cooler, the entrance of described finned water cooler is connected with evaporator outlet by pipeline, the outlet of finned water cooler is connected with evaporator inlet by pipeline.
Operation principle:
Summer is when refrigerating operaton, in order to reduce condensation temperature, the chilled water lower temperature of evaporimeter water inlet pipe is drawn to sub-fraction to fin water cooler, when operation, air is first undertaken flowing through finned cooler after precooling by finned water cooler again, manual type reduces the air themperature that flows through condenser, can strengthen condensation effect, and then promotes refrigerating capacity, reduce wasted work, overall Energy Efficiency Ratio gets a promotion simultaneously.
When winter heating moves, in order to promote evaporating temperature (fin condenser makees evaporimeter and uses), hot water is drawn partly to fin water cooler, when operation, air is first undertaken flowing through finned cooler (making evaporimeter uses) after preheating by finned water cooler again, manual type promotes the air themperature that flows through fin, can strengthen evaporation effect, lifting refrigerating capacity, overall Energy Efficiency Ratio get a promotion.Meanwhile, in the process of hot water preheating, after the air themperature that flows through fin gets a promotion, fin can frosting, has solved again and has heated the problem that needs to change defrost in process, has promoted heating efficiency.
Beneficial effect: when common Air-Cooled Heat Pump Unit refrigeration, when environment temperature is high, refrigerating efficiency is poor, when high-efficiency air cooling source pump refrigeration, although lose a part of cold water (part refrigerating capacity), but the refrigerating capacity that lifting condensation efficiency obtains will be much larger than loss, experiment records, and the utility model can promote 10-15% refrigerating capacity, power-dissipation-reduced 7-8%.
When common Air-Cooled Heat Pump Unit heats, when environment temperature is low, heating efficiency is poor, when high-efficiency air cooling source pump heats, although lose a part of hot water (part heating capacity), promoting the heating capacity that evaporation efficiency obtains will be much larger than loss, the utility model has been avoided the process of conversion defrost, making in situation that unit moves in the winter time can uninterrupted heat supply, and heating efficiency gets a promotion, and experiment is surveyed, heating capacity can promote 25%, and power consumption can reduce by 13%.
Accompanying drawing explanation
Fig. 1 is the structural representation of general Air-Cooled Heat Pump Unit in prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
Shown in Figure 2, a kind of high-efficiency air cooling source pump, comprise refrigeration compressor 1, four-way change-over valve 2, evaporimeter 3, finned cooler 4, the import of described refrigeration compressor 1, outlet is connected with two interfaces of four-way change-over valve 2, described evaporimeter 3, be connected two ports of path of composition of finned cooler 4 are connected with two other interface of cross valve 2, the inlet side of described finned cooler 4 is provided with finned water cooler 5, the entrance of described finned water cooler 5 is connected with evaporimeter 3 outlets by pipeline, the outlet of finned water cooler 5 is connected with evaporimeter 3 entrances by pipeline.
