Description
Technical field
The utility model relates to a kind of air energy heat pump.
Background technology
Air energy heat pump as the term suggests utilize the energy in air to produce heat energy exactly, can 24 hours big yields of whole day,
High hydraulic pressure, constant temperature provide the whole family different hot water demand, can consume again the water heater that the minimum energy completes above-mentioned requirements simultaneously.
And be in while efficiently produce domestic hot-water, can as air-conditioning releasing cool air, meet the refrigeration demand in kitchen, and can
With between balcony, storing, the local space such as garage reaches the effect of dehumidifying and prevents article moldy metamorphism or rapid airing clothing.
Air energy heat pump is generally made up of evaporimeter, compressor, condenser and expansion valve.
Compressor enables air to the heart of heat pump, and low-pressure gas can be promoted to a kind of driven fluid of gases at high pressure by it
Machinery.In order to ensure the safe handling of compressor, prevent liquid hit phenomenon, it is desirable to suction temperature is higher than evaporating temperature,
I.e. should have certain degree of superheat.
Strengthen the mode of evaporimeter when currently mainly using design, which not only adds the cost of evaporimeter, Er Qiezeng
The big volume of main frame.
Utility model content
The purpose of this utility model is to provide a kind of air energy heat pump that can improve the compressor return air degree of superheat, to reduce
The cost of evaporimeter, reduces main frame volume.
The utility model discloses a kind of air energy heat pump, including evaporimeter, compressor, condenser, electric expansion valve and
Economizer.The housing two ends of economizer connect with described condenser and electric expansion valve respectively, the heat exchange coil two in economizer
End connects with described evaporimeter and compressor respectively, makes in gaseous refrigerant and the economizer of low-temp low-pressure after evaporation in evaporimeter
The liquid refrigerant heat exchange of HTHP before throttling enters back in compressor after heating up, and improves the degree of superheat of compressor return air.Separately
Outward, moreover it is possible to increasing the degree of supercooling before coolant throttle, so in the case of identical power consumption, efficiency is higher.
Gaseous refrigerant after described evaporator evaporation enters from the nearly liquid refrigerant inlet end of described economizer through pipeline
Enter in the heat exchanger tube in economizer, become through heat exchange flowing out through pipe from the nearly liquid condensation device port of export of economizer after overheated gas
Road enters in compressor.
In order to the high-low pressure balance making heat pump is more preferable, this heat pump also includes cross valve, two interfaces of cross valve
For connecting the pipe for flowing of refrigerant road between described condenser and compressor, two other interface is used for connecting compressor and steaming
Send out the pipe for flowing of refrigerant road between device.
The liquid refrigerant of low-temp low-pressure becomes the gaseous refrigerant of low-temp low-pressure after evaporator evaporation, through economy
Become overheated gas after the liquid refrigerant heat exchange of the HTHP before device and throttling, then become HTHP through compressor compression
Gaseous refrigerant, after condenser heat exchange, become the liquid refrigerant of HTHP, be then passed through economizer and compressor
Return-air heat exchange, becomes the liquid refrigerant of low-temp low-pressure, thus completes a circulation after eventually passing expansion valve.
The gaseous refrigerant utilizing the low-temp low-pressure before liquid refrigerant and the return-air of the HTHP before throttling changes
Heat, reaches to increase the purpose of the return-air degree of superheat.Overcome cost increase and the master that prior art is brought by strengthening evaporimeter
Body amasss the defect of increase, under the effect ensureing the compressor return air degree of superheat, reduces the cost of evaporimeter, reduces main frame
Volume.
Brief description
Fig. 1 is system catenation principle figure of the present utility model.
Detailed description of the invention
As it is shown in figure 1, present embodiment discloses a kind of air energy heat pump, including evaporimeter the 1st, compressor the 2nd, condenser the 3rd, electricity
Sub-expansion valve the 4th, economizer the 5th, cross valve 6.
The housing two ends of economizer 5 connect with condenser 3 and electric expansion valve 4 respectively, the heat exchange coil two in economizer 5
End connects with evaporimeter 1 and compressor 2 respectively.
Gaseous refrigerant after evaporimeter 1 evaporation enters economy through pipeline from the nearly liquid refrigerant inlet end of economizer 5
In heat exchanger tube in device 5, become through heat exchange flowing out to enter through pipeline from the nearly liquid condensation device port of export of economizer 5 after overheated gas
Enter in compressor 2.
Two interfaces of cross valve 6 for connecting pipe for flowing of refrigerant road between condenser 3 and compressor 2, other two
Individual interface is for connecting the pipe for flowing of refrigerant road between compressor 2 and condenser 3.
The operation principle of the present embodiment is as follows: it is low that the liquid refrigerant of low-temp low-pressure becomes low temperature after evaporator evaporation
The gaseous refrigerant of pressure, becomes overheated gas after the liquid refrigerant heat exchange of the HTHP before economizer with throttling, then
Become the gaseous refrigerant of HTHP through compressor compression, after condenser heat exchange, become the liquid refrigerating of HTHP
Agent, is then passed through economizer and compressor return air heat exchange, becomes the liquid refrigerant of low-temp low-pressure after eventually passing expansion valve, from
And complete a circulation.The gaseous refrigerant of the low-temp low-pressure before the liquid refrigerant of the HTHP before utilization throttling and return-air
Carry out heat exchange, reach to increase the purpose of the return-air degree of superheat.Overcome the cost increasing that prior art is brought by strengthening evaporimeter
Add the defect increasing with main frame volume, under the effect ensureing the compressor return air degree of superheat, reduce the cost of evaporimeter, reduce
The volume of main frame.In addition, the degree of supercooling before coolant throttle can also be increased, so in the case of identical power consumption, efficiency is higher.
