Below in conjunction with accompanying drawing, the course of work and the operation principle of the air-condition heat exchanger provided with regard to the utility model embodiment are described.
As shown in Figure 1 to Figure 3, when air conditioner refrigerating, the condensed liquid refrigerants of device 4 that is condensed enters from the input pipe 12 of described air-condition heat exchanger 1, each shunting capillary 15 is dispensed to through distributor 14, in the shunting capillary 51 being provided with check valve 13, refrigerant is along the direction flowing that the valve 32 of check valve 13 is opened and enter into shunting capillary 51 by check valve 13, in other shunting capillaries 15 that check valve 13 is not set, refrigerant flows and enters into these shunting capillaries, and then the heat exchanger tube 16 through being connected with each shunting capillary, carburation by evaporation absorbs heat, become the refrigerant of gaseous state low temperature, and absorb heat to room air, realize refrigeration, then the described efferent duct 11 of refrigerant through collecting each heat exchanger tube 16 of gaseous state collects output,
When air-conditioning heating, the flow direction of refrigerant is contrary with the flow direction of refrigerant during air conditioner refrigerating, gaseous coolant after being compressed by compressor 2 enters from the efferent duct 11 of described air-condition heat exchanger 1, heat exchanger tubes 16 through being connected with each shunting capillary phase 15 carry out heat exchange, in the shunting capillary 51 being provided with check valve 13, the direction flowing that refrigerant is opened against the valve 32 of check valve 13, valve 32 is closed, the flowing of refrigerant end by check valve 13, loop containing this check valve can not realize heat exchange, in other shunting capillaries 15 that check valve 13 is not set, refrigerant flows and enters into these shunting capillaries, heat exchange can be realized, the refrigerant of gaseous state is through heat exchanger condensation liquefaction, become liquid refrigerant, and to room air release heat, realization heats effect, then liquid refrigerant is pooled to described input pipe 12 through distributor 14 and exports.
Compared with the air-conditioning of traditional design, check valve allows refrigerant to pass through when air conditioner refrigerating, ensures that heat exchange area is constant, meets the requirement of high energy efficiency during refrigeration; Can stop or allow refrigerant to pass through when air-conditioning heating, the quantity of the heat exchanger tube that refrigerant is passed through reduces, improve the coolant quantity in air quantity general goal heat exchanger tube, thus the heat exchange amount improved in the unit interval, leaving air temp is improved, meet the requirement of human comfort, solve existing air-conditioner refrigeration require high energy efficiency while occur heat the lower problem of leaving air temp.
The air-condition heat exchanger that the utility model embodiment provides, can not only improve leaving air temp when heating, and can also keep high energy efficiency when freezing.To the air-condition heat exchanger being provided with check valve designed according to the utility model embodiment, with the air-condition heat exchanger not arranging check valve of traditional design, carry out Experimental Comparison with regard to heating capacity, leaving air temp and refrigerating capacity aspect, comparing result is as shown in table 1:
The contrast of table 1 heating capacity, leaving air temp and refrigerating capacity
? Heating capacity (W) Leaving air temp (DEG C) Refrigerating capacity (W)
Existing air-condition heat exchanger 8831 34.42 8725
The utility model air-condition heat exchanger 9004 35.65 8730
Lifting capacity 173 1.23 Quite
Promote percentage 1.95% 3.5% Quite
As can be seen from Table 1, be provided with the air-condition heat exchanger of check valve than the air-condition heat exchanger not arranging check valve, heating capacity improves 173W, and promoting percentage is 1.95%; Leaving air temp improves 1.23 DEG C, and promoting percentage is 3.5%; Refrigerating capacity is substantially suitable.When heating, the raising of heating capacity and leaving air temp is mainly because the air quantity bottom air-condition heat exchanger is less, the exchange capability of heat of the heat exchanger tube causing the shunting capillary of evaporimeter bottom to connect is poor, cause that the heat transfer rate of refrigerant is comparatively slow, heat exchange is insufficient, heating capacity loses, by the cut-off effect of check valve to refrigerant in above-mentioned shunting capillary, effectively refrigerant is concentrated and be in the large heat exchanger tube of air quantity, facilitate the increase of refrigerant heat transfer rate, the increase of heat exchange amount in unit interval, thus the heating capacity that improve when heating and leaving air temp.During refrigeration, check valve is the state opened, and can ensure refrigerant smoothly by each shunting capillary, compared with traditional air-conditioner not arranging check valve, substantially do not have difference, therefore refrigerating capacity does not have difference substantially yet.
As shown in Figure 4 and Figure 5, the utility model embodiment on the other hand provides a kind of air conditioner heat exchange system, comprise: the evaporimeter 1 of compressor 2, indoor, the condenser 4 of outside, connect the four-way change-over valve 3 of described compressor 2 and evaporimeter 1 and condenser 4 and the throttle capillary tube 5 between evaporimeter 1 and condenser 4, described evaporimeter is the air-condition heat exchanger 1 described in above-mentioned any embodiment.
The air conditioner heat exchange system that the utility model embodiment provides, comprises the air-condition heat exchanger described in above-mentioned any embodiment, can realize the refrigeration of air-conditioning and heat effect, and when can ensure refrigeration well while high energy efficiency, improves leaving air temp when heating.When air conditioner heat exchange system carries out refrigeration work, first the refrigerant of gaseous state passes through compressor, be compressed to the gaseous coolant of HTHP, compressor is connected with condenser by four-way change-over valve, then the condenser of outside is delivered to, condensation liquefaction heat release, become the liquid refrigerants of normal temperature high voltage, heat discharges to outside atmosphere simultaneously, then reduce pressure through throttle capillary tube, enter the evaporimeter of indoor, liquid refrigerant carries out heat exchange through evaporimeter, carburation by evaporation absorbs heat, become the refrigerant of gaseous state low temperature, absorb a large amount of heats to room air simultaneously, evaporimeter turns cold, the air of indoor is blown over by indoor fan from evaporimeter, room air is turned cold, then the refrigerant of gaseous state, again enter compressor, start next circulation, realize air cycle refrigeration.When air conditioner heat exchange system carries out heating work, by connecting the commutation effect of the four-way change-over valve of compressor and evaporimeter and condenser, contrary when making the flow direction of refrigerant in condenser and evaporimeter and freeze, now condenser plays evaporation, evaporimeter plays condensation, thus realizes heating of room air.
Preferably, described check valve 13 is arranged on described evaporimeter 1 bottom and crosses on the minimum shunting capillary 51 of air quantity.During owing to heating, the air quantity of described base of evaporator is less, the exchange capability of heat of the heat exchanger tube causing the shunting capillary of evaporimeter bottom to connect is poor, cause that the heat transfer rate of refrigerant is comparatively slow, heat exchange is insufficient, heating capacity loses, and by the cut-off effect of check valve to refrigerant in this shunting capillary, effectively promotes refrigerant and concentrates and be in air quantity is large and heat transfer rate is fast heat exchanger tube, the increase of heat exchange amount in unit interval, thus improve leaving air temp when heating.
