Abstract
The utility model relates to an air conditioning system with a heat recovery function. The air conditioning system mainly comprises a compressor (1), an outdoor heat exchanger (2), an indoor heat exchanger (3), a warmth-keeping water tank (4) and a solenoid valve (5), wherein the solenoid valve and the warmth-keeping water tank are connected in parallel in a pipeline between the outdoor heat exchanger and the compressor. By disconnecting the warmth-keeping water tank from the system or connecting the warmth-keeping water tank with the system through the control of the solenoid valve, not only can the water temperature be accurately controlled and the potential safety hazard of too high pressure of the warmth-keeping water tank be precluded, but also the air conditioning system can be used for heat-pump air conditioners for refrigeration and heating.
Description
Technical field
The utility model relates to a kind of air-conditioning system with heat recovery function, belongs to filed of air conditioning.
Background technology
As shown in Figure 1, existing air-conditioning system with heat recovery function is mainly by 4 one-tenth, compressor 1, outdoor heat exchanger 2, indoor heat exchanger 3, attemperater group.Wherein, attemperater 4 is connected on pipeline between outdoor heat exchanger 2 and compressor 1.When air conditioner refrigerating moved, cold-producing medium moved towards as shown by arrows in FIG., during the cold-producing medium of HTHP process attemperater 4, water was heated, realizes the air-conditioning system heat recovery function.
Yet, in this air-conditioning system with heat recovery function, because attemperater 4 is connected in system, cold-producing medium 2 must carry out heat exchange through attemperater 4 when flowing from compressor 1 to outdoor heat exchanger, as long as air-conditioning is in the refrigeration mode operation, water in attemperater 4 all can be heated always, and will there be the potential safety hazard of attemperater 4 hypertonia in this.
In addition, in this air-conditioning system with heat recovery function, because attemperater 4 is connected in system, cold-producing medium 1 must carry out heat exchange through attemperater 4 when flowing from outdoor heat exchanger 2 to compressor, cause the air-conditioning heating effect to descend, therefore this air-conditioning system with heat recovery function can only be used for single refrigeration air-conditioner, and the heat pump type air conditioning system that can't be used for refrigeration, heat.
The utility model content
The utility model is to solve above-mentioned air-conditioning system with heat recovery function can't accurately control the problem that there are the potential safety hazard of hypertonia in water temperature, attemperater.
For this reason, the utility model provides a kind of air-conditioning system with heat recovery function, mainly formed by compressor, outdoor heat exchanger, indoor heat exchanger, attemperater, attemperater is connected on pipeline between outdoor heat exchanger and compressor, it is characterized in that: also have a magnetic valve and aforementioned attemperater to be connected in parallel on pipeline between outdoor heat exchanger and compressor.
In air-conditioning system with heat recovery function of the present utility model, because magnetic valve and attemperater are connected in parallel on pipeline between outdoor heat exchanger and compressor, the conducting of magnetic valve or closure make attemperater open or be connected to system from system break.
When air-conditioning system is under refrigeration mode that in operation and attemperater, water temperature has reached design temperature, control solenoid valve conduction, attemperater is just opened from system break, the cold-producing medium of HTHP directly enters outdoor heat exchanger through magnetic valve is laggard, the attemperater of not flowing through, therefore in attemperater, water temperature no longer rises, thereby stopped the potential safety hazard of attemperater hypertonia.When air-conditioning system is under refrigeration mode that in operation and attemperater, water temperature does not reach design temperature, control solenoid closure, attemperater is connected in system, the cold-producing medium of HTHP enters outdoor heat exchanger through attemperater is laggard, to water heating in attemperater, realize the air-conditioning system heat recovery function.
Therefore, the air-conditioning system with heat recovery function of the present utility model can accurately be controlled water temperature, stop the potential safety hazard that there is hypertonia in attemperater.
In addition, in the air-conditioning system with heat recovery function of the present utility model, can make attemperater open from system break by controlling solenoid valve conduction, when air-conditioning system is under heating mode operation, attemperater does not participate in heat exchange, therefore this air-conditioning system with heat recovery function also can be used for the heat pump air conditioner that freezes, heat.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 2, the air-conditioning system with heat recovery function of this embodiment mainly is comprised of compressor 1, outdoor heat exchanger 2, indoor heat exchanger 3, attemperater 4, magnetic valve 5.Wherein, magnetic valve 5 is normally closed, just understands conducting when namely switching on; Magnetic valve 5 and attemperater 4 are connected in parallel on pipeline between outdoor heat exchanger 2 and compressor 1.
As shown in Figure 3, when air-conditioning system is under refrigeration mode that in operation and attemperater 4, water temperature has reached design temperature, magnetic valve 5 energisings are in conducting state, the cold-producing medium of HTHP directly enters outdoor heat exchanger 2 through magnetic valve 5 is laggard, the attemperater 4 of not flowing through, therefore in attemperater 4, water temperature no longer rises, thereby stopped the potential safety hazard of attemperater 4 hypertonia.
As shown in Figure 4, when air-conditioning system is under refrigeration mode that in operation and attemperater 4, water temperature does not reach design temperature, magnetic valve 5 is in closure state, the cold-producing medium of HTHP enters outdoor heat exchanger 2 through attemperater 4 is laggard, to water heating in attemperater 4, realize the air-conditioning system heat recovery function.
As shown in Figure 5, when moving under air-conditioning system is in heating mode, magnetic valve 5 energisings are in conducting state, and cold-producing medium is directly got back to compressor through magnetic valve 5 after outdoor heat exchanger 2, the attemperater 4 of not flowing through does not exert an influence to the heating effect of air-conditioning.Therefore, this air-conditioning system with heat recovery function can be used for the heat pump air conditioner that freezes, heat.
In sum, the air-conditioning system with heat recovery function of this embodiment, can be by the control of magnetic valve 5, attemperater 4 is opened or connected from system break, can accurately control water temperature, stop the potential safety hazard of attemperater 4 hypertonia, the heat pump air conditioner that can make again this air-conditioning system be used for refrigeration, heat.
Be more than one of embodiment of the present utility model, for those skilled in the art, do not spend performing creative labour, can do multiple variation on the basis of above-described embodiment, can realize the purpose of this utility model equally.But this variation obviously should be in the protection domain of claims of the present utility model.
