Abstract

Disclosed is a refrigerant circulating system of a heat pump air conditioner. The refrigerant circulating system of the heat pump air conditioner comprises a compressor (3), a four-way valve (4), an outdoor heat exchanger (5), a throttling gear (6), an indoor heat exchanger (7), a liquid storage device (8), an electromagnetic valve (10), a first one-way valve (91) and a second one-way valve (92). After the first one-way valve (91), the liquid storage device (8) and the electromagnetic valve (10) are connected in series, the first one-way valve (91), the liquid storage device (8), the electromagnetic valve (10) and the second one-way valve (92) are connected on a pipeline between the throttling gear (6) and the outdoor heat exchanger (5) in parallel. When the air conditioner is in a heating mode, the electromagnetic valve (10) is switched on and the liquid storage device (8) is in a release state. A refrigerant which is filled in advance is released in the system to participate in work, the circulation volume of the refrigerant is increased, the heating effect of the air conditioner is improved, and the energy consumption of the air conditioner is lower.

Description

The coolant circulating system of heat pump air conditioner
Technical field
The utility model relates to a kind of coolant circulating system of heat pump air conditioner, belongs to the air-conditioning technique field.
Background technology
The coolant circulating system of existing heat pump air conditioner partly is made up of indoor part and outside, comprises compressor, cross valve, throttling arrangement, indoor heat exchanger, outdoor heat exchanger.This coolant circulating system belongs to the system of a sealing, and the coolant injection amount is to determine according to the performance of air-conditioning, can not change again in case just decide, and no matter air-conditioning is in and heats or running statuses such as refrigeration, high load capacity or underload.
Generally speaking, air-conditioning when heating mode moves than needing the more refrigerant of volume under the refrigeration mode.Otherwise air-conditioning can't reach heating effect preferably, and energy consumption is bigger.
The utility model content
The utility model is the air conditioner coolant circulatory system is made optimization, makes air-conditioning better effects if when heating mode moves.
For this reason, the utility model provides a kind of coolant circulating system of heat pump air conditioner, the coolant circulating system of heat pump air conditioner, comprise compressor, cross valve, outdoor heat exchanger, throttling arrangement, indoor heat exchanger, it is characterized in that: this coolant circulating system also comprises reservoir, magnetic valve, check valve one, check valve two, and wherein be in series back and check valve two of check valve one, reservoir, magnetic valve is connected in parallel on the pipeline between throttling arrangement and outdoor heat exchanger again.
Coolant circulating system of the present utility model should calculate the coolant quantity that need increase when heating mode moves than refrigeration mode, and be filled in the reservoir when air-conditioning dispatches from the factory during design.
When air-conditioning was in refrigeration mode, by the control magnetic valve, refrigerant was sealed up for safekeeping and is not worked in the reservoir.It is that the refrigerant flow direction is: the return-air mouth of the exhaust outlet → cross valve of compressor → outdoor heat exchanger → check valve two → throttling arrangement → indoor heat exchanger → cross valve → compressor.
When air-conditioning is in heating mode, by the control magnetic valve, the refrigerant flow direction is: the return-air mouth of the exhaust outlet → cross valve of compressor → indoor heat exchanger → throttling arrangement → magnetic valve, reservoir, check valve one → outdoor heat exchanger → cross valve → compressor.Therefore, reservoir is in release conditions, and wherein refrigerant is discharged into participation work in the system, makes refrigerant circulation increase.
Therefore, the coolant circulating system of heat pump air conditioner of the present utility model, can be by the automatic control of magnetic valve, realize that reservoir discharges, the storage refrigerant, thereby satisfy the operation under refrigeration, heating mode of same air-conditioning and make that to filling the different demands of coolant quantity refrigeration, heat-production functions better effects if, the energy consumption of air-conditioning are lower.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the coolant circulating system of the utility model heat pump air conditioner;
Schematic diagram when Fig. 2 is in refrigeration mode for the coolant circulating system of heat pump air conditioner embodiment illustrated in fig. 1, the arrow indication is that refrigerant flows among the figure;
Schematic diagram when Fig. 3 is in heating mode for the coolant circulating system of heat pump air conditioner embodiment illustrated in fig. 1, the arrow indication is that refrigerant flows among the figure.
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 1, the coolant circulating system of heat pump air conditioner, formed by indoor part 1 and outside part 2, comprise compressor 3, cross valve 4, outdoor heat exchanger 5, throttling arrangement 6, indoor heat exchanger 7, reservoir 8, magnetic valve 10, check valve 1, check valve 2 92.Wherein, be in series back and check valve 2 92 of check valve 1, reservoir 8, magnetic valve 10 is connected in parallel on the pipeline of 5 of throttling arrangement 6 and outdoor heat exchangers again.
When air-conditioning was in refrigeration mode, magnetic valve 10 cut out.At this moment, coolant circulating system as shown in Figure 2, the refrigerant flow direction is: the return-air mouth of exhaust outlet → cross valve 4 → outdoor heat exchanger 5 → check valve 2 92 → throttling arrangement 6 → indoor heat exchanger 7 → cross valve 4 → compressor 3 of compressor 3.Therefore, reservoir 8 is in store status, and wherein refrigerant is sealed up by magnetic valve 10 and check valve 1 and do not use.
When air-conditioning was in heating mode, magnetic valve 10 was opened.At this moment, coolant circulating system as shown in Figure 3, the refrigerant flow direction is: the return-air mouth of exhaust outlet → cross valve 4 → indoor heat exchanger 7 → throttling arrangement 6 → magnetic valve 10 of compressor 3, reservoir 8, check valve one 91 → outdoor heat exchanger 5 → cross valve 4 → compressor 3.Therefore, reservoir 8 is in release conditions, and wherein refrigerant is discharged into participation work in the system, makes refrigerant circulation increase.
In sum, the coolant circulating system of heat pump air conditioner of the present utility model, can be by the automatic control of magnetic valve 10, realize that reservoir 8 discharges, the storage refrigerant, thereby satisfy the operation under refrigeration, heating mode of same air-conditioning and make that to filling the different demands of coolant quantity refrigeration, heat-production functions better effects if, the energy consumption of air-conditioning are lower.
More than be one of embodiment of the present utility model, for those skilled in the art, do not spend performing creative labour, on the basis of above-described embodiment, can do multiple variation, 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.
