Abstract
The invention provides a hot water defrosting circulation system for a multi-connected air conditioner. The hot water defrosting circulation system comprises a compressor, the compressor is connected with a four-way valve, the four-way valve is connected with an outdoor heat exchanger, the outdoor heat exchanger is connected with an indoor heat exchanger, the indoor heat exchanger is connected with the four-way valve, the outdoor heat exchanger is further connected with a plate heat exchanger, and the plate heat exchanger is connected with a hot water tank and connected with the compressor through a solenoid valve. Hot water defrosting circulation with the plate heat exchanger as the main part is adopted, hot water stored in the hot water tank heats low-pressure refrigerants so that the refrigerants can absorb heat fast, the defrosting speed can be increased, and the comfort level of users is improved. Meanwhile, low pressure is effectively prevented from going beyond the operation range of the compressor, the operation of the compressor is stable, and the service life is effectively prolonged.
Description
Technical field
The present invention relates to a kind of air-conditioner defrosting circulating system, specifically refer to a kind of defrosting circulating system based on multi-connected air conditioner device.
Background technology
At present, Multifunction multi-connected air conditioner device has changed the operational mode of common air-conditioner, the multiple function of have refrigeration, heat, domestic hot-water processed supplying with floor heating or domestic hot-water uses.Existing multi-functional multi-connected air conditioner device is lower in outdoor temperature, outdoor unit heat exchanger meeting frosting while carrying out heating operation when air humidity is larger, prior art (as shown in Figure 1) is to commutate by air-conditioning cross valve, the hot gas that utilizes compressor to discharge enters outdoor heat exchanger and carries out defrost, the refrigerant liquid that becomes again low-temp low-pressure after throttling enters indoor set heat exchanger, and now indoor machine fan shuts down.There is following shortcoming in the method for this defrosting:
1,, because indoor machine fan stops, during defrosting, all by the defrosting of compressor self heat, defrosting time is longer.During defrosting, cannot give the indoor heat that provides, may cause indoor temperature to decline, user's comfortableness is bad.
While 2, defrosting, because indoor machine fan stops, the evaporation side of air-conditioning system cannot be absorbed heat from the external world, and low pressure liquid cannot evaporate completely, and low pressure can be lower on the one hand, particularly, under outdoor low temperature, may exceed the range of operation of compressor.Compressor has the danger of liquid hammer on the other hand.These are all influential to the life-span of compressor.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of multi-connected air conditioner device hot water defrosting circulatory system is provided, by increasing plate type heat exchanger, be that main hot water defrosting is circulated, utilization is stored in the hot water heating low pressure refrigerant in boiler, make refrigerant can absorb faster heat, thereby improve defrosting speed, users'comfort improves; Meanwhile, effectively prevent that low pressure from exceeding compressor operating scope.
For solving the problems of the technologies described above, the technical solution used in the present invention is a kind of multi-connected air conditioner device hot water defrosting circulatory system, comprise compressor, compressor connects cross valve, cross valve junction chamber external heat exchanger, and outdoor heat exchanger connects indoor heat exchanger, indoor heat exchanger connects cross valve, its outdoor heat exchanger is connecting plate type heat exchanger also, and plate type heat exchanger connects boiler, and plate type heat exchanger connects compressor by magnetic valve.
The above-mentioned multi-connected air conditioner device hot water defrosting circulatory system, its plate type heat exchanger connects compressor inlet by air inlet electromagnetic valve, and plate type heat exchanger connects exhaust outlet of compressor by exhaust solenoid valve.
The above-mentioned multi-connected air conditioner device hot water defrosting circulatory system, arranges water pump between its plate type heat exchanger and boiler.
The above-mentioned multi-connected air conditioner device hot water defrosting circulatory system, its outdoor heat exchanger exhaust ports arranges outdoor expansion valve.
The above-mentioned multi-connected air conditioner device hot water defrosting circulatory system, its plate type heat exchanger air inlet place arranges water module electronic expansion valve.
The above-mentioned multi-connected air conditioner device hot water defrosting circulatory system, its indoor heat exchanger air inlet arranges indoor expansion valve.
A kind of multi-connected air conditioner device hot water defrosting circulatory system of the present invention, during defrosting, exhaust solenoid valve is closed, and air inlet electromagnetic valve is opened, and outdoor expansion valve is opened, and indoor expansion valve cuts out; Running is as follows: the high temperature refrigerant gas of discharging from compressor enters outdoor heat exchanger by cross valve and carries out defrost, cold media gas is condensed into after liquid, the outdoor electric expansion valve of flowing through, then by the throttling of water module electronic expansion valve is laggard, enter plate type heat exchanger, utilize water pump that the hot water in boiler is circulated in plate type heat exchanger, after heat in refrigerant liquid absorption hot water, evaporate, then by compressor, sucked defrost cycle.Now, because the indoor expansion valve of indoor apparatus of air conditioner cuts out, refrigerant, without indoor apparatus of air conditioner, so can not absorb heat from indoor apparatus of air conditioner, has effectively avoided indoor temperature in defrost process to decline.
Tool of the present invention has the following advantages and useful technique effect:
1, by increasing plate type heat exchanger, be that main hot water defrosting is circulated, collect in time and store the heat producing in cyclic process, during defrosting, utilize and be stored in the hot water heating low pressure refrigerant in boiler, make refrigerant can absorb faster heat, thereby improve defrosting speed.
2, because the indoor expansion valve of indoor apparatus of air conditioner cuts out, refrigerant, without indoor apparatus of air conditioner, so can not absorb heat from indoor apparatus of air conditioner, has effectively avoided indoor temperature in defrost process to decline, and users'comfort significantly improves.
3, effectively prevent that refrigerant low pressure from exceeding compressor operating scope, safeguard the stability of complete machine operation, increase the service life.
4, make full use of the cyclic process of air-conditioning system inside, the heat that rationally uses each several part to store, energy-conserving and environment-protective, the operating efficiency of raising complete machine.
