Description
Technical field
The utility model relates to a kind of heat pump assembly, particularly a kind of device that utilizes heat-pump hot water supply.
Background technology
In the prior art, a kind of air source heat pump hot-water supply is arranged, mainly by compressor, condenser, system's magnetic valve, throttling arrangement, compositions such as evaporimeter, described compressor, condenser, throttling arrangement, evaporimeter links to each other successively, the outlet of evaporimeter links to each other with compressor inlet, be that compressor outlet is communicated with condenser inlet, the import of condensator outlet connected system magnetic valve, system's electromagnetic valve outlet is communicated with the import of throttling arrangement, the outlet of throttling arrangement is communicated with evaporator, the outlet of evaporimeter is communicated with compressor inlet, certainly, in the system gas and oil separating plant can also be arranged, filter, reservoir etc., described condenser comprises a heat absorption water cavity, evaporimeter one side is provided with blower fan, and throttling arrangement can be a capillary, also can be expansion valve; Working medium in the device can adopt R12, R22 or corresponding fluoro cold-producing medium etc., during device work, compressor sucks low-temp low-pressure working medium from evaporimeter, the gas working medium of HTHP after compression enters in the condenser, working medium is with absorb heat water in the water cavity of heat transferred in condenser, water temperature is raise, use for the people, working medium after condenser condenses becomes liquid, through gasifying in evaporimeter behind the throttling arrangement, absorbs heat from evaporimeter in the gasification again, the blower fan of evaporimeter is constantly blown over evaporimeter with air, heat energy in air is absorbed by evaporimeter, and in the compressed machine access to plant, and then transmit feedwater.Its weak point is: because the evaporating temperature in the evaporimeter is lower, in evaporator surface meeting frosting, after working long hours, frost is more and more, makes evaporimeter be difficult to the heat absorption from the external world, and the efficient of device reduces, and needs to defrost; At present, often adopt the method for two kinds of defrostings, the one, artificial defrosting needs to shut down for a long time, and influence is used; The 2nd, the heating power defrosting promptly allows the exhaust of compressor directly enter evaporimeter and makes its reverse circulation, and this moment, condenser served as evaporimeter, and during defrosting, condenser must absorb heat from environment, and this can cause supply water temperature to descend, and reduces quality of water supply; In addition, when outside air temperature was low, system low-voltage was corresponding to environment temperature; high pressure is corresponding to the temperature of water in the heat absorption water cavity, and the pressure reduction before and after the compressor is big, starts difficulty after the shutdown once more; for the refrigeration compressor of configuration unidirectional motor, this situation is more outstanding especially.
The utility model content
The purpose of this utility model provides a kind of air source heat pump hot-water supply, makes its also normal heat supply water of device when defrosting, and when guaranteeing the heat supply water quality, compressor can also unload startup.
The purpose of this utility model is achieved in that a kind of air source heat pump hot-water supply, comprise the compressor, condenser, system's magnetic valve, throttling arrangement and the evaporimeter that link to each other successively, the outlet of evaporimeter links to each other with compressor inlet, condenser is provided with the heat absorption water cavity, evaporimeter one side is provided with blower fan, be provided with a bypass branch road between the outlet of described compressor and the import of evaporimeter, described bypass branch road is provided with decompressor.
The utility model is when heating water, close the decompressor on the bypass branch road, the bypass branch road is disconnected, working medium forms a circulation between compressor, condenser, system's magnetic valve, throttling arrangement, evaporimeter, the condenser heat release constantly obtains operational hot water to water; When starting at low temperatures, can open the decompressor on the bypass branch road, make the inlet of the outlet of compressor through decompressor connection evaporimeter, like this, the compressor inlet outlet pressure differential is little, and low temperature lower compression machine starts convenient, and compressor is had unloading startup effect; When defrosting, the shutdown system magnetic valve, open the decompressor on the bypass branch road, the compressor air-discharging of HTHP can get around condenser and enter evaporimeter, and the frost that makes on the evaporimeter to be tied melts, reach the defrosting purpose, in defrost process, condenser is not worked, and compressor does not commutate, the water of heat absorption in the water cavity can be to the working medium heat release, thereby has improved the hot water delivery quality.The utility model can be applicable in the hot water supply system, locates as central heating, warm water swimming pool etc.
Described decompressor can be the pressure-reducing valve of Electromagnetic Control; Also can be order continuous bypass solenoid valve and capillary.These two kinds of designs all can effectively realize the purpose of this utility model, and its structure is all very simple, make, install, manage all very convenient.
