Abstract
The utility model relates to a water heater capable of reliably defrosting, which comprises a systemic circulation loop that is composed of a compressor, a four-way valve, an outdoor heat exchanger, a throttling component, a one-way valve and an indoor heat exchanger, wherein the inner part of the indoor heat exchanger is provided with a defrosting pipeline which is connected with an air return pipeline of the systemic circulation loop by one end, and the other end is connected between the one-way valve and the indoor heat exchanger of the systemic circulation loop through the throttling component and an electromagnetic valve. Due to the adoption of a special defrosting pipeline for defrosting, the utility model avoids the problem that a water heating machine can not use the four-way valve to carry out reversal defrosting due to the peculiarity of the system. The utility model has the advantages of simple structure, low cost, simple process control of defrosting and stable system with reliability.
Description
Technical field
The utility model relates to hot water machine, particularly a kind of hot water machine that can reliably defrost, the innovative technology of genus hot water machine.
Background technology
The air-cooled heat pump hot water machine of present home and abroad, under the low temperature environment heating condition, the frosting of off-premises station regular meeting only needs the cross valve commutation when hot water machine need defrost in system, and condenser and evaporimeter " are exchanged ".But owing to be plate type heat exchanger at the used heat exchanger of air-cooled heat pump hot water machine mesohigh side, characteristic according to itself, if also so operation, may be in plate changes because the too low plate that causes of the working medium temperature that flows through changes the bursting by freezing damage, system can't be moved, can not carry out effective, defrosting reliably, influence the operate as normal of air-conditioner.Both guaranteed the needs that defrost, it is a technical problem that needs to be resolved hurrily that system is run well.
The utility model content
The purpose of this utility model is to overcome the existing shortcoming of hot water machine on Defrost technology, provides a kind of cost low, and defrost process control is simple, the hot water machine that can reliably defrost of system stability.
The purpose of this utility model can be realized by following technical proposals.
The utility model comprises the systemic circulation loop of being made up of compressor, cross valve, outdoor heat exchanger, throttle part, check valve and indoor heat exchanger, in indoor heat exchanger, be provided with defroster duct, defroster duct one terminates on the return line in systemic circulation loop, and the other end is connected between the check valve and indoor heat exchanger in systemic circulation loop by throttle part and magnetic valve.
Throttle part in the technique scheme systemic circulation loop is a capillary.
When the utility model used, when system's refrigerating operaton, the magnetic valve on the defroster duct was in closed condition, and no cold-producing medium flows through; During Defrost operation, magnetic valve is in open mode, after cold-producing medium flows through indoor heat exchanger, because the effect of check valve, cold-producing medium changes in the defroster duct, after the capillary-compensated step-down, enter defroster duct evaporation defrosting, return-air directly enters the muffler of compressor.Finish until defrosting, magnetic valve is in closed condition again.
The beneficial effects of the utility model are to adopt the defroster duct of a special use to defrost, and have avoided in hot water machine because the problem that can not use the cross valve reverse cycle defrost that the particularity of system causes.Simple in structure, cost is low, and defrost process control is simple, system stability, reliable.
Description of drawings
Fig. 1 is the schematic diagram in systemic circulation of the present utility model loop.Omitted among the figure and other irrelevant parts of the present utility model point.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in Figure 1, the utility model comprises the systemic circulation loop of being made up of compressor 5, cross valve 6, outdoor heat exchanger 7, throttle part 3, check valve 4 and indoor heat exchanger 8, throttle part 3 wherein adopts capillary, in indoor heat exchanger 8, be provided with defroster duct 1, defroster duct 1 can adopt a part of heat exchanger tube formation in the indoor heat exchanger 8, one of defroster duct 1 terminates on the return line in systemic circulation loop, and the other end is connected between the check valve 4 and indoor heat exchanger 8 in systemic circulation loop by capillary 2 and magnetic valve 10.
When the utility model used, when system's refrigerating operaton, the magnetic valve 10 on the defroster duct 1 was in closed condition, and no cold-producing medium flows through; During Defrost operation, magnetic valve 10 is in open mode, become high temperature and high pressure gas after compressed machine 5 compressions of cold-producing medium, behind cross valve 6, flow through indoor heat exchanger 8, because the effect of check valve 4, cold-producing medium can only pass through magnetic valve 10, through changing in the defroster duct 1 after the capillary 2 throttling step-downs, enter defroster duct 1 evaporation defrosting, return-air directly is back to compressor 5 through vapour liquid separator 9 again, whole process finishes until defrosting, and magnetic valve 10 is in closed condition again.
Claims (2)
