Description
Technical field
The utility model relates to a kind of heat pump water heater technical field, and specifically, particularly one is from heat production mutual defrosting air source heat pump water heater.
Background technology
Air source hot pump water heater is a kind of energy-saving equipment of scientific utilization electric energy grade.The air heat source of air source heat pump grows on trees, the most convenient, extensively used, particularly directly-heated type air source hot pump water heater, is the temperature continuous print feeding storage tank cold water supplemented directly being heated to setting, the water iterative cycles of storage tank need not be heated, within several minutes, just hot water can be obtained so start shooting, and the temperature stabilization of storage tank can be kept, give full play to the volumetric efficiency of storage tank, be generally subject to user and welcome.But temperature is close to zero degree wet weather in the winter time, easy frosting when air source heat pump runs, frost layer hinders the heat transfer of evaporimeter, and heat pump efficiency is reduced rapidly.Therefore, air source heat pump must defrosting very well.The Defrost method of current employing mainly contains reverse circulation and bypass hot gas defrosting, or has auxiliary electrical heater to defrost.Experimentally research and actual use, the shortcomings such as it is short that reverse circulation has defrosting time, and defrost advantage thoroughly, but during defrosting, system pressure variation is violent, occasionally has the heat exchanger tube break accident of wind regime evaporimeter, System recover length normal time; Bypass hot gas defrosting can overcome whole shortcomings of reverse circulation, but defrosting time is long, and the work done during compression depending merely on compressor when the thick evaporimeter of frost layer maintains 0 DEG C is for a long time difficult to ensure that defrosting thoroughly.The defrosting of directly-heated type air source hot pump water heater is than circulating difficulty, and main cause is the origin of heat lacking defrosting.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, provides a kind of from heat production mutual defrosting air source heat pump water heater, and it has the advantages such as efficient, reliable, energy-saving and environmental protection.
The utility model solves the technical scheme that its technical problem adopts: a kind of from heat production mutual defrosting air source heat pump water heater, comprises compressor, oil eliminator, gas-liquid separator, cross valve, phase transition heat accumulation unit, the first magnetic valve, turbine flowmeter, thermometer, boiler, hot water outlet, the second magnetic valve, assisted heating device, cold water inlet, the 3rd magnetic valve, water circulating pump, indoor heat exchanger, throttling arrangement and outdoor heat exchanger, described compressor upper end is connected with oil eliminator lower end, compressor lower end is connected with gas-liquid separator left end, described oil eliminator upper end is connected with cross valve left end, described cross valve right-hand member is connected with gas-liquid separator upper end, cross valve lower end is connected with outdoor heat exchanger left end, cross valve upper end is connected with phase transition heat accumulation unit left end, described phase transition heat accumulation unit upper right side is by the first magnetic valve, turbine flowmeter is connected with boiler left upper end with thermometer, phase transition heat accumulation unit lower end is connected with boiler lower-left end with thermometer by water circulating pump, described boiler is provided with assisted heating device, described hot water outlet is connected with boiler upper right side by the second magnetic valve, described cold water inlet is connected with boiler lower end by the 3rd magnetic valve, described indoor heat exchanger right-hand member is connected with phase transition heat accumulation unit bottom righthand side, described outdoor heat exchanger right-hand member is connected with indoor heat exchanger left end by throttling arrangement.
As preferably, described boiler is provided with heat-insulation layer.
As preferably, described thermometer adopts thermocouple thermometer.
As preferably, the pipeline that described water circulating pump is connected with boiler lower-left end is provided with temperature-sensing valve.
When summer, unit pressed refrigeration mode operation, most of condensing units that can will immediately discharge, be stored in the phase-change material of heat exchanger, unnecessary condenser heat is discharged in outdoor environment by air-cooled condenser; When needs use hot water, in boiler, need the water heated to enter in phase-change heat-exchanger by water circulating pump, with the phase-change material heat exchange of heat accumulation, obtain heat, improve temperature after form supply domestic hot-water.If the temperature requirement that hot water temperature needs when not reaching use, supply water temperature can be improved by the form of auxiliary electrical heater.When storing heat energy, air source heat pump system runs, and compressor operating produces the cold-producing medium of HTHP, and by a set of coil pipe release heat in phase change heat storage tank, phase-change material is constantly heated until melt, and stores condenser heat.When taking heat energy, open water-heater system, the another set of coil pipe that running water flows through in phase change heat storage tank absorbs heat, and hot water flows into boiler.Water receiving pipe bottom boiler, be connected to running water pipe at phase transformation tank entry place, the mouth of pipe has temperature-sensing valve, the valve opening when the water temperature in boiler is less than 40 DEG C, the hot water of not enough temperature mixes with running water and flows into that phase change heat storage tank is interior continues heat exchange, until temperature-sensing valve cuts out when in boiler, water temperature reaches 40 DEG C, hot water can supply domestic hot-water.
The utility model compared with prior art has the following advantages: compared with traditional water thermal storage hot-water heating system, in heat regenerator, dose phase-change material store heat, air-conditioning cooling and water heater hot water demand's nonsynchronous problem on time and consumption can be solved; The both energy-conserving and environment-protective of this system, again can in stable operation under high energy efficiency ratio; The cheap heat utilizing heat pump self to produce defrosts, and without the need to calling hot water to defrost from storage tank, improve defrost performance ratio, in turn simplify equipment, can reduce the thermal loss of pipeline during defrosting.
