Description
Technical field
The present invention relates to a kind of Teat pump boiler that hot water is provided, relate in particular to a kind of Phase Change Heat Accumulation Preheating Type Heat Pump Water Heater.
Background technology
The water heater of Xiao Shouing is mainly three kinds of solar water heater, gas heater and electric heaters in the market, has also mentioned heat pump water heater in the domestic patented technology data, comprises electronic heat pump water heaer and conventional compression type heat pump water heater.
All there are some problems and shortcomings in above-mentioned these water heater equipment.Solar water heater provides the ability of hot water to be subjected to the regional climate condition influence very big; Electric heater and gas heater use through for many years family and show and all have the hidden danger that jeopardizes personal safety always, there is the danger of getting an electric shock in electric heater, the danger that gas heater exists gas poisoning, suffocates is because of the report that uses this type of water heaters to die an unnatural death has finding repeatly; And electric heater and gas heater use natural gas, coal gas or electric energy to heat the domestic hot-water, and energy consumption is big, the operating cost height, and the coefficient of heat supply value is lower than 1.The heat pump water heater that existing patented technology specification proposes, theoretically, can reach safe and energy-conservation purpose, but also do not used so far by large-scale promotion, this be because: electronic chip that electronic heat pump water heaer uses costs an arm and a leg, and use direct current supply also needs special AC-DC conversion equipment; Conventional compression type heat pump water heater needs tank, and volume size is big, and input power is big, the manufacturing cost height.
Summary of the invention
The purpose of this invention is to provide a kind of Phase Change Heat Accumulation Preheating Type Heat Pump Water Heater.
It has evaporimeter, compressor, heating heat exchanger, heat storage and exchange device, restricting element, evaporimeter successively, water inlet pipe joins with heat taking and exchanging device, heating heat exchanger outer tube, outlet pipe successively, the other blower fan that is provided with of evaporimeter, in cool-bag, be provided with heat storage and exchange device, heat taking and exchanging device, phase-change heat-storage material, pipeline interlaced arrangement between heat storage and exchange device and the heat taking and exchanging device, heating heat exchanger is provided with the insulation layer outward, and the heat pump device is controlled by control and regulation equipment.
Phase Change Heat Accumulation Preheating Type Heat Pump Water Heater provided by the present invention is because used heat-storing device to come preheating cold water, thermic load when having reduced heat-pump hot water supply greatly, can use the required equipment of heat pump such as low power compressor, undersized evaporimeter and condenser like this, thereby the volume size of heat pump assembly is greatly reduced, and cost declines to a great extent; The present invention has higher coefficient of heat supply value, and energy-saving effect is remarkable; Compare with the sensible heat heat accumulation, the phase-change thermal storage system is because of the storage density height, and the volume of heat vessel greatly reduces, and the exothermic temperature equilibrium, and exothermic process is similar to isothermal, and the system that makes has highly stable heat supply water-based energy; The heat accumulation temperature of used phase-change material is low, and is little with the heat transfer temperature difference in the external world, thereby can reach good heat insulation effect; It is outdoor that whole water heater is installed in, as long as connect power supply and Inlet and outlet water, just can use, and compact conformation, is rationally installed and operated all very convenient.
Water heater provided by the present invention also has automatic defrosting system, can guarantee that water heater normally uses under lower environment temperature.
Water heater provided by the present invention can also use low price paddy electricity to carry out heat accumulation, and the operating cost of whole system is reduced, and economy is better.
Phase-change heat-storage material in the water heater provided by the present invention can use paraffin, Na

2Near the phase-change material of phase transition temperature such as O, capric acid 35～50 ℃, the latent heat of fusion of these materials and energy density are all bigger, and moderate.
Description of drawings
Accompanying drawing is Phase Change Heat Accumulation Preheating Type Heat Pump Water Heater's structural representation.
The specific embodiment
The Phase Change Heat Accumulation Preheating Type Heat Pump Water Heater mainly comprises the heat pump that blower fan 1, evaporimeter 2, compressor 3, restricting element 4, bypass defrost magnetic valve 5, control and regulation equipment 6, heating heat exchanger 7, insulation layer 8, phase-change heat-storage material 9, heat taking and exchanging device 10, heat storage and exchange device 11, cool-bag 12, cold water inlet pipe 13, hot water out pipe 14 etc. are formed.Cool-bag 12 is divided into two parts, and a part is a heat storage type heat exchanger, is made up of heat storage and exchange device 11, heat taking and exchanging device 10 and phase-change heat-storage material 9; Another part is a heating heat exchanger 7.
Under the situation of not using hot water, when the temperature of phase-change heat-storage material is lower than phase transition temperature, control and regulation equipment 6 can start heat pump work automatically, a flow through earlier passage of heating heat exchanger 7 of the gaseous refrigerant of the HTHP that compressor 3 produces, owing to do not feed cold water in another passage, the cold-producing medium condensation that can not be cooled, can only flow into cooling condensation heat release in the heat storage and exchange device 11, liberated heat is stored in the phase-change heat-storage material 9 with the form of latent heat and small part sensible heat, and the fusing point of phase-change material is about 35～50 ℃.The cold-producing medium that is condensed in heat storage and exchange device 11 enters evaporimeter 2 after restricting element 4 decompression, enter compressor 3 after the outdoor heat absorption evaporation to be compressed the back periodic duty.When the temperature of phase-change heat-storage material was higher than phase transition temperature, control and regulation equipment 6 can automatic cut-off system work.
Under the situation of using hot water, control and regulation equipment 6 also can start heat pump work automatically, cold water enters heat taking and exchanging device 10 from water inlet pipe 13, be preheated in another passage that enters heating heat exchanger 7 after 28～30 ℃ by phase-change heat-storage material 9, the high-temperature high-pressure refrigerant steam that produces with compressor 3 carries out heat exchange, after cooled dose of steam liberated heat is heated to 45～55 ℃, discharge, hot water is provided through hot water out pipe 14.Middle temperature (about 28～30 ℃) water cooling after the refrigerant vapour that comes out from compressor 3 is preheated heating heat exchanger is the heat storage and exchange device 11 of flowing through successively again behind the liquid, gets back to compressor 3 behind restricting element 4, the evaporimeter 2 and finishes heat pump cycle.
When outdoor evaporimeter 2 temperature were low, control and regulation equipment 6 can be opened bypass defrosting magnetic valve 5 automatically, and the high-temperature gas that compressor 3 is come out directly enters evaporimeter 2, evaporimeter 2 is defrosted, to guarantee its operate as normal.But the processing that do not defrost during hot-water supply, processings that only defrost at the intermittence that hot water stops confession is with the regular supply of assurance hot water.
The condenser that heating heat exchanger 7, heat storage and exchange device 11 constitute in the heat pump work system.Restricting element 4 is capillary, electric expansion valve or heating power expansion valve.Heating heat exchanger 7 is a double pipe heat exchanger, tubular heat exchanger, or plate-fin heat exchanger.Heat taking and exchanging device 10 and heat storage and exchange device 11 are the nest plate type heat exchanger, finned heat exchanger.
