Abstract
The utility model discloses a heat pump system of a heat pump water heater, which is the improvement of the current one, and comprises a compressor, a condenser, a restricting element and a evaporator connected through guide tubes according to the orders. A coil pipe is arranged outside the shell of the compressor, the two ends of which is connected on the loop of the evaporator. The advantages of the utility model is that the heat energy released into the environment is recycled and provided to the evaporator, therefore, the steaming pressure is increased, which improves the degree of superheat of the return air of the compressor in the environment of a low temperature. Through test, when the environment temperature is -5 DEG C, compared with the former, the heat efficiency is improved 30 percents, and the heating volume is improved 35 percents. Because the coil pipe is serially connected on the loop of the evaporator, the temperature at the evaporator is higher than the surrounded environment, the environment temperature of the evaporator operated without frost can be lower -5 DEG C. Even if the frost is produced in a low temperature environment, the frost-removing phase can be prolonged and the heating efficiency can be improved.
Description
Technical field
The utility model relates to a kind of heat pump of Teat pump boiler, is the improvement to the heat pump of existing Teat pump boiler.
Background technology
The heat pump of existing Teat pump boiler or title heating loop are as shown in Figure 2, this heat pump mainly by compressor 1 ', condenser 2 ' (being the metal condensation coil pipe), restricting element 3 ', evaporimeter 4 ' by conduit is by being formed by connecting in turn, its working mechanism is: cold-producing medium is from compressor 1 ' come out, form high temperature and high pressure gas, by conduit introduce the condenser 2 place the water heater storage tank ', by condenser 2 ' with the water heater storage tank in the water heat exchange after, become cryogenic high pressure liquid, introduce restricting element 3 ' decompression through conduit again, become low-pressure liquid, enter evaporimeter 4 ' flash to gaseous state then, then from evaporimeter 4 ' come out to get back to compressor to circulate once more.By above-mentioned circulation, by the condenser 2 ' water at low temperature in the storage tank is become high-temperature water.But, this heat pump in actual applications, to run into the problem of two aspects inevitably: the one, along with the reduction of environment temperature, evaporimeter 4 ' evaporation performance significantly reduce, compressor 1 ' suction and discharge pressure reduction increases, the density of the cold-producing medium of compressor 1 ' suction reduces, the circular flow of heat pump internal refrigeration storage agent reduces, the heat that causes heat pump to provide in storage tank reduces, when particularly environment temperature is lower than-5 ℃ in the winter time, its thermal efficiency is very undesirable, sometimes even the thermal efficiency occurs and be lower than 1, cause heating capacity and do not reach requirement, the not hot situation of hot water occurs, thereby influenced the popularization of Teat pump boiler on market to a great extent, influenced the competition between Teat pump boiler and other the traditional water heaters; The 2nd, when environment temperature is lower than-5 ℃, evaporimeter 4 ' the easy frosting of outer surface, and the existence of frost can influence the evaporation effect of evaporimeter 4 ' middle cooling fluid, the heating efficiency of heat pump is obviously descended, therefore, need regularly evaporimeter 4 ' carry out defrost, and defrost periods is short more, the heating efficiency of whole heat pump is just low more.
Summary of the invention
Task of the present utility model is the heat pump that a kind of Teat pump boiler will be provided, it is to utilize the heat dissipation capacity of compressor housing to improve the return-air degree of superheat of evaporating pressure and compressor, improve the heating capacity under the worst cold case, be beneficial to improve the heating capacity and the heating efficiency of heat pump, prolong the defrost periods of evaporimeter.
Task of the present utility model is finished like this, a kind of heat pump of Teat pump boiler, it by compressor 1, condenser 2, restricting element 3, evaporimeter 4 by conduit by connecting and composing in turn, be characterized in: be arranged with coil pipe 5 outside the housing of described compressor 1, the two ends of coil pipe 5 are connected on the loop of evaporimeter 4.
The outer surface of coil pipe 5 described in the utility model is enclosed with heat-insulation layer 6.
The material of coil pipe 5 described in the utility model is a metal.
Metal described in the utility model is a copper.
Restricting element 3 described in the utility model is any one in capillary, electric expansion valve, heating power expansion valve, the choke valve.
The utility model is because after adopting said structure, one of advantage, reclaimed compressor and be discharged into heat (case temperature of compressor can reach 80-90 ℃) in the environment originally, the heat that reclaims is offered evaporimeter 4, improved evaporating pressure, improved in the low temperature environment lower compression machine return-air degree of superheat, after tested, when environment temperature-5 ℃, its thermal efficiency improved 30% more originally, and heating capacity improves 35%; Two, because coil pipe 5 is connected on the loop of evaporimeter 4, make evaporimeter 4 places because of the projecting environment temperature of being heated, therefore the environment temperature of evaporator non-frost operation can be lower than-5 ℃, even if under lower environment temperature, finish frost, defrosting cycle also can prolong, from and improved heating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the heat pump of the Teat pump boiler in the prior art.
The specific embodiment
Please refer to Fig. 1, the heat pump of the utility model Teat pump boiler mainly by compressor 1, condenser 2, restricting element 3, evaporimeter 4 by conduit by being formed by connecting in turn, coiling has coil pipe 5 outside the housing of described compressor 1, coil pipe 5 is a bronze pan tube, and its a pair of exit is serially connected in respectively on the loop of evaporimeter 4.Outer surface at coil pipe 5 is enclosed with heat-insulation layer 6, and heat-insulation layer 6 mats play heat-insulation and heat-preservation.Restricting element 3 can be selected any one in capillary, electric expansion valve, heating power expansion valve, the choke valve etc. for use.
Request in person continuation down and describe the course of work of the utility model heat pump referring to Fig. 1: the gas of the HTHP that comes out from compressor 1 is introduced condenser 2 by copper pipe, after the abundant heat exchange of the water in the water heater storage tank 7, become cryogenic high pressure liquid, the choke valve of introducing as restricting element 3 through copper pipe reduces pressure again, become low-pressure liquid, enter evaporimeter 4 then and flash to gaseous state, then coming out to get back to compressor 1 from evaporimeter 4 circulates once more, by above-mentioned circulation, water heating by burying in the 2 pairs of water heater storage tanks 7 of condenser that are dipped in the water heater storage tank 7 makes water at low temperature become high-temperature water; Meanwhile, the heat transferred coil pipe 5 that gives out from compressor 1 surface of shell, i.e. heat exchange by housing and coil pipe, being flowed through by the air heat sources in the coil pipe 5 is recycled in the compressor 1 behind the evaporimeter 4 again, thereby improves the heating capacity and the heating efficiency of heat pump by the return-air degree of superheat that improves evaporating pressure and compressor.In addition, in the winter of cold, heat pump of the present utility model also can greatly prolong the defrost periods of evaporimeter 4, thereby has further improved heating efficiency.
