Description
Technical field
The utility model patent relates to technical field of heat pumps, in particular, relates to a kind of low-temperature air-cooling heat pump system.
Background technology
Along with the development of heat pump techniques, the range of application of heat pump is more and more wider.
Very cold for winter in northern most area, under heating condition, because temperature is too low, air-cooled heat pump unit evaporimeter inner refrigerant can not evaporate completely, causes heat pump not start or the danger of liquid hammer.Also there is the serious problem of frosting in hot pump in low temp, frost layer plugs air channel, increases the thermal resistance between air and cold-producing medium simultaneously, greatly have impact on the heating effect of heat pump.
At present, solution heat pump does not start or liquid hammer problem is mostly arrange that electrical heating wire heats on an evaporator, improves temperature.Or adopt the high-efficient compressors such as frequency-changeable compressor, but add cost, simultaneously when temperature is too low, heat pump still can not start.
For the problem that frosting is serious, defrost when current heat pump acquires a certain degree according to frost layer, and must stop heat supply during defrosting, such system gross heat input declines, and heating effect difference also needs to consume a large amount of electric energy simultaneously.Defrosting water can congeal into ice after flowing on chassis, and along with the increase of defrosting number of times, condensation ice amount gets more and more, and finally causes evaporimeter bottom blocked, causes heat exchange to carry out.
Utility model content
The object of the utility model patent is the technological deficiency for existing in prior art, and provide a kind of heat utilizing system self to provide effectively to prevent air-cooled heat pump hot pump in low temp under microthermal climate from not starting or liquid hammer and the serious phenomenon of evaporimeter frosting, raising system gross heat input, improve security, meet the low-temperature air-cooling heat pump system of cold operation requirement simultaneously.
The technical scheme adopted for the object realizing the utility model patent is:
A kind of low-temperature air-cooling heat pump system, comprise compressor, condenser, choke valve, evaporimeter, magnetic valve and heating tube, described heating tube is installed on the bottom of described evaporimeter, the refrigerant outlet of described compressor is connected with the import of described condenser and magnetic valve respectively, the outlet of described magnetic valve is connected with the import of described heating tube, the outlet of described heating tube is connected with the import of described choke valve with after the outlet parallel connection of described condenser, the outlet of described choke valve is connected with the import of described evaporimeter, the outlet of described evaporimeter is connected with the import of described compressor.
The outlet conduit of described evaporimeter is provided with temperature sensor, and the signal output part of described temperature sensor is connected with controller, and the control end of described controller is connected with described magnetic valve.
Compared with prior art, the beneficial effect of the utility model patent is:
The heat pump of the utility model patent is arranged by shunting, base of evaporator heating tube is entered through magnetic valve at the outlet manifold part high-temperature gas of compressor, be used for bottom heating fumigators, by the fin of base of evaporator by heat conduction to the top of evaporimeter, improve the temperature of cold-producing medium in evaporimeter, keep rational operation of heat pump operating mode, realize cold-starting and liquid hammer do not occur.Meanwhile, make system while not stopping heat supply, avoid evaporating device frosting seriously, improve COP value, reach and improve gross heat input object.In addition, because the energy of heating tube is provided by system self, the object reducing energy consumption and environmental protection can be realized.

Figure 1 shows that the schematic diagram of the utility model patent low-temperature air-cooling heat pump system.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model patent is described in further detail.
The schematic diagram of the utility model patent low-temperature air-cooling heat pump system as shown in Figure 1, comprise compressor 1, condenser 3, choke valve 4, evaporimeter 5, magnetic valve 2 and heating tube 6, described heating tube 6 is installed on the bottom of described evaporimeter 5, by the fin bottom heating tube heating fumigators heat is delivered to the cold-producing medium in evaporimeter, the refrigerant outlet of described compressor 1 is connected with the import of described condenser 3 and magnetic valve 2 respectively, the outlet of described magnetic valve 2 is connected with the import of described heating tube 6, the outlet of described heating tube 6 is connected with the import of described choke valve 4 with after the outlet parallel connection of described condenser 3, the outlet of described choke valve 4 is connected with the import of described evaporimeter 5, the outlet of described evaporimeter 5 is connected with the import of described compressor 1.
The outlet conduit of described evaporimeter 5 is provided with temperature sensor, and the signal output part of described temperature sensor is connected with controller, and the control end of described controller is connected with described magnetic valve 2.By detecting the temperature of evaporator outlet, the open degree of Controlling solenoid valve, thus regulate the size adding heat.
The heat pump of the utility model patent is arranged by shunting, enter the water back of base of evaporator through magnetic valve at a part of high-temperature gas of the outlet manifold of compressor, be used for bottom heating fumigators, by the fin of base of evaporator by heat conduction in the cold-producing medium in evaporimeter, improve the temperature of cold-producing medium in evaporimeter.The open degree of magnetic valve is according to the size adjustment of evaporator outlet temperature, thus add amount of heat according to the adjustment of evaporimeter operating condition, keep rational operation of heat pump operating mode, realize cold-starting and liquid hammer do not occur, the device frosting that simultaneously avoids evaporating while not stopping heat supply is serious, improve COP value, reach and improve gross heat input object.In addition, because the energy of heating tube is provided by system self, the object reducing energy consumption and environmental protection can be realized.When temperature is higher in the winter time, closed electromagnetic valve carries out conventional heat pump operation.
The utility model patent hot pump in low temp system is applicable to low-temperature cold area.
The above is only the preferred embodiment of the utility model patent; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model patent principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of the utility model patent.
