Abstract
The utility model discloses a deicing air source heat pump which comprises a compressor, a condenser, an evaporator and an electronic expansion valve, wherein the compressor is connected with the inlet of the condenser through a pipeline; the evaporator comprises a plurality of supercooling pipes; the supercooling pipes are divided into a plurality of groups and connected in series, thus forming a plurality of flow paths; one end of the bottommost flow path of the evaporator is connected with the outlet of the condenser, and the other end is connected with the inlet of the electronic expansion valve; the outlet of the electronic expansion valve is connected with the inlet of the evaporator; and the outlet of the evaporator is connected with the inlet of the compressor. As for the deicing air source heat pump, the flow path formed by the supercooling pipes at the bottommost end of the evaporator is connected with the condenser, therefore, refrigerant flowing out of the condenser can release part of heat to heat the bottom of the evaporator, thus being capable of effectively preventing the bottom of the evaporator from icing, and also being capable of improving the supercooling degree of refrigerant.
Description
Technical field
The utility model relates to a kind of air source heat pump, the air source heat pump that particularly a kind of device bottom that can avoid evaporating freezes.
Background technology
Air source heat pump is according to contrary Carnot cycle principle, adopt a spot of electric energy drive compression machine operation, make the liquid refrigerant of high pressure in evaporimeter, be evaporated to gaseous state (vaporization) through after the throttling, utilize axial flow blower from environment, to absorb a large amount of heat energy in air, the working medium of gaseous state is collapsed into the gas of high temperature, high pressure by compressor, entering condenser condenses then becomes liquid (liquefaction) that the heat that is absorbed is released to make to go in the water, so constantly water is heated in circulation, working medium after the heat exchange absorbs airborne heat again through expansion valve throttling cooling in evaporimeter.So go round and begin again,, realize the use of the air energy-new forms of energy of clean environment firendly, reusable edible with a large amount of airborne heats of a spot of electric energy acquisition.Because air source heat pump has the beneficial effect of energy-saving and environmental protection, therefore obtained application more and more widely.
There is a general problem in existing air source heat pump; under the promptly colder in the winter time environment; air source heat pump is in operation; it is unclean that the bottom of evaporimeter defrosting occurs through regular meeting; the phenomenon that the bottom freezes; seriously influence the use of air source heat pump, sometimes even can cause the damage of air source heat pump.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides the air source heat pump that a kind of device bottom that can avoid evaporating freezes.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of anti-freeze air source heat pump, comprise compressor, condenser, evaporimeter and electric expansion valve, described compressor is connected with described condenser inlet by pipeline, described evaporimeter is made up of several supercooling tubes, described several supercooling tube is divided into several groups of series connection and forms several flow processs, one end of described evaporimeter bottommost flow process is connected with the outlet of described condenser, the other end of described evaporimeter bottommost flow process is connected with the import of described electric expansion valve, the outlet of described electric expansion valve is connected with the import of described evaporimeter, and the outlet of described evaporimeter is connected with the import of described compressor.
Preferably, described evaporimeter is an evaporator fin.
Technique scheme has following beneficial effect: the flow process that this air source heat pump is made up of supercooling tube at the evaporimeter lowermost end is connected with condenser, the cold-producing medium that is flowed out by condenser still can be emitted the bottom heating of part heat to evaporimeter like this, so just can effectively avoid base of evaporator to occur freezing, and the degree of supercooling of cold-producing medium is improved.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, this anti-freeze air source heat pump comprises compressor 1, condenser 2, evaporimeter 4 and electric expansion valve 3, and evaporimeter 4 is an evaporator fin, and it is made up of several supercooling tubes 42, and several supercooling tubes 42 are divided into several groups of series connection and form several flow processs.Compressor 1 is connected with condenser 2 imports by pipeline, one end of evaporimeter bottommost flow process 41 is connected with the outlet of condenser 2, the other end of evaporimeter 4 bottommost flow processs 41 is connected with the import of electric expansion valve 3, the outlet of electric expansion valve 3 is connected with the import of evaporimeter 4, and the outlet of evaporimeter 4 is connected with the import of compressor 1.
This anti-freeze air source heat pump is when work, the cold-producing medium that flows out from condenser 2 need could can enter electric expansion valve 3 through the flow process 41 of evaporimeter 4 bottommosts to carry out throttling and lowers the temperature, cold-producing medium still can be emitted the bottom heating of part heat to evaporimeter when the flow process 41 of this bottommost of process like this, so just can effectively avoid base of evaporator to occur freezing, and the degree of supercooling of cold-producing medium is improved.
More than a kind of anti-freeze air source heat pump that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
