The exhaust temperature control system of the air source heat pump can control the flow of the electric expansion valve, further controls the exhaust temperature of the compressor, prevents the compressor from overheating and ensures that the compressor can work at normal temperature.

Description

Air source heat pump delivery temperature control system
Technical field
The utility model relates to a kind of temperature control system, particularly a kind of control system of air source heat pump delivery temperature.
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 air energy---the use of 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.
But there is a problem in present air source heat pump, and the delivery temperature that enters compressor exactly is not easy controlled, the too high problem of compressor temperature occurs through regular meeting sometimes, influences the normal use of air source heat pump, brings inconvenience to the user.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of control system that the delivery temperature of air source heat pump is controlled.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
