Description
Technical field
The utility model relates to technical field of heat pumps, particularly relates to a kind of heat pump internal conversion assembly and a kind of internal conversion heat pump.
Background technology
Heat pump comprises compressor, and the suction end of described compressor is connected with evaporimeter, and the exhaust end of described compressor is connected with condenser, is connected with throttling arrangement between described evaporimeter and described condenser.And heat pump may be used for cooling in summer and winter heating as air-conditioning use.This just needs source pump can realize the conversion of cooling condition and heating condition, to meet the needs of cooling in summer and winter heating.
At present, the cooling condition of heat pump and the conversion of heating condition have two kinds of modes: first external conversion mode, namely outside at heat pump, the water circulation of the energy source in machine room is exchanged between return pipe road for the water circulation of return pipe road and air-conditioning side, realizes the conversion of heat pump refrigerating operating mode and heating condition; It two is internal conversion modes, namely inner in source pump, is realized the conversion of heat pump refrigerating operating mode and heating condition by the flow direction changing cold-producing medium.
Wherein, internal conversion mode is generally taked cross valve to realize, and this internal conversion mode uses at present in some low profile thermal pump assemblys.And for earth source heat pump, because the general power of earth source heat pump is larger, unit is larger, not enough owing to being subject to installing space in source pump, later period maintenance maintenance is inconvenient, and the restriction waiting factors is inconvenient in operation switching, therefore, large-scale earth source heat pump generally adopts external conversion mode to carry out the conversion of heating condition and cooling condition.Fig. 1 in accompanying drawing is the cooling condition principle schematic of the earth source heat pump of existing external conversion pattern, Fig. 2 is the heating condition principle schematic of the earth source heat pump of existing external conversion pattern, see figures.1.and.2, the external conversion mode of earth source heat pump, beyond earth source heat pump, energy side, ground water circulation in machine room supplies between return pipe road for return pipe road and air-conditioning side water circulation, through four equal diameter pipes and eight isometrical valves, and the mode of the conversion heating and freeze of formation.Its transfer principle is: eight switching valves are divided into winter heating and cooling in summer two groups, by opening the logical combination of a group or closedown one group, changing four pipeline conductings and forming with cut-off the water-flow circuit heating or freeze, realizing the switching of winter and summer.In this external conversion mode, because the confession return pipe road of water circulation is complicated, caliber is larger, use conversion valve and conversion pipeline more, pipeline and valve be suspended on high in the air, therefore make that converting system cost is high, leftover problem is many, maintenance rate is high, inconvenient operation.For house ground source heat pump central air-conditioning system: in external conversion mode, the crossover connection of four diameter 400 millimeter, eight heavy valves, eachly weigh about 500 kilograms, thick heaviness.In the transfer process in winter or summer, operative employee needs to ascend a height manually to move huge valve handle.And if in water rigid impurity once fall in valve flashboard groove, valve will be not closed completely, the water of air-conditioning end because the pressure of building height pours in down a chimney can be able to be held to ground, overvoltage, water amount, soaked can be held with causing, underground pipe is even caused to be beyond the bearing capacity and to burst, cause permanent damage, cause total system to be scrapped further, consequence is quite serious.In addition, the converting system material outside in conversion regime and mounting cost account for 10% of system total cost, huge pipe-line system take that machine room area reaches the gross area more 20%.
And some earth source heat pump existing has also been carried out using cross valve to carry out the trial of internal conversion, but in the process of attempting, there are problems, such as, the four way solenoid valve that latus rectum is larger is on the market little, and poor sealing, very little magazine enters the spool of four way solenoid valve in time, and four way solenoid valve also can be caused to be not closed completely, and dependability is low.If use manual cross valve, it is firmly too large when manual cross valve is changed, make operator not easily realize manual operation, increase the weight of the work burden of operator, in addition, four way solenoid valve is used to carry out internal conversion, conversion pipeline is complicated, and the price of four way solenoid valve is higher, makes cost of investment higher, and the space taken in unit is comparatively large, installs inconvenient.
