According to the scroll compressor, the rotating disc is driven by a motor to rotate, flow directions of a refrigerant are switched through the two grooves formed in the rotating disc, and an air conditioning system switches between refrigeration and heating; after the scroll compressor is applied to the existing heat pump system, a four-way valve can be omitted, and switching between refrigeration and heating can be realized.
Description
Technical field
The present invention relates to a kind of scroll compressor structure for heat pump, be used in heat pump and can cancel original cross valve, reduce pipeline, and then minimizing system leak, reduce heat energy loss, reduce production cost, belong to scroll compressor structure technical field.
Background technology
The energy and problem of environmental pollution are one of significant problems of facing of the world today, and the energy is the material base of modern society and life, and along with world population and economic increasing sharply, the consumption of the energy sharply increases, and causes environmental pollution constantly to aggravate.
Heat pump is energy-efficient with it, operating cost is low, energy regeneration, clean environment firendly, a tractor serves several purposes, the advantage such as stable is deeply by the favor of people.As shown in Figure 1, for present heat pump structural representation, after the refrigerant being positioned at heat exchanger 21 absorbs heat indoor, change it via cross valve 22 to flow to, the refrigerant after heat absorption is directed to compressor, is directed to heat exchanger 24 again after going out compressor by cross valve 22, to outdoor heat release, subsequently, then be back to heat exchanger 21 by capillary 23, form circulation.
Existing heat pump generally adopts cross valve 22 to change the flow direction of refrigerant, reaches the effect of cooling and warming.Because cross valve 22 can increase pipeline quantity, the fault rate of system can be improved when condition is slightly severe; Again due to cross valve 22 and the manufacture of pipeline many employings metal material itself, the heat energy loss of air is very large to external world, reduces the efficiency of air-conditioning system.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of compressor, and after adopting this compressor, original heat pump can cancel cross valve.
In order to solve the problems of the technologies described above, technical scheme of the present invention there is provided a kind of Scroll compressor for heat pump system, comprise casing, two ends in casing are respectively equipped with electric system and compressibility, worked by main shaft drives compressibility by electric system, it is characterized in that: the end face of casing is provided with high pressure chest dividing plate, cavity is formed between compressibility end face and high pressure chest dividing plate, compressibility and high pressure chest dividing plate have the centre bore and hole that communicate with this cavity, be provided with interface one, be covered on high pressure chest dividing plate after interface two and interface three, interface one and interface three communicate with heat exchanger and heat exchanger respectively, interface two communicates with the entrance of casing via pipe passage, rotating disk is sealed with between high pressure chest dividing plate and bonnet, rotating disk has separate cell body one and cell body two, rotating disk is driven to switch at refrigerating state and heating between state by motor,
When rotating disk is in refrigerating state, aperture is only communicated with interface three by cell body two, and meanwhile, interface one only communicates with interface two via cell body one;
When rotating disk be in heat state time, aperture is only communicated with interface one by cell body one, and meanwhile, interface three only communicates with interface two via cell body two.
Preferably, described cell body one is U-type groove one; Described cell body two is U-type groove two.
The present invention drives turntable rotation by motor, two cell bodies that rotating disk is arranged are utilized to switch the flow direction of refrigerant, realize the conversion between air-conditioning system cooling and warming, cross valve can be cast out after applying the present invention to existing heat pump to realize the conversion between cooling and warming.
