Abstract
The invention provides a cooling circulation system of a rotor compressor pump body which comprises a pump body, an exhausting pipe, a liquid inlet pipe and a condenser, wherein an airtight cavity is arranged on the pump body, the upper end of the airtight cavity is connected with the condenser through the exhausting pipe, and the lower end of the airtight cavity is connected with the condenser through the liquid inlet pipe. Compared with the prior art, the cooling circulation system can cool the pump body in a casing, transmits the heat generated in the air compressing process to the external environment of the compressor, accordingly reduces the temperature of exhausted air and air suction degree of superheat and improves efficiency of the compressor.
Description
Technical field
The present invention relates to compressor, relate in particular to a kind of rotor compressor pump housing cooling recirculation system.
Background technique
The gas of the HTHP of discharging for compressor in the housing of high back pressure rotor compressor; The pump housing in the housing is surrounded by the gas of HTHP; And pump housing material is generally cast iron; Its capacity of heat transmission is stronger, and the heat in the housing can pass to the gas in air-breathing and the compression process, thereby reduces the efficient of compressor.And low back pressure rotor compressor be the gas of low-temp low-pressure in the housing, the heat that compressor operating produces by GAS ABSORPTION in the housing after, can improve the degree of superheat of suction gas, thereby also can reduce the performance of system.
In order to reduce the performance loss that pump housing heat transfer causes, have many researchers to attempt adopting the big material of thermal resistance to process pump housing parts, but because pump housing parts are had relatively high expectations to thermal expansion, surface Machining etc., new material is difficult to satisfy simultaneously all requirements.
Air-conditioning system circuit pressure-enthalpy chart is as shown in Figure 1, and the circulating path of conventional system is A-B '-C-D-A, the input power of compressor be (h2 '-h1); In the pump body compression process, if can the heat that gas produces be taken away, then the circulating path of system is A-B-C-D-A, and the input power of compressor then is (h2-h1).By Fig. 1 visible (h2-h1)＜(h2 '-h1), promptly in the pump body compression process, if the heat that gas is produced is taken away, then compression horsepower can reduce, promptly the efficient of compressor can be increased dramatically.But how the heat of gas generation is taken away, also do not reported at present.
Summary of the invention
The object of the invention for a kind of delivery temperature and suction superheat of reducing is provided, improves the rotor compressor pump housing cooling recirculation system of compressor efficiency exactly.
In order to achieve the above object; The present invention has adopted following technological scheme: a kind of rotor compressor pump housing cooling recirculation system, and this system comprises the pump housing, it is characterized in that; Also comprise outlet pipe, liquid inlet pipe and condenser; The described pump housing is provided with closed cavity, and this closed cavity upper end connects condenser through outlet pipe, and the lower end connects condenser through liquid inlet pipe.
The described pump housing comprises upper cylinder cover, cylinder and following cylinder cap, and described closed cavity is arranged on upper cylinder cover, cylinder or the following cylinder cap.
The described pump housing also comprises intermediate plate, and described closed cavity also can be arranged on the intermediate plate.
The position of described condenser is higher than the height and position of closed cavity.
The refrigeration agent of described system and the refrigeration agent of air conditioner circulating system are identical or different.
Described rotor compressor is high back pressure rotor compressor or low back pressure rotor compressor.
Described rotor compressor is single-rotor compressor or two-spool compressor.
Compared with prior art, pump housing cooling recirculation system of the present invention cools off the pump housing in the housing, the heat transfer that produces in the pressurized gas process among the compressor external environment condition, thereby reduce delivery temperature and suction superheat, improve compressor efficiency.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Shown in Fig. 2-5, a kind of air conditioner circulating system comprises compressor 1, the first condenser 2, expansion valve 3 and vaporizer 4, and the relief opening of described compressor 1 connects first condenser 2, expansion valve 3 and vaporizer 4 successively, and vaporizer 4 connects the intakeport of compressors 1.
Above-mentioned compressor 1 is provided with pump housing cooling recirculation system in addition; This system is arranged on the pump housing of compressor; Comprise second condenser 5, outlet pipe 6 and liquid inlet pipe 7; The pump housing comprises upper cylinder cover, cylinder and following cylinder cap, and cylinder 8 is provided with closed cavity 9, and closed cavity 9 structures of offering on the cylinder are shown in Fig. 4-5.Connect two pipes up and down respectively at this closed cavity 9, and draw compressor housing and be connected with second condenser 5, promptly closed cavity 9 upper ends connect second condenser 5 through outlet pipe 6, and the lower end connects second condenser through liquid inlet pipe 7.
In pump housing cooling recirculation system, charge into and identical refrigeration agent or other refrigeration agents of air-conditioning circulation.During steady running, pump housing cooling recirculation system and air-conditioning system do not have the refrigerant exchange.Second condenser 5 is higher than the height and position of the closed cavity in the pump housing 9.Because action of gravity, liquid refrigerant concentrate in the enclosed space in the pump housing.Outlet pipe 6 positions that pump housing closed cavity 9 is connected are higher than liquid inlet pipe 7.
Pump housing cooling recirculation system working principle is as shown in Figure 3.Liquid refrigerant in the closed cavity 9 in the pump housing receives the heating of the pump housing and evaporates; Make the liquid level position in the interior closed cavity 9 of the pump housing descend; Because the effect of gravity, the liquid refrigerant in second condenser 5 can flow to the closed cavity 9 in the pump housing, make liquid level rise.Vaporized gas flows to second condenser 5, and in the atmosphere environment of second condenser 5 with heat transferred low temperature, gas is condensed into liquid in second condenser 5.So circulation, the gentle liquid proportional of pressure is relatively stable in the maintenance pump housing cooling recirculation system.
This closed cavity can be opened in intermediate plate, up and down on the miscellaneous part such as cylinder cap.Its shape is not limit, as long as can guarantee and the sealing of air conditioner circulating system refrigeration agent.
Above-mentioned pump housing cooling recirculation system is not only applicable to the high back pressure rotor compressor and is applicable to low back pressure rotor compressor yet.Be not only applicable to single-rotor compressor and be applicable to two-spool compressor yet.
