Abstract
The invention provides a kind of rotor compressor pump housing cooling recirculation system, this system comprises the pump housing, also comprises outlet pipe, liquid inlet pipe and condenser, and the described pump housing is provided with closed cavity, this closed cavity upper end connects condenser by outlet pipe, and lower end connects condenser by liquid inlet pipe.Compared with prior art, the present invention cools the pump housing in housing, and the heat produced in pressurized gas process is delivered among compressor external environment condition, thus reduces delivery temperature and suction superheat, improves compressor efficiency.
Description
Technical field
The present invention relates to compressor, particularly relate to a kind of rotor compressor pump housing cooling recirculation system.
Background technique
Be the gas of the High Temperature High Pressure of compressor discharge in the housing of high back pressure rotor compressor, the pump housing in housing is surrounded by the gas of High Temperature High Pressure, and pump housing material is generally cast iron, its capacity of heat transmission is stronger, heat in housing can pass to the gas in air-breathing and compression process, thus reduces the efficiency of compressor.And low back pressure rotor compressor, be the gas of low-temp low-pressure in housing, the heat that compressor operating produces, by after GAS ABSORPTION in housing, can improve the degree of superheat of suction gas, thus also can reduce the performance of system.
In order to reduce the performance loss that the transmission of pump housing heat causes, have many researchers to attempt adopting the large material of thermal resistance to process pump parts, but require higher to thermal expansion, surface Machining etc. due to pump parts, new material is difficult to meet all requirements simultaneously.
As shown in Figure 1, the circulating path of conventional system is A-B '-C-D-A to the pressure-enthalpy chart of Air Conditioning Cycle, and the input power of compressor is (h2 '-h1); In pump body compression process, if the heat that gas produces can be taken away, then the circulating path of system is A-B-C-D-A, and the input power of compressor is then (h2-h1).(h2-h1) < (h2 '-h1) as seen from Figure 1, namely in pump body compression process, if taken away by the heat that gas produces, then compression horsepower can reduce, and namely the efficiency of compressor can be increased dramatically.But how the heat that gas produces is taken away, also do not report at present.
Summary of the invention
Object of the present invention, exactly in order to provide one can reduce delivery temperature and suction superheat, improves the rotor compressor pump housing cooling recirculation system of compressor efficiency.
In order to achieve the above object, present invention employs following technological scheme: a kind of rotor compressor pump housing cooling recirculation system, 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 by outlet pipe, and lower end connects condenser by liquid inlet pipe.
The described pump housing comprises upper cylinder cover, cylinder and lower cylinder cap, and described closed cavity is arranged on upper cylinder cover, cylinder or lower cylinder cap.
The described pump housing also comprises intermediate plate, and described closed cavity also can be arranged on 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 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 the pump housing in housing, and the heat produced in pressurized gas process is delivered among compressor external environment condition, thus reduces delivery temperature and suction superheat, improves compressor efficiency.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 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 the first condenser 2, expansion valve 3 and vaporizer 4 successively, and vaporizer 4 connects the intakeport of compressor 1.
Above-mentioned compressor 1 is provided with pump housing cooling recirculation system in addition, this Operation system setting is on the pump housing of compressor, comprise the second condenser 5, outlet pipe 6 and liquid inlet pipe 7, the pump housing comprises upper cylinder cover, cylinder and lower cylinder cap, cylinder 8 is provided with closed cavity 9, and closed cavity 9 structure that cylinder is offered as illustrated in figures 4-5.Connect two pipes respectively at this closed cavity about 9, and draw compressor housing and be connected with the second condenser 5, namely closed cavity 9 upper end connects the second condenser 5 by outlet pipe 6, and lower end connects the second condenser by liquid inlet pipe 7.
The refrigeration agent identical with Air-conditioning Cycle or other refrigeration agents is filled with in pump housing cooling recirculation system.During steady running, pump housing cooling recirculation system and air-conditioning system exchange without refrigerant.Second condenser 5 is higher than the height and position of the closed cavity 9 in the pump housing.Due to Action of Gravity Field, liquid refrigerant concentrates in the enclosed space in the pump housing.Outlet pipe 6 position that pump housing closed cavity 9 connects is higher than liquid inlet pipe 7.
Pump housing cooling recirculation system working principle as shown in Figure 3.Liquid refrigerant in closed cavity 9 in the pump housing is subject to the heating of the pump housing and evaporates, liquid level position in the pump housing in closed cavity 9 is declined, due to the effect of gravity, the liquid refrigerant in the second condenser 5 can flow to the closed cavity 9 in the pump housing, makes liquid level increase.Gas flow second condenser 5 of evaporation, transfer heat in the atmosphere environment of low temperature by the second condenser 5, gas is condensed into liquid in the second condenser 5.Circulation like this, keeps the gentle liquid proportional of pressure in pump housing cooling recirculation system relatively stable.
This closed cavity can be opened in intermediate plate, on the miscellaneous parts such as upper and lower cylinder cap.Its shape is not limit, as long as can ensure and the sealing of air conditioner circulating system refrigeration agent.
Above-mentioned pump housing cooling recirculation system is not only applicable to 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.
