Description of the invention (2) The internal pressure of the cylinder is higher than the internal pressure of the closed container, so the pressure on the refrigerant sending side of the second rotary compression element is applied to push the second Back pressure chamber of the wing of the rotary compression element. However, when 'the refrigerant of such a multi-stage compression rotary compressor uses a high-low level refrigerant' such as carbon dioxide (CO 2) as the refrigerant, as shown in FIG. 6 'the refrigerant sending pressure reaches the second rotation of the high pressure (HP) When the element is compressed, it reaches 12MPaG. Therefore, when the historical force of the refrigerant delivery side of the second rotary compression element is applied to the back pressure chamber, the pressure of the fins against the rollers will be higher than the necessary high pressure, so that the sliding part of the fin tips and the outer periphery of the rollers will be burdened It is heavy, causing significant wear and damage to the wings and rollers. &Quot; The present invention is made to solve these technical problems, and its purpose is to improve the durability of the fins and rollers of the multi-stage compression rotary compressor with internal intermediate pressure, and prevent the fins and rollers from being damaged. . , Α, and 'In order to reduce the differential pressure (pressure difference) of the second stage, the thickness (height) of the cylinder of the first rotary compression element was changed so that the exhaust volume of the second rotary compression element was smaller than Exhaust capacity of the first rotary compression element However, according to such a setting method, since the thickness (height) of the first cylinder is increased, the cylinder material of the first rotary compression element and the & Eccentric parts, rollers and other components. In addition, due to the increase in the thickness (height) of the cylinder, the thickness of the rotary compression mechanism (increased in height) will increase the size of the entire multi-stage compression rotary compressor.

Description of the invention (3) The present invention is to solve such a problem of the prior art, and to reduce the manufacturing cost by providing as few components as possible, and to prevent the size of the compressor from increasing. In terms of the manufacturing method of the multi-stage compression rotary compressor with the most suitable exhaust volume ratio, it can be easily set. Furthermore, when a refrigerant with a high and low pressure difference, such as carbon dioxide (CO2), is used as the refrigerant, the pressure of the sent refrigerant is as shown in Fig. 7, and the second rotary compression element forming the high pressure Hp reaches 12 MPa. Above, on the one hand, the first rotary compression element forming the low-stage side is 8 MPaG (intermediate pressure MP) when the outside air temperature is 15 ° C (the suction pressure LP of the first rotary compression element is 4 MPaG). As a result, the differential pressure in the first stage (the difference between the suction pressure Lp of the first rotary compression element and the output pressure MP of the i-th rotary compression element) reaches a value as high as 4 MPaG. Moreover, the higher the outside air temperature, the i-th The output pressure Mp of the rotary compression element increases sharply, so the differential pressure in the first stage increases. When the differential pressure in the first paragraph is so large, the internal and external pressure difference between the sending valve used to open and close the sending port of the first rotary compression element is too large, and the durability and reliability of the sending valve may be reduced due to damage to the sending valve. The present invention has been made to solve such a problem of the prior art, and an object of the present invention is to provide a multi-stage compression type rotary compressor which can prevent a reduction in durability and reliability caused by an excessively large differential pressure in the first stage. If the differential pressure in the second stage of the conventional technique is increased, the pressure difference between the inside and outside of the sending valve of the second rotary compression element is too large, resulting in the problem that the pressure difference causes damage to the sending valve of the second rotary compression element. The present invention has also been made to solve such a technical problem, and provides a discharge valve for a second rotary compression element which can prevent the second stage differential pressure from occurring.

Description of the invention (5) For this reason, if a refrigerant flow path is provided to the evaporator without depressurizing the refrigerant sent by the first rotary compression element, it will pass through during defrost. The refrigerant flow path causes the refrigerant sent from the first rotary compression element to be also supplied to the evaporator, so that the problem of the pressure reversal between the sending and suction of the second rotary compression element can be avoided. But 'this situation will form the form where the sending side of the first rotary compression element communicates with the sending side of the second rotary compression element, so that the pressure on the suction side and the sending side of the second rotary compression element is the same.

Low-pressure room side. The sucked medium-pressure refrigerant gas is compressed by the action of the upper rollers 46 and the fins 50 into the second stage to become high-temperature-pressure refrigerant gas. The muffler chamber 62 in the upper supporting component 54 is then flowed into the gas cooler 154 through the refrigerant outlet pipe 96. At this time, the temperature of the refrigerant rises to about +10 (rc, so that the high-temperature and high-pressure refrigerant gas is heated to the water in the hot water storage tank by exotherm, and can be heated to about +90.00 hot water. On the one hand, the refrigerant It is cooled by the gas cooler 154, and flows out of the gas cooler 154.

Since the high-temperature refrigerant flows into the 'evaporator 1 5 7 and is heated, the frost is melted and removed. Since the solenoid valves 1 59 and 169 are open, the delivery side and the suction side of the second rotary compression element 34 are communicated through the refrigerant delivery pipe 9 6, the defrost pipe 1 8 and the refrigerant introduction pipe 92, In this situation, both sides will have the same pressure, but in the present invention, the solenoid valve 1 6 3 is closed during the defrosting operation, so the suction side (the refrigerant introduction pipe 9 2 side) of the second rotary compression element 34 is formed with A capillary state of 160 was interposed between the delivery sides (the refrigerant delivery pipe 96 side). Then, 'the first rotary compression element 32 is compressed and sent out of the closed container 12', and the refrigerant gas supplied to the second rotary compression element 34 through the refrigerant introduction pipe 92 is supplied to this capillary 16 The second rotary compression element 34. That is, because the pressure is reduced through the capillary i 60, the second rotary compression element 34 = a pressure difference is generated between the suction side and the delivery side, so that the fins can be prevented from falling. 'Unstable operation conditions during defrosting operation are avoided. , Which can improve reliability.
