Title:
LOW-PRESSURE CHAMBER ROTARY COMPRESSOR AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/060816
Kind Code:
A1
Abstract:
A low-pressure chamber rotary compressor and an air conditioner, the low-pressure chamber rotary compressor comprising a housing (100), a motor assembly and a pump body assembly. The housing (100) is provided with a low-pressure intake component (120) and a high-pressure exhaust component (130). A low-pressure chamber (110) is provided within the housing (100), and the motor assembly is provided within the low-pressure chamber (110). The motor assembly comprises a stator (231) and a rotor (232). The pump body assembly comprises a crankshaft (210), a crankshaft casing (220), a cylinder (310), a piston (340), a sliding vane (330) and a bearing (320). The pump body assembly is provided within the low-pressure chamber (110). The piston (340), the sliding vane (330), the cylinder (310), the bearing (320) and the crankshaft casing (220) cooperate to form a compression chamber. A low-pressure refrigerant directly cools the rotor (232) and the stator (231), and the low-pressure refrigerant is heated and vaporized to increase the temperature of the vapor refrigerant before compression. The cylinder (310), the bearing (320) and the sliding vane (330) provided in the low-pressure chamber (110) are fully cooled to minimize thermal expansion and deformation. The piston (340) and the crankshaft (210) are provided in the cylinder (310), so that internal heat cannot be effectively dissipated to thereby obtain greater thermal expansion and deformation, which may effectively strengthen the sealing between the cylinder (310) and the piston (340), and improve the compression effect on the refrigerant.
