Title:
REFRIGERANT CIRCULATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/134520
Kind Code:
A1
Abstract:
A refrigerant circulating system, relating to the field of air conditioners, and being used for optimizing the effect of cooling an oil-less bearing (110). The refrigerant circulating system comprises a compressor (1), a first refrigerant flow path (2), and a second refrigerant flow path (3). The compressor (1) comprises a bearing cavity (111) and a bearing (110) provided in the bearing cavity (111); the first refrigerant flow path (2) is in communication with the bearing cavity (111) and is configured to cool the bearing (110); and the second refrigerant flow path (3) exchanges heat with the first refrigerant flow path (2) so as to cool a refrigerant in the first refrigerant flow path (2). According to the technical solution, supercooling of the refrigerant of the bearing (110) is implemented, so that the temperature of the refrigerant used for cooling the bearing (110) is low, the cooling effect of the bearing (110) is optimized, and the problem that heat is accumulated when the oil-free bearing (110) works is solved.
