Problems solved by technology

[0002] At present, the large-scale cold water heat pump devices on the market are all screw type and centrifugal type products. Whether it is a screw type or centrifugal type heat pump equipment, the screw compressor and centrifugal compressor used both use oil-lubricated bearings. Traditional heat pumps with oil systems The equipment has brought many hidden dangers to the reliability of the system, such as compressor stuck due to lack of oil, motor burnt, etc., and oil brought into the system will cause the performance of the unit to decline and the heat transfer coefficient of the heat exchanger to decrease

Abstract

The invention relates to a middle-deep layer geothermal magnetic suspension centrifugal heat pump device which comprises a magnetic suspension centrifugal compressor, a condenser, an evaporator and a geothermal heat exchanger. An exhaust port of the magnetic suspension centrifugal compressor is connected with the condenser, the condenser is sequentially connected with a filter, an expansion valve and the evaporator, and the evaporator is connected with an air suction port of the magnetic suspension centrifugal compressor; the condenser is further connected with the magnetic suspension centrifugal compressor through a cooling valve; an electric valve is further arranged between the air suction port and the exhaust port of the magnetic suspension centrifugal compressor; and the evaporator is connected with a geothermal pipe heat exchanger through a liquid inlet pipe and a liquid outlet pipe correspondingly. The magnetic suspension centrifugal compressor is used for replacing a traditional oil lubrication bearing device, so that the existence of a mixture of oil and a refrigerant in a system can be avoided, the attenuation of the refrigerating capacity of an oil system is avoided, and meanwhile, the performance of a heat pump system is greatly improved through the application of middle-deep layer geothermy.

Description

technical field [0001] The invention relates to a heat pump unit, in particular to a mid-deep geothermal magnetic levitation centrifugal heat pump device. Background technique [0002] At present, the large-scale cold water heat pump devices on the market are all screw type and centrifugal type products. Whether it is a screw type or centrifugal type heat pump equipment, the screw compressor and centrifugal compressor used both use oil-lubricated bearings. Traditional heat pumps with oil systems The equipment has brought many hidden dangers to the reliability of the system, such as the lack of oil causing the compressor to be stuck, the motor to burn out, etc., and the oil brought into the system will cause the performance of the unit to decline and the heat transfer coefficient of the heat exchanger to decrease. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, ...
