Scroll compressor and temperature adjusting equipment

Abstract

The invention discloses a scroll compressor and temperature adjusting equipment. The scroll compressor comprises a machine shell, a static scroll plate, a movable scroll plate, a crankshaft and a machine frame, the static scroll plate, the movable scroll plate, the crankshaft and the machine frame are arranged in the machine shell, the movable scroll plate and the static scroll plate are meshed toform a compression cavity, an air suction pipe penetrates through the machine shell to be inserted into the static scroll plate, and an air exhaust pipe is connected with the machine shell; the movable scroll plate can move in the axial direction between the machine frame and the static scroll plate within a certain range, the crankshaft penetrates through the machine frame, an eccentric part ofthe crankshaft is connected with a bearing seat of the movable scroll plate in a sleeved manner, and the eccentric part of the crankshaft and the bearing seat can relatively move in the axial direction; and an electromagnet is arranged on the crankshaft and / or the movable scroll plate and used for generating attraction force between the crankshaft and the movable scroll plate. The scroll compressor has the advantages that the starting load can be reduced, the compressor can be started without large starting torque, the problem that restarting is difficult is solved, and power consumption of the compressor is reduced.

Description

technical field [0001] The invention is used in the field of compressors, and in particular relates to a scroll compressor and temperature regulating equipment. Background technique [0002] When the scroll compressor stops, the casing is in a state of exhaust high pressure, and the pressure in the back pressure chamber cannot be released in time, so that the movable scroll and the static scroll are still in a compressed state, and then start again in a short time Compressor, due to the back pressure, the friction between the movable scroll and the fixed scroll is too large, and the gas in each compression chamber is also in a compressed state, resulting in excessive load, exceeding the maximum starting torque of the motor, resulting in difficulty in starting , or it can be started, but it consumes a lot of power. [0003] Moreover, when the scroll compressor restarts within a short period of time after stopping, it may be difficult to build up pressure at both ends of the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to at least solve one of the technical problems in the prior art, to provide a scroll compressor and a temperature adjustment device, which can reduce the starting load, and the compressor can be started without a large starting torque, solving the problem of Difficult starting problems again and reduced compressor power consumption
