Title:
COMPRESSOR AND HEAT EXCHANGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/024865
Kind Code:
A1
Abstract:
Disclosed is a compressor. The compressor comprises a crankshaft (10), and a first cylinder (20), a second cylinder (30) and a third cylinder (40) arranged sequentially in an axial direction of the crankshaft (10). The first cylinder (20) is a high-pressure cylinder, and the second cylinder (30) and the third cylinder (40) are low-pressure cylinders. The compressor also comprises a capacity variation switching mechanism (50) for controlling loading and unloading of the third cylinder (40). The compressor has a full operation mode and a partial operation mode. When the compressor is in the full operation mode, the capacity variation switching mechanism (50) loads the third cylinder (40) under the action of the discharge pressure of the compressor, and when the compressor is in the partial operation mode, the capacity variation switching mechanism (50) unloads the third cylinder (40) under the action of the inlet pressure of the compressor. Also disclosed is a heat exchange system comprising the compressor. With the capacity variation switching mechanism (50) provided in the compressor, at least one cylinders are allowed to be loaded or unloaded under the action of the capacity variation switching mechanism (50), thus enabling a capacity variation switching function of the compressor to meet operational requirements of different operating conditions and improve the heating capacity of the compressor under different operating conditions.
