Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0056] Such as image 3 As shown, the self-cascading heat pump cycle system includes compressor 1, oil-gas separator 2, four-way valve 3, air-cooled condenser 4, evaporator 5, separation liquid storage 6, evaporative condenser 7 and gas-liquid separator 8. The four-way valve 3 is provided with ports A, B, C and D. The outlet of the compressor 1 is connected to the inlet of the oil-gas separator 2, and the outlet of the oil-gas separator 2 is connected to the A port of the four-way valve 3. The D port of the four-way valve 3 is connected with the first port of the air-cooled condenser 4;

[0057] The inlet of the separation liquid storage 6 is connected with the second port of the air-cooled condenser 4 and the first port of the evaporator 5 respectively, and the second port of the separation liquid storage 6 and the second port of the air-cool...

Abstract

The invention belongs to the field of energy source power engineering and relates to an auto-cascade heat pump circulating system. An outlet of a compressor is connected with an inlet of an oil-gas separator. An opening A, an opening B, an opening C and an opening D of a four-way valve are connected with an outlet of the oil-gas separator, a second end opening of an evaporator, an inlet of a gas-liquid separator and a first end opening of an air cooled condenser correspondingly. An inlet of a separation liquid storage device is connected with a second end opening of the air cooled condenser and a first end opening of the evaporator. A liquid phase outlet of the separation liquid storage device is connected with a first inlet of an evaporation type condenser through a first throttling assembly. A gas phase outlet of the separation liquid storage device is connected with a second inlet of the evaporation type condenser. A first outlet of the evaporation type condenser is connected with an inlet of the compressor. A second outlet of the evaporation type condenser is connected with a second end opening of an air cooled condenser and a first end opening of the evaporator through a second throttling assembly. The auto-cascade heat pump circulating system overcomes the existing theory limitation and technological bias and is wide in application working condition range, high in energyefficiency ratio and small in attenuation under the low-temperature working condition.

Description

technical field [0001] The invention belongs to the technical field of energy and power engineering, and relates to a heat pump circulation system, in particular to a self-cascading heat pump circulation system. Background technique [0002] 1. The concept of heat pump [0003] Heat pump, according to the definition of the New International Dictionary of Refrigeration, a heat pump is a refrigeration system that uses the heat released by the condenser to provide heat. In fact, a heat pump is an application of a refrigerator. In terms of thermodynamics or working principle, both are heat transfer tools, but the refrigerator appeared earlier. In a broad sense, they are collectively called "heat pumps". more relevant. The main differences between the two are: First, the purpose of the two is different. The purpose of the refrigerator is to obtain low temperature; A refrigerator uses ambient temperature as a high-temperature heat source; a heat pump uses ambient temperature as...
