Scroll compressor wide area self-adaptation system

Abstract

The invention relates to a scroll compressor wide area self-adaptation system. The scroll compressor wide area self-adaptation system comprises a circulation main path composed of a compressor, a condenser, an expansion valve and an evaporator. A medium-pressure hole is formed in a middle pressure cavity of a static scroll plate of the compressor. A subcooler is arranged behind the condenser, outlets of the subcooler are divided into three paths, the path A and the expansion valve are connected to the circulation main path, the path B is connected to the medium-pressure hole of the compressorthrough a valve I, the path C is a branch path formed on the part, behind the subcooler and at the front end of the expansion valve, of the circulation main path and is connected with a valve II, andthe other end of the valve II is connected to the medium-pressure hole of the compressor. The medium-pressure hole of the compressor is further connected with a hot gas bypass, and the hot gas bypassis provided with a valve III. The three valves are all connected with a controller. The medium-pressure hole is formed in the middle pressure cavity of the static scroll plate, and gas-state refrigerant spraying, liquid-state refrigerant spraying and gas-liquid mixed state refrigerant spraying or medium pressure refrigerant discharging can be achieved through the medium-pressure hole. The system can efficiently work in the broad area.

Description

technical field [0001] The invention belongs to the application field of scroll compressors, and in particular relates to a wide-area adaptive system of scroll compressors. Background technique [0002] The compressor is the power core of the air conditioner system. It can compress the inhaled low-temperature and low-pressure refrigerant vapor to increase the temperature and pressure, circulate the refrigerant inside, and achieve the purpose of cooling or heating through the corresponding components. If the air conditioning system is compared to the human body system, the compressor is one of the most important components in this system, which is the core and heart. [0003] With the development and progress of society, the market has put forward higher and higher requirements for the energy efficiency, comfort and multi-purpose of the system, especially hoping to have a cooling / heating system that can not only be used in most areas. , and hope that this product is energy e...

AI Technical Summary

Problems solved by technology

[0004] At present, research in related fields has partially solved the above-mentioned problems required by the application, but there are still relatively large limitations, for example: the simple liquid spray technology can only reduce the exhaust temperature and increase the flow rate; the Copeland developed Air injection enthalpy (EVI) technology can improve low-temperature heating capacity and efficiency; hot gas bypass technology is widely used in air conditioning systems, which can connect the exhaust and low-pressure side, can adjust the capacity, and ensure the minimum suction pressure

[0005] Although the existing technologies can achieve a single function alone, or be used in combination to achieve a certain scope of application, the operating range of the unit is still limited, and the system is complicated and the cost is high
