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...

Examples

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] like figure 1 Shown is the structural schematic diagram of the compressor of the present invention. An intermediate pressure hole is opened in the middle pressure chamber of the fixed scroll of the compressor, and a connecting pipe is connected to the hole.

[0014] like figure 2 Shown is a schematic diagram of the system of the present invention. The system includes a main circulation circuit consisting of a compressor, a condenser, an expansion valve and an evaporator. The high-temperature and high-pressure gas generated by the compressor passes through the condenser to form medium-temperature and high-pressure gas, which is further cooled into low-temperature and low-pressure gas after passing through the expansion valve and evaporator, and finally returns to the compressor.

[0015] The system also includes three auxiliary loops ...
