Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following descriptions of the specific implementations are only exemplary, and it should be understood that the specific implementations described here are only used to explain the present invention, but not to limit the present invention and its application or usage.

[0041] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. In con...

Abstract

The invention relates to an air conditioning circulation system. A compressor, a condenser, a throttling device, an evaporator and a gas-liquid separator form a refrigerant circulating channel, a pipeline between a second opening of the condenser and the throttling device is provided with a heat exchange device, and the heat exchange device can conduct heat exchange with the gas-liquid separator.Through heat exchange, the temperature of a refrigerant in the pipeline between the second opening of the condenser and the throttling device is lowered, the condensate depression before throttling isincreased, the system refrigerating capacity is improved, and the air conditioner energy efficiency is improved. Meanwhile, through heat exchange, the temperature of a refrigerant in the gas-liquid separator is increased, the sucked air superheat degree of the compressor is increased, the long-time operation reliability of the compressor is ensured, and the efficiency of the compressor is improved advantageously. The invention further discloses an air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning circulation system and an air conditioner. Background technique [0002] An air conditioning cycle system usually includes a compressor, evaporator, throttling device, and condenser. The refrigerant discharged from the compressor is condensed by the condenser, throttled by the throttling device, then enters the evaporator, evaporates in the evaporator, and then enters the compressor, thus completing a cycle. [0003] Nowadays, the energy efficiency requirements of air conditioners in various countries are getting higher and higher. At present, there are two main methods for air conditioner manufacturers to improve energy efficiency. One is to increase the configuration of heat exchangers, but due to the limitations of heat exchangers, the energy efficiency of units is limited; the other is One is to add a subcooler to the outdoor unit to increase the...
