Example Embodiment

[0068] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0069] figure 1 It is the connection diagram of the basic air conditioning system according to the present invention.

[0070] like figure 1 As shown, the air-conditioning system used in general air-conditioning includes a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, a first throttling device 4, a gas-liquid separator 7 and an indoor heat exchanger 9. The connection structure is as follows: the four-way valve port of the four-way valve 2 is respectively connected with the exhaust port of the compressor 1, the outdoor heat exchanger 3, the inlet of the gas-liquid separator 7 and the indoor heat exchanger 9; the indoor heat exchanger 9 is also connected. A first throttling device 4 is provided on the pipeline connectin...

Abstract

The invention relates to a high heat unit, and a method, system and air condition for controlling the unit. According to the invention, a condensation side inlet and an evaporation side inlet of an intermediate heat exchanger are both connected with an indoor heat exchanger. A condensation outlet of the intermediate heat exchanger is connected with an outdoor heat exchanger. The evaporation side outlet of the intermediate exchanger is connected with a gas liquid separator. A pipeline connecting the evaporation side inlet of the intermediate heat exchanger with the indoor heat exchanger is provided with a third throttling device. A second throttling device is arranged on a pipeline connecting a condensation outlet of the intermediate exchanger and the outdoor heat exchanger. According to the invention, by adopting a method of heating low-pressure side cold medium by utilizing the intermediate heat exchanger and by controlling the opening degrees of the throttling devices based on a specific logic, the integral evaporation pressure and the evaporation temperature of the system are improved, the cold medium heat energy after condensation is utilized effectively, the integral heat exchange volume of the unit is improved and the low temperature heating capability is enhanced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a heat-intensive unit, a method for controlling the unit, a system and an air conditioner. Background technique [0002] With the improvement of people's living standards and the enhancement of energy-saving awareness, air conditioners have entered the majority of ordinary families and have been more and more widely used due to their energy-saving, flexible control, and easy installation and maintenance. However, when the air conditioner is in a low temperature state, due to factors such as relatively low evaporation temperature and easy frosting of the evaporator, the heat absorbed by the refrigerant from the air is greatly reduced, resulting in poor heating effect and affecting the user experience. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a strong heat type unit, a method for controlling the unit, a system and...
