Embodiment Construction

[0025] It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0026] like figure 1 As shown, according to a specific embodiment of the present invention, an air conditioning system is provided, which includes an air conditioning system compressor 10 , an oil return line 20 and a heating line 40 . The oil return line 20 is communicated with the oil return end of the compressor 10 . The heating pipeline 40, at least part of the heating pipeline 40 is disposed adjacent to the oil return pipeline 20. When a refrigerant with a preset temperature is introduced into the heating pipeline 40, the heating pipeline 40 exchanges heat with the oil return pipeline 20 to improve the return flow. Return oil temperature of oil line 20.

Abstract

The invention provides an air conditioner system, an air conditioner system control method and an air conditioner. The air conditioner system comprises a compressor, an oil return pipeline communicating with the oil return end of the compressor, a heating pipeline which is at least partially adjacent to the oil return pipeline, wherein when a coolant with preset temperature is introduced into the heating pipeline, the heating pipeline exchanges heat with the oil return pipeline, to increase the oil return temperature of the oil return pipeline. By the arrangement of the heating pipeline which exchanges heat with the oil return pipeline, the coolant in the air conditioner system is introduced into the heating pipeline, and the coolant entering the heating pipeline can supply heat to the oil return pipeline, so that the oil return temperature in the oil return pipeline can be increased; and therefore, the viscosity of oil in the oil return pipeline is reduced, the oil return efficiency of the compressor is improved, and the service life of the compressor is effectively prolonged.

Description

technical field [0001] The present invention relates to the technical field of air conditioning equipment, and in particular, to an air conditioning system, a method for controlling the air conditioning system, and an air conditioner. Background technique [0002] In the prior art, the oil return control of the compressor generally adopts a scheme in which one compressor uses one oil return capillary to control the oil return. The oil return capillary used should not be too thick. Although too thick can improve the oil return rate, it will reduce the oil return performance. The oil return capillary should not be too thin. Although thinning can improve the performance of the unit, it will make the oil return capillary difficult to return oil and reduce the reliability. When a compressor adopts a capillary oil return method under ultra-low temperature conditions (-30°C and below), due to the increase of lubricating oil flocs in the oil and gas separator, the viscosity increas...
