Abstract

The invention discloses a heat exchange system and a control method thereof. The heat exchange system comprises a tank type heat exchanger and a compressor and is provided with a refrigeration mode and a heating mode. The control method of the heat exchange system comprises the steps that when the heat exchange system is in the refrigeration mode, whether the refrigeration consumed work of the heat exchange system in the refrigeration mode is greater than or equal to the first preset consumed work or not is judged; if the refrigeration consumed work is greater than or equal to the first preset consumed work, the heat exchange system is controlled to be switched to the heating mode so as to carry out oil return on the compressor; and when oil return is completed, the heat exchange system is controlled to be switched back to the refrigeration mode. According to the technical scheme of the heat exchange system and the control method thereof, the problem that lubricating oil of the compressor is accumulated in the tank type heat exchanger can be solved.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a heat exchange system and a control method for the heat exchange system. Background technique [0002] High-efficiency tank heat exchangers are being widely used in heat exchange systems due to their compact size and suitability for lean design. However, when the high-efficiency tank heat exchanger is in the cooling mode of the heat exchange system, the refrigerant is easy to accumulate at the bottom of the heat exchanger with the compressor lubricating oil. If the lubricating oil cannot return to the compressor for a long time, it will not only affect the heat exchange capacity of the high-efficiency tank heat exchanger, but also the compressor will burn out due to lack of lubricating oil. Contents of the invention [0003] The main purpose of the present invention is to provide a control method for a heat exchange system, aiming at solving the problem of compressor lubricating ...
