Problems solved by technology
This shutdown method of refrigeration equipment needs to rely on the pressure data collected by the pressure sensor to control the shutdown of the compressor. Due to the high cost of the pressure sensor, and it is not suitable for products such as refrigerators, the existing refrigeration equipment urgently needs a new one. Shutdown control method relying on pressure sensor

The invention relates to refrigerator equipment, a refrigerating system and a control method thereof and belongs to the field of refrigerating equipment. The refrigerating system comprises a refrigerant circulating hoop formed by connecting a condenser, an evaporator, a compressor and a throttling device and further comprises a heat regenerator. The control method comprises the following steps ofcontrolling to stop the throttling device when the refrigerating system needs to be stopped; acquiring refrigerant degree of superheat of one or more low pressure detection positions of the refrigerating system; corresponding to a condition that the refrigerant degree of superheat of one or more low pressure detection positions of the refrigerating system meets a preset superheat degree conditionand controlling to stop the compressor. The control method of the refrigerating system can reduce a refrigerant in the evaporator after stop on the one hand so as to reduce migration of the refrigerant in the evaporator to the compressor after stop to improve the reliable of system work and can enable the system to reach a stable and efficient state as soon as possible when being started again onthe other hand, thereby avoiding the cold quantity loss as the temperature of an air suction segment of the compressor is relatively low when a common system is just started.
Description
technical field [0001] The present application relates to the field of refrigeration equipment, for example, to a refrigerator equipment, a refrigeration system and a control method thereof. Background technique [0002] The electronic expansion valve is a throttling element that can adjust the refrigerant flow of the refrigeration device according to the preset program. It is often used for the throttling control of the refrigerant flow of refrigeration equipment such as refrigerators and air conditioners; In severe or wide range of operating conditions, traditional throttling elements (such as capillary tubes, thermal expansion valves, etc.) can no longer meet the requirements of comfort and energy saving. more and more widely used. [0003] The electronic expansion valve has the advantages of fast response and action speed. Generally, it only takes a few seconds to go from fully closed to fully open state. The opening and closing characteristics and speed can be set arti...
