Refrigeration system, and control method thereof, and refrigeration equipment with refrigeration system

Abstract

The invention provides a refrigeration system, a control method thereof, and refrigeration equipment with the refrigeration system. The control method comprises the following steps that: whether a first outlet and a second outlet of a switching unit are closed, and respective temperature of a temperature changing chamber, a refrigeration chamber and a freezing chamber reaches the respective expected temperature is judged; when the first outlet is closed, the temperature of the temperature changing chamber does not reach the expected temperature and / or the temperature of the freezing chamber does not reach the expected temperature, a compressor is switched on and the second outlet is opened, and the temperature of the temperature changing chamber reaches expected temperature and the temperature of the freezing chamber reaches the expected temperature, the compressor is switched off; and when the second outlet is closed, the temperature of the refrigeration chamber does not reach the expected temperature, the compressor is switched on and the first outlet is opened, the temperature of the refrigeration chamber reaches the expected temperature but the temperature of the freezing chamber does not reach the expected temperature, the compressor is switched on and the second outlet is opened, the temperature of the refrigeration chamber reaches the expected temperature and the temperature of the freezing chamber reaches the expected temperature, and the compressor is switched off. In the refrigeration equipment, a storage chamber which is not used can be closed, so energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment control, in particular to a refrigeration system, a control method thereof, and refrigeration equipment with the refrigeration system. Background technique [0002] Three-door refrigeration equipment, such as a three-door refrigerator, generally includes a freezer, a cold room and a variable temperature room. In the prior art, a three-system control method can be used, such as figure 1 As shown, the individual control of the freezing chamber, the refrigerating chamber and the temperature-changing chamber is realized by controlling the outlet pipe A', the outlet pipe B' and the outlet pipe C' of the switching unit. The problem with this control method is that the control system is complex and the cost of the whole machine is relatively high. [0003] In addition, two systems can also be used to control the refrigerating room, freezing room and variable temperature room, such as ...

AI Technical Summary

Problems solved by technology

The problem with this control method is that the control system is complex and the cost of the whole machine is relatively high.

The problem with this control method is that if the evaporator in the variable temperature room is turned off, the cooling of the freezer can be realized through the refrigeration of the refrigerator-freezer, but the temperature control can only guarantee the temperature of one room, and there will be a difference between the refrigerator and the freezer. To control the temperature, if the refrigerating room is closed, the cooling of the freezing room can be realized through the variable room-freezing room refrigeration circuit. Similarly, there will be a room in the variable room and the freezing room that cannot reach the controlled temperature
