Abstract
The invention relates to a multiple-temperature-zone refrigeration system. The multiple-temperature-zone refrigeration system comprises refrigeration sub-systems at multiple levels. Except the refrigeration sub-system at the last level, a condenser outlet pipe of the refrigeration sub-system at any level is branched into a refrigeration pipe and a cooling pipe at a minimum, wherein each refrigeration pipe is connected with an evaporator in the refrigeration sub-system at the corresponding level and drives refrigerant to flow back to a compressor at the corresponding level; and each cooling pipe is used for cooling a condenser of the refrigeration sub-system at the downstream level and driving the refrigerant to flow back to the compressor at the corresponding level. The refrigeration pipes and the cooling pipes are each provided with a switching valve. Due to the fact that the refrigeration sub-systems at the multiple levels are arranged and in the refrigeration process, heat exchange is conducted between the condenser of the refrigeration sub-system at the downstream level and the refrigerant, at the low temperature, in the refrigeration sub-system at the upstream level, the refrigerant in the refrigeration sub-system at the downstream level can obtain the higher supercooling degree, and thus the refrigeration effect of the multiple-temperature-zone refrigeration system is effectively improved; and the requirement of multiple-temperature-zone refrigeration for the temperature is met. The invention further discloses a multiple-temperature-zone refrigeration control method used for controlling the multiple-temperature-zone refrigeration system.
