Control system of ice lining refrigerator

Abstract

The invention discloses a control system of an ice lining refrigerator. According to the control system, a pre-cooling mode control module is arranged in a refrigerator controller, a pre-cooling modecontrol program is stored in the module, and when the program is started, the controller controls the temperature of a cool storage system to be decreased into the lowest temperature state. An ice rowis arranged in a foaming layer of the refrigerator, a cool storage agent is added in the ice row, when an outage control program is started, the controller decreases the temperature of the cool storage agent in the ice row, and thus the cooling capacity in the ice row can be transmitted into the refrigerator after an outage. The control system can effectively ensure the maximum heat-insulation time of the outage, and the situation that after the outage occurs when a compressor is to be started, the heat-insulation effect of the ice lining refrigerator is poor is avoided; and meanwhile the problem that in order to keep the heat-insulation performance of the ice lining refrigerator under the outage, normal operation energy consumption is increased is avoided.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a control system for an ice-lined refrigerator. Background technique [0002] The ice-lined refrigerator realizes the stability of the temperature inside the refrigerator by precisely controlling the temperature of the ice lining layer, and avoids the temperature inside the refrigerator continuing to drop when a new load is added or the door is opened to directly control the temperature inside the refrigerator. Under this control method, the interval between compressor start-ups is very long. The power-off holding time of the system is greatly affected by the specific time of power-off. Ice-lined refrigerators have two features: first, the ability to precisely control the temperature. Every corner of the box can ensure a constant temperature of 2-8°C, providing a safe storage environment for active vaccines; second, the ability to store cold. In the e...

Problems solved by technology

Due to the uncontrollable shutdown time and power-off time of the products currently on the market, the actual power-off holding time may be much shorter than the maximum power-off holding time of the product, especially when the compressor is about to start up when the power is off, the actual power-off time The electric holding time will be close to the minimum power-off holding time of the product
