Precise temperature control method for compartmental warm storage of independent refrigeration system

Abstract

The invention discloses a method for precise temperature control for warm storage in compartments of an independent refrigeration system, and relates to the technical field of refrigerators. The present invention includes step one: setting the target temperature value T0; step two: setting the lower limit of coarse temperature adjustment and the upper limit of coarse adjustment temperature values ​​T11, T12; step three: setting the lower limit of temperature fine adjustment and the upper limit of fine adjustment temperature values ​​T21, T22; step Four: pass the test and adjust the temperature of the compartment to T0; step five: judge the cooling or heating mode for the next operation according to the real-time temperature change; step six: when the internal temperature reaches T22, cool to T21 and return Step five; when the internal temperature reaches T21, then heat to T22, and return to step five. The invention detects the temperature change to quickly judge the next operation mode, and avoids the frequent switching of heating and cooling in the system; by setting the temperature fine adjustment range, the influence of the inertial deviation of the temperature of the compartment is reduced, and the precise temperature control is realized.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a method for precise temperature control for compartment warming of an independent refrigeration system. Background technique [0002] With the development of the times, the functions of refrigerators have been gradually improved, and refrigerators with variable greenhouses have gradually become popular. The variable room is more of a supplementary functional independent room, which will greatly increase the user's performance in terms of use. On the market, the adjustment range of refrigerators and greenhouses is mostly from -18°C to 5°C, which basically meets the storage needs of most foods. Similarly, refrigerators are also limited by their adjustment ranges and cannot achieve higher temperature storage. For example For warm storage drinks, the best storage temperature is around 22°C. [0003] The compartments of the independent refrigeration system have in...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for precise temperature control for compartment warming in an independent refrigeration system. By detecting the temperature change in step 5, the next operation mode of the compartment can be quickly and accurately judged, which solves the problem of the existing system. The problem of frequent switching between heating and cooling; by setting the temperature fine-tuning range, it solves the problem of temperature inertia deviation that is easy to occur when the existing room reaches the target temperature value for the first time, and realizes precise temperature control
