Accurate temperature control method for warm storage of independent refrigeration system compartment

Abstract

The invention discloses an accurate temperature control method for warm storage of an independent refrigeration system compartment, and relates to the technical field of refrigerators. The accurate temperature control method comprises the following steps: (1) setting a target temperature value T0; (2) setting a temperature rough adjustment lower limit temperature value T11 and a temperature roughadjustment upper limit temperature value T12; (3) setting a temperature fine adjustment lower limit temperature value T21 and a temperature fine adjustment upper limit temperature value T22; (4) performing detection and adjusting the temperature of the compartment to T0; (5) judging whether the compartment operates in a refrigeration or heating mode next time according to a real-time temperature variation amount; (6) performing refrigeration to lower the temperature to T21 and returning to step (5) when the internal temperature reaches T22, and performing heating to raise the temperature to T22 and returning to step (5) when the internal temperature reaches T21. By detecting the temperature variation, the accurate temperature control method for the warm storage of the independent refrigeration system compartment realizes quick judgment of the next operation mode, and avoids the situation that a system frequently switches between heating and refrigeration. Through the setting of a temperature fine adjustment range, the influence of the temperature inertia deviation of the compartment is reduced, and accurate 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
