Problems solved by technology

[0010] The purpose of the present invention is to address the deficiencies in the prior art, to provide a refrigeration constant temperature control method to achieve the purpose of temperature control, which can be applied to incubator products, and solve the problem that the prior art can only use fixed-frequency variable-frequency compressors for refrigeration. The frequency conversion compressor runs for too long. The cooling effect is poor and the technical problem is more power consumption.

Abstract

The invention relates to a refrigeration constant temperature control method and an incubator. The method comprises the following steps of step S1: detecting the temperature in the incubator and a set temperature value before the operation of an inverter compressor; step S2: setting frequency conversion conditions of the inverter compressor; step S3: after the inverter compressor is started, collecting operating parameters in the incubator; step S4: judging whether to adjust the frequency of the inverter compressor according to the operating parameters in the incubator and the frequency conversion conditions, and controlling the inverter compressor according to the result. The method and the incubator have the following advantages: the operating frequency of the inverter compressor is automatically adjusted according to a user set temperature and the operating parameters in the incubator, and a product is enabled to enter into an appropriate operation mode through measuring the loading condition in the incubator by means of collecting the current operating frequency and the time duration that the inverter compressor continuously operates in accordance with the current operating frequency, so as to avoid slow cooling caused by long time constant speed operation of the inverter compressor or a temperature overshoot phenomenon caused by excessive refrigeration, effectively prolong the service life of the product and the temperature control effect, and reduce energy consumption at the same time.

Description

technical field [0001] The invention relates to the technical field of frequency conversion refrigeration, in particular, a refrigeration constant temperature control method and an incubator Background technique [0002] In the experimental research of life sciences and the production of biotechnology products, it is often necessary to carry out necessary biochemical reactions, hybridization reactions, organism culture (including animal cells, plant cells and microorganisms) and the use of the above-mentioned cultured organisms for biotechnology Production of products. These biochemical reactions, hybridization reactions and organism cultivation need to provide appropriate temperature, necessary gas (oxygen and carbon dioxide gas are needed during organism cultivation) and sufficient mixing. Therefore, the corresponding incubator has been designed in the prior art. [0003] The current incubator products, especially those with constant temperature and humidity, use fixed-f...
