Intelligent control circuit for direct cooling machine-controlled refrigerator

Abstract

The invention discloses an intelligent control circuit used for a direct cooling mechanical control refrigerator. The intelligent control circuit comprises a frequency conversion compressor, a filter, a frequency conversion control panel, a temperature sensor, a compensating heater, a magnetically controlled switch and a temperature controller, wherein two terminals of the frequency conversion control panel are respectively connected with two output ends of the filter; both the frequency conversion compressor and the temperature sensor are connected with the frequency conversion control panel; the compensating heater, the magnetically controlled switch and the temperature controller are sequentially connected in series and then are arranged between the two output ends of the filter in a connection mode; the frequency conversion control panel is used for controlling operating mode of the frequency conversion compressor; and the temperature controller is also connected with the frequency conversion control panel. The intelligent control circuit used for the direct cooling mechanical control refrigerator has the advantages that the fact that refrigerators in different volumes can be matched with one kind of compressors within a certain volume range under various kinds of working conditions is guaranteed, the optimum matching condition can be kept all the time, refrigerating capacity of large heat load of the mechanical control direct cooling refrigerator can be achieved, and the like.

Description

Technical field [0001] The invention relates to an intelligent control circuit for a direct cooling machine controlled refrigerator. Background technique [0002] In order to reduce the energy consumption of the refrigerator, in addition to optimizing the design of its components and improving the performance, improving the efficiency of the compressor, increasing the foam layer of the refrigerator or improving the performance of the foam material are the most important determinants. Although improving the efficiency of the compressor and enlarging the foaming layer of the traditional refrigerator contributes to energy saving, the freezing capacity cannot be increased due to the reduced operating rate of the refrigerator. There are two reasons why the large freezing load cannot pass the freezing capacity test: one is that the refrigerating room temperature exceeds zero, and the other is that the ballast or freezing load does not reach -18°C within the specified time.

Problems solved by technology

In this way, the adaptability of the cooling capacity of the whole system is relatively poor under different working conditions, and the working time of the compressor is relatively long under the extreme ambient temperature, which not only affects the cooling efficiency of the refrigeration system, but also has a negative impact on the service life of the compressor.
