The invention provides a DC frequency conversion refrigeration equipment and its refrigeration system. The refrigeration system includes a condenser, a liquid receiver, an evaporator and a DC frequency conversion compressor, and the condenser, liquid storage device, evaporator and DC frequency conversion compressor are connected. The pipeline system also includes a control system, the control system includes a control board and a temperature controller, the DC variable frequency compressor is powered by the DC variable frequency compressor drive board, and the control signal of the control board controls the DC variable frequency compressor operating frequency. The refrigeration system is controlled by an intelligent control panel to monitor multiple parameters such as the environment of the cold storage, condensing pressure, and working medium temperature, and uses feedback control to control the speed of the condenser fan to adaptively adjust the condensing pressure so that the condensing pressure is consistent with the environment. Adaptation, automatic control is realized and the energy saving effect is good, which is conducive to maintaining a stable temperature and humidity state in the cold storage, ensuring the quality of stored items, and reducing manual operations.
Description
technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a DC frequency conversion refrigeration equipment and a refrigeration system thereof. Background technique [0002] At present, frequency conversion technology is relatively common, but the frequency conversion technology applied to cold storage refrigeration equipment needs to be improved. Some frequency conversion refrigeration equipment used in cold storage cannot realize automatic and continuous frequency conversion adjustment, and the equipment frequently stops and restarts automatically, resulting in high energy consumption of the equipment. And the refrigeration efficiency is low, which is not conducive to maintaining the stable temperature and humidity state of the cold storage and the quality of the frozen and refrigerated items. At the same time, the freezing and refrigeration equipment needs to adjust the working state of the equipment according to the temperatur...
