52 Kw R410A Ultra-Low Temperature Variable Frequency Cascade High Temperature For Slaughter House

Principle of 150 kw Ultra-low temperature variable frequency cascade high temperature heat pump unit
A cascade heat pump start-stop control method, device, computer equipment and storage medium; the method includes: detecting the inlet water temperature of the cascade heat pump; controlling the primary compressor to start; after the primary compressor is turned on, if the inlet water temperature If the second constant temperature startup condition is met, the secondary compressor is controlled to be turned on according to the start-stop control rule; if the inlet water temperature meets the second constant temperature shutdown condition, the secondary compressor is controlled to be turned off according to the start-stop control rule; the primary compressor is controlled to be turned off; this application In the embodiment, by detecting the inlet water temperature of the cascade heat pump, the opening and closing of the primary compressor is controlled according to the inlet water temperature, and the opening and closing of the secondary compressor is controlled according to the inlet water temperature and the start-stop control rule; the existing primary compressor is avoided. The opening of the primary compressor and the secondary compressor are judged according to the inlet water temperature of the cascade heat pump, which may cause the problem of excessive high pressure of the primary compressor and realize the protection of the primary compressor.

A cascade heat pump operation method and system, the method includes: acquiring a current ambient temperature; comparing the current ambient temperature with a preset switching temperature; and switching between single-stage compression operation and cascade operation according to the comparison result. The operation mode of the cascade heat pump, the value of the preset switching temperature is determined according to the target ambient temperature that the cascade operation is consistent with the performance of the single-stage compression under the same heating target, and the single-stage compression operation mode is: The high temperature stage of the cascade heat pump operates independently, and the cascade operation mode is that the low temperature stage and the high temperature stage of the cascade heat pump operate simultaneously. Based on the technical solution of the present invention, the method enables the heat pump system to work in a higher-performance operation mode under different working conditions and temperatures, and improves the performance of the heat pump system for producing high-temperature hot water throughout the year.

The ultra-low temperature variable frequency cascade high temperature heat pump unit adopts the form of R410A low temperature stage and R134a high temperature stage system. Heat exchange for making hot water or heating. The ultra-low temperature cascade high temperature heat pump unit adopts DC frequency conversion technology, which has high heating energy efficiency. Temperature can be stable heating 75 ° C.
