Piston compressor parallel unit
Piston-type parallel unit adopts semi-hermetic piston compressor, and automatically controls the working status of multiple compressors through pressure sensors, saving operating costs, and can be used in food, medicine, chemical, fruit storage and other industries.
Multiple compressors work together, with high reliability and hierarchical energy control. Advanced PLC control, support for remote monitoring, complete safety protection system, space-saving miniaturization design, and hierarchical energy control. Through the combination of multiple compressors, you can Obtain a combination of multi-level output power, which can achieve the best energy regulation for load changes, improve efficiency, and save energy. Reliability is high. Because there are multiple compressors, even if a single machine fails, other machines can continue to refrigerate, so you can rest assured. Safe operation, with a complete safety protection system such as high pressure, low pressure, oil pressure difference, overload, overheating, etc., to ensure normal operation under severe conditions of high temperature or low temperature.
The remote control unit adopts a special controller for parallel units, which can realize remote control, and can control the operation of all equipment in all cold storages in the office or control room. Space-saving and miniaturized design The unit has a reasonable structure design and a small footprint. The miniaturized design greatly saves the time required for installation and maintenance of the unit. It can be placed in the front and back of the house and on the roof. There is no need to set up a dedicated computer room and no full-time job. Operators on duty save operating costs. Economical operation According to temperature requirements, the pressure of the system is sensed by the pressure sensor, and the number of compressors is automatically controlled to start and stop according to the pressure, so that it is always in the best and most economical working state, which can greatly save operating costs.
Parallel units can determine the number of start-ups and the start-up time according to the heat load of the cold storage. When a cold storage is centralized, multiple compressors can work, so that the stored items can be reduced to the required temperature in the shortest time. In winter when the heat load is small or there are fewer items in the warehouse, one compressor can be used. The machine controls all warehouses.
