The invention relates to an industrial cold and hot balance unit system and a control method of the industrial cold and hot balance unit system, and relates to an energy recycling system for a combined heating and refrigeration system and a control method of the energy recycling system. The industrial cold and hot balance unit system comprises a cold and hot balance unit, a cold air subsystem, a hot air subsystem, a hot water subsystem and a control device, wherein the cold and hot balance unit comprises a refrigerant circulation loop with the cold and hot balance configuration and a refrigerant circulation loop with the heat pump configuration, a control device has control over configuration switching of the refrigerant circulation loops through an electric three-way valve, a hot water condenser and a heating medium water pump form a heating medium water circulation loop sequentially through a heat storage water tank and a combined air cabinet hot water coil pipe, and a cold water evaporator and a refrigerant water pump form a refrigerant water circulation loop through a combined air cabinet cold water coil pipe. The cold and hot balance unit is controlled through the control device, balance transfer of cooling and heating loads is achieved, the cooling and heating load requirement and the temperature and humidity requirement of workshops are met, effective balance of the cooling and heating loads is ensured, the equipment utilization rate is high, the cost is low, energy is effectively utilized, and energy is sufficiently saved.
Description
technical field [0001] The invention relates to an energy recovery and utilization system for a combined heating and cooling system and a control method thereof, in particular to an industrial cooling and heating balance unit system and a control method for the system. Background technique [0002] Energy consumption in my country's industrial sector accounts for about 70% of the country's total energy consumption, and the average unit energy consumption of major industrial products is about 30% higher than the international advanced level. In addition to factors such as relatively backward production technology and unreasonable industrial structure, the low utilization rate of industrial waste heat is an important reason for high energy consumption. my country's energy utilization rate is only about 33%, which is about 10% lower than that of developed countries, and at least 50%. Industrial energy consumption is directly discarded as waste heat in various forms. Therefore, ...
