Abstract

The invention discloses a cooling and heating continuous supply system and a cooling and heating continuous supply method for recycling and recovering waste heat from cold equipment, and belongs to the field of cold and heating continuous supply systems and cooling and heating heating methods for factory production. It includes a water storage tank, an auxiliary heating pipeline, a waste heat recovery pipeline, and a cooling pipeline; the auxiliary heating pipeline includes a first water pump and an auxiliary air heater connected sequentially through pipelines; the waste heat recovery pipeline includes The second water pump, the heat exchange device, and the air energy transducer, the water inlet of the second water pump is connected to the water storage tank, and the water outlet of the air energy transducer is connected to the water storage pool; the cooling pipeline includes a third water pump connected in sequence through pipelines ,Cooling Tower. The invention utilizes the plate heat exchanger to exchange the heat energy of the equipment into the water to form hot water, and transfers the heat energy in the hot water to the fresh air through the air energy transducer, and the fan blows the hot air to the heat-consuming equipment to use heat, and at the same time can provide The cold air is used for the cooling equipment; to realize the all-weather constant temperature water supply, save energy and reduce consumption, and use one thing for three purposes.

Description

technical field [0001] The invention relates to a continuous heating and cooling supply system and a continuous heating and cooling supply method for factory production, in particular to a continuous heating and cooling supply system and a continuous heating and cooling supply method for recycling waste heat from refrigeration equipment. Background technique [0002] There are many ways to heat the equipment in the factory, including electric heating, steam heating, oil heating, etc. Due to the trend of environmental protection requirements, all enterprises are looking for ways to save energy and reduce emissions. Many manufacturers are trying to find ways to save energy: for example, use More energy-efficient heating methods, waste heat recovery, etc. However, the hot water generated after refrigeration is only directly cooled by a very simple cooling tower, and this part of heat energy is directly discharged into the air, which has huge invisible energy waste.
