Problems solved by technology
[0002] In the existing factory production environment, there are many cold sources that need to obtain heat to heat up, such as the liquefied gas output from the low-temperature liquefied gas tank, etc., and there are also heat sources that carry a large amount of heat that need to be recovered, such as boiler cooling water, Boiler exhaust gas, etc.; on the other hand, the refrigeration system and dehumidification system installed in the factory building also consume a lot of energy; various influences prevent the energy utilization rate of the factory from being further improved
[0003] In the process of raising the temperature of the existing cold source, the cold source such as liquefied gas is generally exchanged with the environment through an open-frame heat exchanger to achieve temperature rise. During the heating process, a large amount of cold energy is emitted to the environment and cannot be effectively used; Heat sources such as flue gas and cooling water produced by factory boilers will also take away a lot of heat and dissipate it to the environment, causing a lot of heat to be wasted

The invention discloses a cold-and-heat comprehensive utilization system. The cold-and-heat comprehensive utilization system comprises a heat exchanger, a heat exchanging device, a cold source and a heat source, wherein the heat exchanger is connected with the cold source; the heat exchanging device is connected with the heat source; and the heat exchanger and the heat exchanging device can enablethe heat of the heat source to be transferred to the cold source. According to the cold-and-heat comprehensive utilization system, the cold source and the heat source in the plant can be comprehensively utilized, and the energy consumption of cold energy recovery and heat energy recovery is reduced.
Description
technical field [0001] The invention relates to the field of medium circulation systems, in particular to a cold and heat comprehensive utilization system. Background technique [0002] In the existing factory production environment, there are many cold sources that need to obtain heat to heat up, such as the liquefied gas output from the low-temperature liquefied gas tank, etc., and there are also heat sources that carry a large amount of heat that need to be recovered, such as boiler cooling water, Boiler exhaust gas, etc.; on the other hand, the refrigeration system and dehumidification system installed in the factory building also consume a lot of energy; various influences prevent the energy utilization rate of the factory from being further improved. [0003] In the process of raising the temperature of the existing cold source, the cold source such as liquefied gas is generally exchanged with the environment through an open-frame heat exchanger to realize the temperat...
