Heat recovery
H.Stars Group has been engaged in R&D of heat recovery technology and application, accumulated a lot of experience in thermal energy recycling, and has a national patent for heat recovery. Provide customers with free hot water during the project , cost and energy saving. It can reduce the heat pollution caused by condensation heat to the environment, and reduce the running cost and noise of the cooling tower.
Brief introduction of heat recovery technology
The heat recovery technology is an air-conditioning energy-saving patented invention. The principle is that when the unit is cooled, the heat originally discharged into the atmosphere can be recovered and converted into hot water, which can be used for living hot water, process heating. During heat recovery process, only the circulating water pump need to be installed, a large amount of free hot water is provided. At the same time, the cooling capacity of the unit is increased by about 5%, which is suitable for industrial production processes and commercial places with large demand.
Winter energy-saving device
In the transitional season and winter, the outdoor ambient temperature is lower than the process water temperature, taking advantage of the cold air outside to cool the process water without turning on the compressor. The dry cooler uses this principle to achieve the real non-compressor cooler. When the ambient temperature is lower than the process water temperature, the process water run through the interior of the dry cooler heat exchange tube. The fan is used to control the flow of outside cold air to cool the process water, and to ensure that the process water temperature meets the set requirements. It meets the requirements and saves 90% energy.
