Design of Drying, Dehumidification and Heat Recovery System

With the rapid development of manufacturing industry, many products require drying and dehumidification treatment during the production process. These processes not only require efficient moisture removal, but also require maintaining the characteristics and quality of the material. Traditional drying and dehumidification methods often consume high energy and may have adverse effects on the environment, such as emitting greenhouse gases and other pollutants.

By adopting efficient heat recovery technology, waste heat can be maximally recovered and reused to reduce energy consumption. Heat recovery technology has been widely applied in multiple industries to improve energy efficiency and reduce operating costs. But in the field of drying and dehumidification, the potential of this technology has not been fully tapped. We customize and develop a heat recovery system that suits your specific production needs and on-site conditions. We carefully design the system layout for you to ensure minimal loss of thermal energy during conversion and transmission. Welcome to inquire via email.

Energy saving scheme for heat recovery of central air conditioning system

In the operation of central air conditioning systems, we can adopt high-efficiency heat exchangers for energy-saving renovation plans, and can choose plate heat exchangers or microchannel heat exchangers with high heat transfer efficiency and low fluid resistance. Our heat exchanger has a larger heat transfer area and more efficient heat transfer performance, which can reduce energy consumption under the same heat transfer conditions. Install a waste heat recovery device in the central air conditioning system to recover and reuse the emitted heat. It can also be combined with heat pump technology, which is an efficient way of transferring heat energy by consuming a small amount of electricity or fuel energy to transfer the heat from a low-temperature heat source to a high-temperature heat source. The application of heat pump technology in central air conditioning systems can improve the coefficient of performance (COP) of the system and reduce energy consumption.
