Working Principles

Heat recovery is based on heat exchange. Equipment such as heat exchangers, heat pumps and heat pipes enable energy transfer between different media and the upgrade of heat quality.

Heat Exchangers

Through structures such as plate and shell-and-tube, heat is transferred between hot and cold media. Plate heat exchangers have high heat transfer efficiency, small footprint and easy maintenance, commonly used in HVAC and process flows.

Heat Pump Systems

Using the refrigeration cycle (compressor, evaporator, condenser, expansion valve) to upgrade low-temperature heat to high-temperature heat, suitable for heating and process heating. The COP (coefficient of performance) of heat pumps is usually greater than 1, featuring high efficiency and energy savings.

Heat Pipe

Rapid heat transfer inside the pipe via phase change and capillary action. It features high thermal conductivity and simple structure, widely used in electronics cooling and waste heat recovery.

Waste Heat Power Generation (ORC)

The Organic Rankine Cycle uses low-boiling-point working fluids (such as R245fa) to expand in a turbine to drive a generator, converting medium and low-temperature waste heat into electricity.
