Abstract

Abstract

A dual cooling source dehumidifier with exhaust heat recovery function was proposed, which recovers the cooling capacity of indoor exhaust for fresh air cooling. The dehumidification performance was experimentally investigated, along with the effects of various air volumes and water supply temperatures. The results show that under the conditions of a water supply flow rate of 1.7m³/h, compressor power of 0.8 kW, water supply temperature of 13 ℃, and air flow rate of 350 m³/h, the moisture content at the air supply outlet can reach 7.6 g/kg in the fresh air dehumidification mode, and 7.4 g/kg in the indoor circulation dehumidification mode can reach g. Reducing the air volume or lowering the water supply temperature will improve the dehumidification performance of the dehumidifier.
