Study on the heat-flow controllable heat exchanger (2nd report): Dehumidification in the greenhouse by the ventilation type dehumidifier with heat-flow controllable heat exchanger

A novel ventilation type dehumidifier with heat-flow controllable heat exchanger was installed on the wall of a greenhouse. Dehumidification and heat recovery experiments were conducted. The construction of the novel dehumidifier is simpler than that of the conventional dehumidifier with a compressor. It was found that the required input for the ventilation type dehumidifier was less than that of a conventional dehumidifier with compressor.
