CONSTANT TEMPERATURE AND HUMIDITY SYSTEM CONTROL METHOD USING AN INDIRECT HEAT EXCHANGE

摘要

Provided is a method for controlling a constant temperature and humidity system using an indirect heat exchanger. The method allows the constant temperature and humidity system to be controlled based on a value obtained by comparing a measured outdoor air (OA) dry-bulb temperature or wet-bulb temperature with a preset indirect heat exchanger control set value by dividing a mode into a wintertime mode and a summertime mode. In addition, the method can prevent cross-contamination by indirectly performing heat exchange between indoor air and outdoor air using the indirect heat exchanger, maintain constant temperature and humidity in a room with little energy all year round, and improve energy efficiency by controlling the air temperature using evaporative latent heat of latent heat water injected into the indirect heat exchanger by a structure in which the heat exchange between outdoor air and indoor air is efficiently performed, thereby reducing energy consumption. The method can be economical to reduce operational costs because an operation is efficiently performed according to the measured OA dry-bulb temperature or wet-bulb temperature.
