OPERATION CONTROL FOR AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To enhance the reliability while incorporating the comfortableness and economy by providing a thermistor for detecting outdoor and indoor air temperatures and a driving motor for operating or stopping entire heat exchanging rotors. SOLUTION: An entire heat exchange rotors 1 is rotated by driving it by a rotor driving motor 2 according to the command from a control case 5. A compressor 13 for constituting a refrigerating cycle together with a direct expansion coil 12 is also operated or stopped according to a command from the case 5. The case 5 can recognizes the outdoor and indoor air temperatures by outdoor and indoor temperature thermistors 3, 4. Since the air temperature introduced to the coil 12 is decided by the indoor circulating temperature, outdoor suction temperature and the temperature exchange efficiency of the rotor 1, and hence it can be calculated by the case 5. Accordingly, it can judge from the outdoor and indoor air temperatures whether the heating or cooling of the coil 12 by the operation of the compressor 13 is needed or not or whether the heat recovery of the rotor 1 is needed or not to obtain the comfortable indoor diffusing air temperature.
