Problems solved by technology

This increases energy consumption
[0005] Furthermore, in the pre-cooling / reheating type temperature control system, the output is offset by firstly pre-cooling by the cooler and then heating by the heater, therefore, if this output offset is not performed properly, energy will be increased consume

Abstract

A temperature control output branch unit D_MV_Temp outputs a controlled variable to a heating actuator Act1 when the controlled variable output MVT of a temperature controller PID_Temp is in a heating mode, and outputs it to a cooling actuator Act2 when the output MVT is in a cooling mode. A humidity control output branch unit D_MV_Hum outputs a controlled variable to a humidifying actuator Act3 when the controlled variable output MVH of a humidity controller PID_Hum is in a humidifying mode, and outputs it to the actuator Act2 when the output MVH is in a dehumidifying mode. A cooling output maximum value operation unit C_MAX gives whichever is larger of respective controlled variable outputs from the branch units D_MV_Temp and D_MV_Hum to the actuator Act2.

Description

technical field [0001] The present invention relates to a method of controlling temperature / humidity or temperature and a device for controlling temperature / humidity or temperature, which utilize heating actuators, cooling actuators or humidifying actuators in temperature / humidity control systems, or in temperature control In the system, the heating actuator is used as the main actuator and the cooling actuator is used as the auxiliary actuator, which can save energy. Background technique [0002] An air conditioning control system in a building and the like includes a cooler for cooling and a heater for heating. For added comfort, humidity is also controlled in many cases. To this end, the system also has a humidifier and performs temperature / humidity control by which both temperature and humidity can be controlled simultaneously. It should be noted that since the cooler has a dehumidifying function, no additional dehumidifier is required. Also, in baths with temperature...
