Heat reclaim ventilation HRV design guide2HRV Features2-2Energy Saving2-2-3Night time free cooling operationAutomatic heat purge function at night12The nighttime free cooling is an energy-conserving function which works at night when the air conditioners is off, reducing the cooling load in themorning when the air conditioner is turned on. This is mainly for rooms that contain office equipment, which raises the room temperature. Nighttime free cooling only works during cooling and when connected to Building Multi or VRV systems. Nighttime free cooling is set to “off” in the factory settings; so request your dealer to turn it on if you intend to use it.40(a) Outside temperature(a)(b) Indoor temperature(c) Set temperature3020(b)OFF(d) Operating state of Air conditioner(c)ON(e) Operating state of Total heat exchangerOFF(e)Nighttime free cooling operationOFF(d)Operating state Temperature (ºC)Operation image22:0024:00(time)Following morningExplanation of nighttime free cooling operation imageThe unit compares the indoor and outdoor temperatures after the air conditioning operation stops for the night. If the following conditions are satisfied,the operation starts, and when the indoor temperature reaches the air conditioning setting, the operation stops.Conditions2the indoor temperature is higher than the air conditioning setting and3the outdoor temperature is lower than the indoor temerature.If the above conditions are not satisfied, reevaluation is made every 60 minutes.NOTEThe Nighttime free cooling operation works when the HRV unit is off. Therefore, it is not possible to stop the night purge operation, though theforced off is input from the optional controllers for centralized control.Test runAfter completing the installation of the system, check again to make sure that no error was made in wiring or switch setting on the printedcircuit boards of the HRV units.Then, turn on the power of the HRV units. Refer to the manual of the remote controller of each unit (remote controller for air conditioner, central controlunit, etc.) for conducting a trial operation.6 Ventilation Heat reclaim ventilation
