The server (3) can obtain weather report data (4) via a network such as the Internet. The server (3) includes a memory (storage unit) storing a plurality of operation control tables for determining a method of operation of the air conditioner (2); a control unit that selects an operation control table by using the weather report data (4); and a transmission unit (communication interface) that sends the operation control table selected by the control unit to the air conditioner (2).

Abstract: The air conditioner 1 includes an outdoor unit 10 and an indoor unit 30. The outdoor unit 10 includes an outdoor heat exchanger 16, a compressor 12, an outdoor fan 15, a temperature detector 23 for detecting a temperature of the outdoor heat exchanger 16, and a temperature detector 27 for detecting an outdoor temperature. The indoor unit 30 includes an indoor heat exchanger 33 and an indoor fan 32. The air conditioner 1 has a heating operation mode: that is, when the outdoor temperature reaches a predetermined first specified temperature or lower during a heating operation, the air conditioner 1 stops the heating operation and goes to standby, and thereafter, when the outdoor temperature reaches a temperature equal to or higher than a predetermined second specified temperature higher than the first specified temperature, the air conditioner 1 executes a defrosting operation and subsequently resumes the heating operation.

Abstract: When the outside air temperature is low, an air conditioner 1 performs a heating operation while a heating unit 2 performs a main heating operation. When the outside air temperature is high, the air conditioner 1 performs a main heating operation, and the heating unit 2 performs an auxiliary heating operation. While the air conditioner 1 performs a heating operation, the heating unit 2 is turned off before the room temperature reaches a set temperature. That is, the heating unit 2 is turned on for a longer time as the outside air temperature becomes lower. In this way, the heating unit 2 is operated under the situation to thereby supplement the heating capacity of the air conditioner 1, so that comfortable heating is performed.

Abstract: Provided is an air conditioner including: a heater control section (54) for carrying out duty control on a positive temperature coefficient (PTC) heater (55); and a current detecting section (53) for detecting a current value of the PTC heater (55). The PTC heater (55) starts to be driven at a predetermined duty ratio. When the current value detected by the current detecting section (53) takes a peak (P), a duty ratio increasing process of increasing the duty ratio of the PTC heater (55) by a predetermined amount is repeated until the duty ratio reaches to 100%.

Abstract: An integrated air conditioner that controls the operation of a water feed device according to the mode of use. The air conditioner includes a control section that determines whether or not exhaust heat from a condenser 3 is being released outdoors through an exhaust duct 7 according to whether or not an air intake duct 26 or an exhaust duct 7 is fitted, operates a water feed device 8 for leading drain wafer collected in the drain pan to the condenser 3 during both of a cooling operation and a dehumidifying operation if it determines that the heat to be released from the condenser 3 is being released outdoors, and operates the water feed device 8 during the cooling operation and stops the operation of the water feed device 8 during the dehumidifying operation if it determines that the exhaust heat from the condenser 3 is not being released outdoors.

Abstract: An electric heating module for a room air conditioning system and methods are presented in which the duty cycle of the electric heater banks are controlled to limit the inrush current during the startup phase of the heater or to supplement the heat generated by the heat pump when the heat capacity of the heat pump nears the heat loss of the room being heated.
