A house air conditioning system that operates with outside air. The air conditioning system closes the house and uses air conditioning, when the outside temperature is lower than the inside house air temperature the air conditioning system is turned off, the house or building is opened to the outside and the cooler outside air is drawn through the house using fans. In the morning, before sunrise, the fans will draw outside cool air in from the outside to cool the thermal mass of the house and then closes the house as the outside air heats to trap the cool air within the house to delay air conditioning operation and reduce the overall amount of AC runtime energy required to cool the house. This system can also operate in reverse to heat the home. The system uses multiple sensors and control mechanism to ensure optimal energy savings.

An adaptive control device (77) and method (102-108) for control of the operation of an actuator (72), and particularly thermally-powered actuator (72) of the type used in a variable-air-volume diffuser (71). The preferred adaptive control device is an expert system circuit which controls a heater (74) provided on a thermally-powered actuator (72) to implement an adaptive process (102-108) in which a sensed variable, such as room air temperature, is driven toward a target temperature control range (±0.25° F.). Most preferably, the process steps (106) include driving the room air temperature toward a gross (broader) temperature control range (±1.0° F.) by moving a diffuser damper assembly (80) to a substantially fully open or substantially fully closed position. Thereafter, and while inside the gross temperature control range, the process steps (107, 108) include adjustments to the position of the damper assembly (80) are made only when a sensed parameter, preferably the supply air flow rate, is in a stable condition. Most preferably, the damper (80) is temporarily "kicked" farther open or farther closed than necessary, to minimize hysteresis effects, and then adjusted to a posiiton which tends to drive the room air temperature into the narrower, targeted temperature control range.

The energy-saving control method for the auxiliary temperature-reducing heat-exchange device comprises the following steps of: a, selecting to enter an energy-saving heat-exchange mode; b, measuring the temperature of the indoor air and the temperature of the outdoor air, and calculating the temperature difference between indoors and outdoors; and c, finding the energy efficiency ratio of the auxiliary temperature-reducing heat-exchange device during the temperature difference between indoors and outdoors according to a temperature difference-energy efficiency ration chart of the air conditioner, and starting or shutting the auxiliary temperature-reducing heat-exchange device. The method can accurately judge the most energy-saving starting / stopping time of the auxiliary temperature-reducing heat-exchange device, thereby realizing high efficiency and energy conservation; at the same time, the method can ensure that the auxiliary temperature-reducing heat-exchange device better adapts to different air-conditioning equipment and is matched with the air-conditioning equipment for using; and the method strengthens the adaptability and the universality of the auxiliary temperature-reducing heat-exchange device.
