Abstract: In an air-cooling-and-heating controlling system, individual variable air volume controllers send, to an air-cooler-and-heater controller, current cooling/heating requirement information for the controlled area that is controlled by that variable air volume controller. If there is a mixing of a cooling requirement and a heating requirement in the cooling/heating requirement information that is received, the air-cooler-and-heater controller establishes a cold air temperature setting value and a hot air temperature setting value that can handle the cooling requirements and the heating requirements at that time, to perform alternating switching of a supply air temperature setting value. If a variable air volume controller that requires heating is supplied cold air, it blocks the supply of air to the controlled area. If a variable air volume controller that requires cooling is supplied hot air, it blocks the supply of air to the controlled area.

Abstract: A measured value for a PMV within a living space is sent to a comfort efficacy evaluating device. Occupancy information (the current number of occupants N) in the living space is sent to the comfort efficacy evaluating device. The comfort efficacy evaluating device calculates a comfort index P as P=1.0?|PMV|/3, and this comfort index P is weighted by the number of occupants N at the time that the comfort index P was taken. In this case, if the number of occupants is relatively high, the weighting is high, and if the number of occupants is relatively low, then the weighting is low. Additionally, the weighted comfort index P is integrated over an evaluation interval, and thus integrated value, or a weighted average based on this integrated value, is used as a comfort efficacy index TP. An evaluation of the efficacy of energy conservation can be performed in the same way, taking into account the current occupancy of the living space.

Abstract: Individual VAV controllers send, to an air-conditioner controller, current cooling/heating requirement information for the controlled area that is controlled by that VAV controller. If there is a mixing of a cooling requirement and a heating requirement in the cooling/heating requirement information that is received, the air-conditioner controller establishes a cold air temperature setting value and a hot air temperature setting value that can handle the cooling requirements and the heating requirements at that time, to perform alternating switching of a supply air temperature setting value. If a VAV controller that requires heating is supplied cold air, it blocks the supply of air to the controlled area. If a VAV controller that requires cooling is supplied hot air, it blocks the supply of air to the controlled area.

Abstract: An indoor load is calculated from an indoor entropy of a controlled room, a supply air entropy of conditioned air that is supplied into the controlled room, and the amount of supply of the conditioned air that is supplied into the controlled room (indoor load=|indoor entropy?supply air entropy|×supply air flow rate). An overall efficiency for the air-conditioning system is calculated from the calculated indoor load and the total value for the amount of energy used by heat source equipment, heat source auxiliary equipment, and an air conditioner (the primary energy equivalent value thereof) (air-conditioning system overall efficiency=? indoor load/? (heat source energy usage amount+heat source auxiliary equipment energy usage amount+air conditioner energy usage amount)).

Abstract: A moisture exchange status monitoring device is provided. The moisture exchange status monitoring device is provided with: a temperature difference detecting portion; an evaluating portion; a setting value storing portion; and an evaluation result outputting portion. The temperature difference detecting portion detects a temperature difference ?t in the air on the treating side before and after passing through a desiccant rotor. The evaluating portion receives the temperature difference ?t from the temperature difference detecting portion and compares the temperature difference ?t to a setting value ?tth that is stored in the setting value storing portion, to evaluate the status of moisture adsorption of the moisture from the air on the treating side of the desiccant rotor. The evaluation result outputting portion outputs the evaluation result for the status of moisture adsorption, from the evaluating portion, as the monitoring result for the status of exchange of the moisture of the desiccant rotor.

Abstract: A dew-point temperature sensor is provided in a data center. In an air-conditioning controlling device, a lower limit value for a supply air temperature wherein there is no danger of the occurrence of condensation within a data center is calculated from a dew-point temperature (an inside dew-point temperature) that is measured by the dew-point temperature sensor, and a setting value for the supply air temperature and a setting value for the supply air flow rate into the data center the from the air-conditioning device are determined based on the calculated lower limit value for the supply air temperature. Note that a dew-point temperature for the exhaust air from within the data center, a dew-point temperature for the supply air into the data center from the outside conditioning equipment, or a dew-point temperature of the outside air may be used instead of the inside dew-point temperature.

Abstract: The present invention provides a dew point temperature sensor, detects a dew point temperature of supply air that is supplied to a dry room (i.e., the dew point temperature of process side dried air cooled by a cold water coil), and supplies such to a control apparatus as a supply air dew point temperature tdpv. When the supply air dew point temperature tdpv decreases, the control apparatus lowers the rotational speed of a regeneration side fan and a motor (i.e., a motor that drives a desiccant rotor). Furthermore, the dew point temperature of return air and the like may be detected instead of the dew point temperature of the supply air. In addition, the rotational speed of the regeneration side fan alone may be lowered. In addition, the present invention may be of a type that does not comprise the cold water coil or of a type wherein the return air does not return to the process side air.
