摘要： An air conditioning apparatus for an electric vehicle includes an electrically-driven compressor. A desired temperature is set which relates to one of a temperature of air discharged into a vehicle interior and a temperature within the vehicle interior. Detection is given of a temperature related to a heat exchanger. An inverter connected to the compressor is operative for driving the compressor at a variable speed corresponding to a desired rotational speed. A target temperature related to the heat exchanger is calculated in response to the desired temperature. Calculation is given of a difference between the detected temperature and the target temperature. Also, calculation is given of a variation in the detected temperature for every given period. A corrective rotational speed is calculated from the temperature difference and the temperature variation for every given period. Calculation is given of a sum of a current desired rotational speed of the compressor and the corrective rotational speed for every given period. The calculated sum is set as a new desired rotational speed of the compressor for every given period. The inverter is informed of the new desired rotational speed of the compressor.

摘要： In a multiroom air-conditioning apparatus, refrigerant flow between plural outdoor side units is controlled so that abnormality (lack or excess) of refrigerant amount in an outdoor side unit in operation is redressed. For example, when surplus refrigerant exists in an outdoor side unit, the refrigerant flow is so controlled that the surplus refrigerant is pushed out (flow out) into an outdoor side unit in non-operation. In addition, the output of the air-conditioning apparatus is smoothly variable (controllable) in accordance with an air-conditioning load over the whole air-conditioning load range from the minimum (zero) load to the maximum load.

摘要： A method and apparatus for improved latent heat extraction combines a run-around coil system with a condenser heat recovery system to enhance the moisture removing capability of a conventional vapor compression air conditioning unit. The run-around coil system exchanges energy between the return and supply air flows of the air conditioning unit. Energy recovered in the condenser heat recovery system is selectively combined with the run-around system energy extracted from the return air flow to reheat the supply air stream for downstream humidity control. A control system regulates the relative proportions of the extracted return air flow energy and recovered heat energy delivered to the reheat coil for efficient control over moisture in the supply air flow. Auxiliary energy in the form of electric heat energy is further added to the recovered heat energy for additional reheat use.

摘要： A method and apparatus to recover energy from used or foul air and to return the energy into fresh air to reduce the energy input to a ventilation system. Ventilator apparatus is adapted to maintain fluid flow through a first heat exchanger, positioned in a fresh air passage, and through a second heat exchanger, positioned in an exhaust passage, at a controlled rate to afford maximum or controlled heat transfer efficiency for pre-cooling or pre-heating fresh air drawn into the system. Control apparatus is provided to maintain flow of fluid through the heat exchangers such that the sum of the mass flow of fresh air times the specific heat of the fresh air, plus the mass flow of the exhaust air times the apparent specific heat of exhaust air, is equal to two times the mass flow of fluid times the specific heat of the fluid.

摘要： In an automobile air-conditioner comprising a compressor with variable discharge capacity for compressing a refrigerant, an outlet temperature sensor for sensing an outlet temperature at an outlet of at least one of a heat sink and a radiator, a room temperature sensor for sensing a room temperature inside the automobile, an outside air temperature sensor for sensing an outside air temperature outside the automobile, and a room temperature setting unit for setting the room temperature to a desired temperature, a first arithmetic operating unit carries out an arithmetic operation according to at least the room temperature, the outside air temperature, and the desired temperature, to obtain a target temperature. A second arithmetic operating unit predicts the rotation speed of the compressor with a predetermined feed-forward arithmetic expression to obtain a predicted rotation speed. A third arithmetic operating unit carries out an arithmetic operation with an arithmetic feedback control expression including the predicted rotation speed and a deviation between the target temperature and the outlet temperature to obtain the rotation speed of the compressor. The compressor is controlled in accordance with the rotation speed calculated by the third arithmetic operating unit.

摘要： A controller for a climate control system has a relative humidity sensor as well as a dry-bulb temperature sensor within the enclosure. The humidity value is used in conjunction with the dry-bulb temperature to generate an enthalpy error signal which is a function of both the dry-bulb temperature and the relative humidity values. This permits robust control of both enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. Instead of using a sensor which directly measures the enthalpy, the enthalpy can be synthesized from the relative humidity and dry-bulb temperature within the enclosure. Alternately, the sensed and set point enthalpy values can be synthesized from any two thermodynamic properties of the moist air within the enclosure.
