摘要： A reverse cycle refrigeration apparatus for air dehumidification is employed having an evaporator and a condenser and employing first and a second heat transfer coils for this purpose. Both coils are positioned in the air stream. In a first cycle the second coil functions as the evaporator for cooling and dehumidifying the air stream and accumulating frost and the first coil acts as the condenser, warming the cooled and dehumidified air stream and thawing frost having accumulated on it. In a second cycle the first coil acts as the evaporator, cooling and dehumidifying the air and providing the heat for defrost and the second coil acts as the condenser, thereby being defrosted. Dampers are provided for stopping air flow over the defrosting coil.

摘要： In a radiation type air conditioning system for cooling or heating fluid such as air or refrigerant through heat exchange and supplying the cooled or heated fluid into a radiant panel to radiatively cool or heat a room, the air is cooled by a heat exchanger (evaporator), and the cooled air is supplied onto the radiation face of the radiant panel by a fan to prevent dew condensation on the radiation face of the radiant panel. If the air which is cooled and dried by the evaporator is heated by a heater when it is supplied onto the radiation face of the radiant panel, the dew condensation preventing effect can be enhanced. Further, plural through holes are formed in the radiation panel and the cooled air is blown out onto the radiation face through the through holes, so that the dew condensation preventing effect can be enhanced.

摘要： Air drawn in by a fan 4 is cooled by evaporator coils 2 and re-warmed by a condenser 3. A microcontroller MC and sensor S reads the temperature of the incoming air at regular intervals, e.g. once every minute, and controls a compressor 1 to operates in successive run periods, during which the evaporator 2 removes moisture from the air, separated by defrost periods in which the compressor is switched off so that warm incoming air melts any ice on the evaporator. The temperature at the start of a run period determines the duration of the respective run period, and the temperature at the end of a run period determines the length of the following defrost period. The length of the run period is constant at low temperatures but increases to a longer constant period at higher temperatures. The length of the defrost period is a maximum close to freezing point, but is reduced by decreasing increments as air temperature increases. At higher temperatures the dehumidifier operates continuously with no defrost.

摘要： Apparatus for providing integrated control of a space cooling system is disclosed. The apparatus receives inputs from a plurality of temperature sensors, including a temperature sensor for measuring evaporator superheat, space temperature and compressor discharge temperature. The control apparatus incrementally adjusts the position of the cooling system expansion valve to regulate evaporator superheat and compressor discharge temperature and cycles the outdoor condenser fan on and off to raise condenser pressure in response to a low condenser pressure condition. In one embodiment, the cooling system includes a plurality of evaporators and a corresponding plurality of controllers electrically interconnected in a series loop for controlling the expansion valves and defrost heaters associated with the respective evaporators. One of the controllers functions as a master controller and receives inputs from the space temperature sensor and the compressor discharge temperature sensor as well as from the temperature sensors associated with the corresponding evaporator. The master controller activates and deactivates the cooling cycles in response to the inputs from the space temperature sensor. Both the master controller and each slave controller separately control the corresponding expansion valve and defroster. The master controller also initiates the system defrost cycle. However, once the defrost cycle is initiated, each slave controller controls the defrost cycle for its corresponding evaporator.

Whether the initial quantity of supplemental heating elements provided is insufficient or excessive is determined. At least one of the supplemental heating elements is deactivated if the initial quantity of supplemental heating elements being provided is excessive. At least one of the supplemental heating elements is activated if the initial quantity of supplemental heating elements being provided is if the initial quantity of supplemental heating elements being provided is insufficient, and at least one additional supplemental heating element is available.

摘要： An air conditioning apparatus includes an air duct having an inlet and an outlet supplying conditioned air, and an air conditioner for cooling and heating air using a refrigeration cycle. In the refrigeration cycle, the air conditioner includes a first heat exchanger, a second heat exchanger disposed on a downstream side of the first heat exchanger, and a compressor. The air conditioner selectively operates in a cooling mode where cool air cooled by the first heat exchanger is supplied through the outlet of the air duct, in a heating mode where hot air heated by the first heat exchanger is supplied through the outlet of the air duct, and in a dehumidifying mode where air cooled by the first heat exchanger and subsequently heated by the second heat exchanger is supplied through the outlet of the air duct. In order to prevent frosting of the heat exchanger functioning as an evaporator, a temperature sensor just downstream of the first heat exchanger in conjunction with a timer and control arrangement increase the evaporator temperature if it is below a set lower limit for a set period of time.CROSS REFERENCE TO RELATED APPLICATION

摘要： A heat exchanger in combination with two duct system for bringing in relatively cold outside air into an enclosure while exhausting relatively warm room air from the enclosure. The heat exchanger is positioned so as to recover heat from the exhaust air into the incoming cold fresh air. A valving system switches the incoming cold air with the warm exhaust air in the flow paths of the heat exchanger. This solves the problem of moisture from the exhaust air condensing on the walls of the ducting system for the exhaust air.
