摘要： PURPOSE:To omit a humidifier of an air supply passage side necessary at the time of heating by installing a heater at this side of a moisture absorbing rotor at the time of heating, and operating a humidifier of a circulating air passage side. CONSTITUTION:A sensible heat exchanger 5 for heat exchanging the supply air with the circulating air is installed over an air supply passage la and a circulating air passage 1b. A heater 6 is installed between a fan 2 and a moisture absorbing rotor 4 at the passage 12. A regenerative heater 8 dries a moisture absorbing rotor 4 installed between the rotor 4 and the exchanger 5 at the passage 1b, and a humidifier 9 is installed between the exchanger 5 and a circulating air port 15. Thus, the heater 6 installed between the exchanger 5 and an air supply port 14 is transferred to this side of the rotor 4, and the rotor 4 is operated as a humidifying rotor at the time of heating, thereby using the humidifier 9 at the circulating air passage side as for both cooling and heating.

摘要： PURPOSE:To prevent the phenomenon of cavitation of a pump due to insufficiency of a refrigerant liquid by a method wherein motor operated valves controlling supply of a refrigerant to a heat exchanger are opened and the refrigerant liquid kept in heat exchangers is supplied onto the suction side of the pump, when an inlet temperature of a refrigerant gas carrying pipe becomes the temperature of liquefaction of the refrigerant or below at the time of heating. CONSTITUTION:When a system is switched over to a heating operation, a motor operated valve 6 is closed and a refrigerant passing through heat exchangers of fan coil units 2 and liquefied flows onto the suction side of a pump 5. When the pump 5 is driven then, motor operated valves 21 are opened automatically, a refrigerant gas produced by heating and evaporation in a heat exchanger 1 flows through a refrigerant gas carrying pipe 3 and passes through the heat exchangers of the fan coil units 2 and, on the occasion, the refrigerant liquefied by heat exchange is returned to the heat exchanger 1 via a refrigerant liquid carrying pipe 4. The motor operated valves 21 are controlled to open when an inlet temperature to the units 2 of the refrigerant gas detected by a temperature detector 7 becomes the temperature of liquefaction of the refrigerant or below.

摘要： PURPOSE:To simplify system structure by using a heat exchanger as a heat exchanger common for cooling and heating, and commonly using a conveying tube for supplying refrigerant liquid with a conveying tube for returning the liquid. CONSTITUTION:In the case of cooling, when a valve 6 is opened, a valve 7 is closed and a fan coil unit 2 is operated, refrigerant liquid cooled and liquefied by a heat exchanger 1 is passed through a conveying tube 3 and a heat exchanger of the unit 2. In this case, refrigerant gas vaporized by heat exchanging is returned to the exchanger 1 through a conveying tube 4, and again liquefied to be supplied to the unit 2 through the tube 3 to form a natural circulating cycle. In the case of heating, when the valve 6 is closed, the valve 7 is opened and a pump 5 is driven to operate the unit 2, refrigerant gas vaporized by the exchanger 1 is passed through the tube 4 and the unit 2. In this case, refrigerant liquid liquefied by heat exchanging is returned to the exchanger 1 through the tube 3 by the pump 5, and vaporized.

摘要： PURPOSE:To permit the removal of dust, bacteria and the like, which are generated in a fan coil unit, by a method wherein a fan is arranged at the upstream side of a heat exchanger while a filter is arranged at the downstream of the heat exchanger. CONSTITUTION:When a middle performance filter 5 is attached detachably to the vicinity of an air-conditioning air outlet port 42 and hot-water or cold water is passed through the coil of a heat exchanger 3, then, a fan 2 is driven and air-conditioning operation is started, air-conditioning air, cooled or humidified by passing through the heat exchanger 3, flows from the discharging port 11 of a main body casing 1 toward the conditioning air outlet port 42 of an outlet port main body 4. The conditioning air passes through the filter 5 before being sent out from the outlet port 42 into a room whereby dust, bacteria and the like, which are contained in the conditioning air, are removed by the filter 5.

摘要： PURPOSE:To obtain an air flow rate regulator in which an operation is smooth and which has a low cost. CONSTITUTION:A male threaded main shaft 3 is engaged with a female threaded rotary drive member 6 supported by a stationary base 2. An end of the shaft 3 is fixed to a center of an air flow rate regulating plate 4. An end of an auxiliary shaft 7 parallel with the shaft 3 is fixed at a position deviated from a center to the plate 4. Since the shaft 3 is disposed at a center of an apparatus, its operation becomes smooth. A large strength is not required at the shaft 7 merely by supporting the strength to the shaft 3, a weight of a movable part is reduced to simplify its structure, and cost of an entire apparatus can be reduced.

摘要： PURPOSE:To promote the heat radiation action of a heat-exchanging body on the heat radiation side to sufficiently bring out cooling capacity during cooling operation, in an air-conditioning device with a built-in heat transfer unit employing a Peltier effect element. CONSTITUTION:A heat transfer unit 1 is arranged in an inclined state and a fiber material 15 extending from a position in the vicinity of the lower end of the inclination in a state to cross an air flow passage 8 forming the heat radiation side of a Peltier effect element 2 during cooling operation is arranged. The fiber material 15 has draft properties and hydrous properties. Dew condensation water generated during cooling operation flows along the slop of the heat transfer unit 1 and permeates the fiber material 15. Air flowing through the air flow passage 8 on the heat radiation side during cooling operation is cooled by means of dew condensation water.

摘要： PURPOSE:To obtain a heat transfer unit in which a sufficient distance for heat insulation can be kept between two heat exchanging elements by a method wherein a good heat conductive spacer is provided at least either between a Peltier effect element and the heat absorption side heat exchanging element or between the Peltirer effect element and the heat release side heat exchanging element. CONSTITUTION:A Peltier effect element 9 is square thin plate having a side length of 40 mm and a thickness of 3 mm, and is laminated with a spacer 26 made a good heat conductive metal of copper or aluminum. And, the Peltier effect elements 9 are arranged in zigzag and held between a load side heat sink 10 and a heat source side heat sink 11. The spacer 26 is high in heat conductivity and is not so thick that the heat absorbing and releasing action of the element 9 is reduced. However, the spacer 26 maintains a sufficient distance for heat insulation between the load side heat sink 10 and the heat source side heat sink 11.

摘要： PURPOSE:To reduce the facility cost by reducing the system capacity of a cold/ hot water circuit by handling the peak load by two heat source circuits of refrigerant circuit and cold/hot water circuit and directly introducing the refrigerant in a condensing unit into a heat storing tank. CONSTITUTION:When operating in air conditioning mode in the daytime, a refrigerant circuit is formed between a condensing unit 2 and a first heat exchanger 5 by switching a 3-way valve 9. Under low load conditions, the operation is conducted only with heat supplied from a heat storing tank 3 to a second heat exchanger 6, and the water flow is controlled in proportion to the load by means of the valve control or inverter control of a pump 11. When the load increases and the heat supply from the storing tank 3 cannot meet the demand, or the remaining quantity of heat in the storing tank 3 becomes insufficient, the unit 2 is operated at its full capacity, and the operation is conducted with the heat exchanger 5 or heat exchangers 5, 6. As the refrigerant in the unit 2 is directly introduced into the heat storing tank 3, there is no need for a brine pump etc., the facility cost and operating cost are reduced, and the servicing becomes unnecessary.
