摘要： PURPOSE:To make it possible for sure to splash the water condensate even under a high wind pressure by providing a water conduit which has its outlet section in a liquid tank at the lower section of a slinger ring and providing a flange round the outer circumference of the liquid tank. CONSTITUTION:The water condensate that is obtained from an indoor side heat exchanger flows in a water conduit 4, and it is supplied to a water tank 6 through a net 20 or many minute holes 21. The net 20 keeps dusts of relatively large diameters from entering the inside of the water conduit 4, and, further, even when the meshes of the net 20 are clogged, the water condensate is supplied to the water tank 6 through the minute holes 21 formed in the surface of the water conduit 4. When the water level in the water tank 6 becomes high, the water condensate is stirred by a slinger ring 5. During this stirring water drops attached to the end faces of the slinger ring 5 fly in water splashes through the space between the outdoor side heat exchanger 1 and a heat radiation cover 3, and part of the splashes evaporate to absorb the latent heat, thus heightening the capabilities of the heat exchanger to transfer heat. Furthermore, on the bottom face 10 of the liquid tank, many pleats 13 are formed to increase the frictional force between the water condensate and the bottom face 10 for reducing the amount of over-flow.

摘要： PURPOSE:To prevent the shortcircuiting between the suction air and the exhaust air on the outdoor side from occurring through a strucutre wherein a gap is provided between the exhaust outlet side of a condenser and a condenser cover to cover the condenser in an air conditioner. CONSTITUTION:A minute gap 10 with the magnitude giving no disturbance to the air supply to a condenser 2 is formed between a condenser cover 7 and the condenser 2. The outside air taken in through a suction port 8 provided at the back of an air conditioner enters in the condenser cover 7, is blasted against the condenser by means of an outdoor blower 4 for heat-exchanging and finally exhausted from an exhaust port 9. At this time, some portion of the outside air taken in the condenser cover 7 is exhausted throught he minute gap 10 at high air speed without being heat-exchanged. Because said outside air exhausted through the minute gap causes to develop the cleavage between the suction air and the heat-exchanged exhaust air, resulting in enabling to prevent the shortcircuiting or the phenomenon of sucking the heat-exchanged air again from occurring.

摘要： PURPOSE:To enable a comfortable heating with less variation of room temperature to be performed by a method wherein a heat exchanger, a blower, a electrical appliances and a hot water valve are provided and at the same time means for controlling a degree of opening of the valve is provided. CONSTITUTION:An air conditioner 31 is operated such that a degree of opening of a flow controlling valve 35 in a heat exchanger 32 is increased by a stepping motor 35-1 to increase a flow rate of hot water in case that an actual room temperature is substantially low in respect to a predetermined temperature of a room temperature adjustor 40 in response to a preference of a user and then a flow rate of hot water is increased, a heating capability is increased and the room temperature can be approached rapidly to the predetermined temperature. In case that the room temperature reaches the predetermined temperature, a degree of opening of the flow rate controlling valve 25 is decreased, thereby a flow rate of the hot water is reduced to decrease the heating capability, resulting in that the room temperature is not so changed without substantially exceeding the predetermined temperature to perform a comfortable heating. When a flow rate of hot water in the heat exchanger 32 is controlled to be low, a rotational speed of a blower 37 is decreased and a temperature of hot blown air of the air conditioner 31 is not so decreased and a comfortable heating is assured.

摘要： PURPOSE:To keep the water level below the lower section of the vanes of a propeller fan lower than the propeller fan vane and prevent water splashing by providing a water splash stopping section which encircles the flow direction of condensed water. CONSTITUTION:A crank-shaped board 15a is spot-welded to the lower section of the cover 15 of a condenser so that it will contact the bottom face of a base 14. The board 15a shuts the condensed water in front of a propeller fan 16. The water level 17 of the condensed water on the left side of the board 15a is higher than the lowest point D of the vane 16a of the propeller fan 16, but the water level of the condensed water at the section which is surrounded by a condenser cover 15 and the board 15 stays lower than the lowest point D at a position below the lowest point D of the vane 16a, and draws a curve which gradually becomes higher along the direction of the rotation of the propeller fan 16. Accordingly water splashing by scooping up the condensed water by the vane 16a does not occur, and there is no need to install a water splash stopping board.
