(Conventional technology and its problems) Generally, an air conditioner refers to a device that sends cooling or heating air to a living space, that is, an air-conditioned area, and maintains the air-conditioned area in a comfortable temperature and humidity environment. The lower the humidity during summer cooling, the more comfortable the room, and the higher the humidity during winter heating, the more comfortable the room. .

However, lowering the cooling temperature or increasing the heating temperature in order to adjust the humidity has the adverse effect of causing the air-conditioned area to be too cold or too hot. The so-called so-called so-called "cooling" is sometimes used to cool the dehumidified air to the optimum temperature by heating the dehumidified air in the opposite direction, and to mix the humidified air with the low-temperature outside air to the optimum temperature during heating. Although re-heat treatment is performed, equipment for re-heating and a heat source are required during cooling, which is uneconomical.At the time of heating, it is mixed with low-humidity outside air. And the humidity changes greatly each time the temperature is adjusted.

(During cooling operation) Flow cold water through the heat exchange coil 5 in the air conditioner 8 main body.
When driving the blower 7 to start the cooling operation, since the inlet 8 1 intake external air of the main body becomes negative, external air inlet of the casing 1
1 1 outside air is sucked from entering the casing. When the damper 3 keep the fully closed state, entering outside air enters the inlet 81 intake ambient air of the main body through the external air supply port 1 2 through the first communication passage 1a of the heat exchange element 2, penetrates into the body I do. Outside air enters the body is by connexion cooled heat exchanger coil 5, whereby the dehumidified is blown out from the air blowing ports 8 2 as cooling air, through the inlet 1 3 intake feed air is connected to the air blowing port 8 2 penetrate into the casing 1, when leaving the damper 4 is fully closed, the invading cooling air aerodrome flows through the second communication passage 1b of the element 2 through connexion blower opening 1 4, an air outlet 1 4 The air is blown out from the air outlet to each air-conditioned area through an air duct connected to the air-conditioner. In the continuous process of taking in the outside air and blowing the cooling air, the outside air that has entered the casing 1 cools the cooling air passing through the second communication passage 1b while passing through the first communication passage 1a of the heat exchange element 2. The cooling air is heated by depriving the heat of the outside air. In other words, heat is exchanged between the outside air and the cooling air via the heat exchange element 2. Even if the cooling temperature is lowered to increase the dehumidifying capacity, the heat treatment is performed again by this heat exchange. Cooling air of an appropriate temperature is sent into each air-conditioned area.

If it is desired to increase the temperature of the cooling air during the cooling operation, the damper 3 of the bypass passage 1c on the outside air side is opened to increase the supply amount of the outside air that is not pre-cooled, thereby increasing the temperature of the cooling air to be blown out. If it is desired to lower the temperature of the cooling air, the temperature of the cooling air to be blown can be reduced by opening the damper 4 on the blast air side and increasing the amount of the cooling air that does not pass through the heat exchange element 2. Therefore, cooling air at a desired temperature can be obtained by adjusting the degree of opening of the dampers 3 and 4.

(During heating operation) When hot water is supplied to the heat exchange coil in the air conditioner body and the blower is driven to start the heating operation, the dampers 3 and 4 may be in the fully closed state as in the cooling operation described above. Heat exchange is performed between the outside air and the heating air, the outside air is preheated, and the heating air is cooled.

In other words, even if the heating temperature is set high to increase the humidifying capacity of the humidifier 6, re-heat treatment is performed by this heat exchange, and appropriate-temperature air is sent to each air-conditioned area. This can be performed by adjusting the opening of the dampers 3 and 4 in the same manner as during operation.

As described above, according to the method for controlling the reheat temperature of an air conditioner according to the present invention, outside air can be used as a heat source for reheat treatment during cooling. It is economical because it does not require equipment such as a heating coil for reheating and a heat source as in the reburning method, and is pre-cooled to the outside air, so that cooling efficiency can be increased and energy loss can be reduced. At the time of heating, heating air only exchanges heat with the outside air and does not mix with the outside air.Therefore, the humidity may drop due to mixing with the outside air as in the conventional method. Without the disadvantage that sufficient humidity can be obtained and the humidity changes greatly each time the temperature is adjusted, and because the outside air is preheated, the heating efficiency and the humidification efficiency can be increased and the energy loss can be reduced. Less As it can Rukoto, in which very large effect as a method for the re-heat treatment and reheat temperature control of the air conditioner, may provide an advantage.
