Description

Air Conditioner {AIR CONDITIONER}

The present invention introduces indoor air by an indoor fan, performs heat exchange between the refrigerant passing through the interior of the indoor heat exchanger and the indoor air passing through the outer surface of the indoor heat exchanger, thereby adjusting air after heat exchange. It relates to an air conditioner that discharges the room.

In a typical separate air conditioner, an outdoor heat exchanger disposed in an outdoor unit and an indoor heat exchanger disposed in an indoor unit are connected in a refrigerant pipe to control each heat exchanger to function as a condenser and an evaporator of a refrigerant. Or it is comprised so that heating operation may be performed.

In the outdoor unit, an outdoor fan for generating an air flow is disposed. The outdoor fan introduces external air, and heat exchanges between the refrigerant and air passing through the interior of the outdoor heat exchanger.

Similarly, an indoor fan is arranged inside the indoor unit casing to generate an air flow. The indoor fan sucks the indoor air, and heat exchanges between the refrigerant and the air passing through the interior of the indoor heat exchanger.

In general, in the heating operation of an air conditioner, since only room temperature rises without supply of water, the relative humidity in a room may fall drastically. For this reason, it is proposed to provide a humidification unit to an air conditioner and to supply humidification air to a room. The humidification unit constitutes a disk-shaped humidification rotor with porous moisture absorption materials, such as zeolite, which adsorb | sucks moisture in air and heats the adsorbed moisture, for example, and supports it rotatably. A moisture absorption fan for introducing air to adsorb moisture in the humidification rotor and generating an air flow passing through a part of the humidification rotor, and an air flow for conveying humidified air containing moisture released from the humidification rotor to the indoor unit side. It is equipped with a humidification fan to produce it. The air flow by the moisture absorption fan and the air flow by the humidification fan are respectively configured to pass through the humidification rotor at a position different from the rotation direction of the humidification rotor, and the humidification rotor is heated at a position where the air flow by the humidification fan passes. The heater is arranged.

Water contained in the air flow by the moisture absorption fan is adsorbed to the moisture absorption material of the humidifying rotor. The humidification rotor is rotationally driven by a motor, and the adsorbed moisture is released from the heating position by the heater, and moisture can be supplied to the air flow by the humidification fan.

In the air conditioner equipped with the humidification unit as described above, a large number of parts constituting the humidification unit have been added, leading to an increase in the cost of the entire apparatus. Moreover, in such a humidification unit, the heater for releasing the moisture adsorb | sucked to the humidification rotor is provided. Since the value of the energy consumption efficiency COP of such a heater is almost " 1 ", the energy consumption is large, and the commodity electric power at the time of humidification operation is larger than that of the normal air conditioning display.

In addition, since the air-conditioning unit for blowing humidified air into the room has a uniformly provided outlet of the humidified air so as to increase the humidity of the entire room, it is necessary to humidify the space unnecessarily even to a space where no human is present. In addition, since the humidification effect to be felt is reduced and humidification is performed to a place where condensation such as a wall surface or a window is easy to be condensed, there is a possibility that it may cause excessive condensation and mold generation.

An object of the present invention is to provide an air conditioner capable of reducing humidification operation by further reducing additional components.

In this case, the pressure adjusting mechanism is controlled so that the first heat bridge of the indoor heat exchanger functions as an evaporator and the second heat bridge functions as a condenser so that the number of dew condensation adhered to the outer surface of the first heat bridge is When guided near the outer surface, moisture is evaporated by the heating air heat-exchanged in the second heat bridge and the refrigerant inside the second heat bridge, and the heating air is humidified. Therefore, it is possible to humidify the regulated air after the heat exchange at the second heat bridge portion, and it is possible to supply the humidified regulated air to the room. In a typical air conditioner, the indoor heat exchanger is an essential component, and a part of the indoor heat exchanger functions as an evaporator for dehumidification and the other part for heating so that the temperature of the air blown into the room during the dehumidification operation is not too low. In an air conditioner equipped with an operation mode called reheat dry to function as a condenser, by setting the operation mode in which the reheat dry mode is reversed, it is possible to operate humidification without adding new parts.
