Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation air conditioner for cooling / heating a building or for ventilation and cooling / heating.

2. Description of the Related Art The conventional heating and cooling method is to provide an air conditioner 101 as shown in FIG. 4, and as shown in FIG. 5, send warm air or cold air to each room through an air supply duct 102. The air is returned to the air conditioner 101 through the air duct 103. The air returned to the air conditioner 101 was accelerated by the fan 105 driven by the motor 104, heated or cooled by the hot / cold water coil 106, and then passed through the air supply duct 102 again and sent to each room.

{For example, regarding air-conditioning and heating methods, "Knowledge of Practical Use of Air-Conditioning Equipment," edited by The Society of Air Conditioning and Sanitary Engineering, P.168} Problems to be Solved by the Invention In this method, the polluted air generated indoors cannot be discharged, and it is necessary to provide another ventilation device for ventilation. However, simply ventilating it will increase the heating and cooling load. In addition, the smell and smoke of cigarettes generated in one room diffused into each room, which often caused discomfort. In addition, there is a problem in that the smell of cigarettes and the like sticks to the inside of the air supply duct 102 and the discomfort increases as time passes.

The present invention is to solve the above conventional problems, it is possible to discharge polluted air generated indoors in a timely and arbitrary manner, and further, it is possible to prevent an increase in the heating and cooling load, and smells and smoke generated in one room are distributed to each room. An object of the present invention is to provide a ventilation air conditioner capable of preventing diffusion and preventing odor from clinging to the air supply duct to each room.

Means for Solving the Problems In order to achieve the above object, the ventilation air conditioner of the present invention comprises:
A heating / cooling section having a fan motor of a blower and a hot / cold water coil for heating / cooling inside the apparatus, and a ventilation section having a fan motor for ventilation and a total heat exchanger for exchanging heat between exhaust air and introduced outside air. And a damper for guiding the indoor air to any one of the heating / cooling section and the ventilation section, and when the indoor air is guided to the heating / cooling section by the operation of the damper, it is heated or cooled as it is. If it is guided to the ventilation part, it exchanges heat with the introduced outside air and then discharges it.
It is configured such that the introduced outside air is heated or cooled and then supplied to each chamber.

Function With this configuration, if the indoor air is not contaminated, if the damper is closed, the wind does not flow to the ventilation part, the wind is guided to the heating / cooling part, and the cooling temperature is passed through the fan motor for blowing. After being heated or cooled by a water coil, it is supplied to each room for heating or cooling. If the indoor air is dirty, or if there is cigarette odor or smoke, open the indoor air to the ventilation section by operating the damper to open it, and the ventilation fan of the fan motor for ventilation. It is pressurized by and is discharged to the outside through the total heat exchanger. At the same time, the outside air is taken in by the air supply fan of the ventilation fan motor, exchanges heat with the indoor air by the total heat exchanger, is then guided to the heating / cooling section, passes through the fan motor for blowing, and then the hot / cold water coil. It is heated or cooled in and supplied to each room for heating or cooling and ventilation.

In this way, heating / cooling or ventilation and cooling / heating are performed.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 is a ventilation air conditioner, which has a blower fan 3 driven by a blower motor 2 and a cooling / hot water coil 4 for heating or cooling the wind discharged from the blower fan 3 A portion, an exhaust fan 6 driven by the ventilation motor 5, an air supply fan 7, and air exhausted by the exhaust fan 6 to the outside and an air supply fan 7.
With the built-in ventilation part having a total heat exchanger 8 for exchanging heat with the air supplied from the outside,
It has a built-in damper 9 for switching the air from the room and the cooling / heating portion or the ventilation portion to the ventilation portion at any time. Reference numeral 10 is a drive unit of the damper 9.
Further, 11 is an air supply duct, one end of which is connected to the ventilation air conditioner 1 for sending warm air or cold air to each room, and discharge grills 12a to 12f are attached to the tips on the side of each room. . Reference numeral 13 is an air circulation duct, one end of which is connected to the ventilation air conditioning system 1 and is for guiding the air circulation from each room to the ventilation air conditioning system 1. The suction grilles 14a to 14f are provided at the tip of each room side.
Is attached. Reference numerals 15 and 16 are outdoor hoods for taking outdoor exhaust air and outdoor air supply of the ventilation air conditioner 1.

In the above configuration, when the air in the room is not dirty, the damper 9 is closed by the drive unit 10 as shown in FIG. 1, and the indoor air sucked from the intake grills 14a to 14f of each room is recirculated. After being guided to the ventilation air conditioner 1 by the air duct 13, it is guided to the blower fan 3 driven by the blower motor 2 and accelerated, and is heated or cooled by the cold / hot water coil 4, passes through the air supply duct 11, and is discharged. It is discharged into each room by the grills 12a to 12f to perform heating or cooling.

Further, when the air in the room is dirty or when there is a smell or smoke of cigarettes, as shown in FIG. 2, when the damper 9 is opened by the drive unit 20, the suction grilles 14a to 14a of the respective rooms are opened.
The indoor air sucked by 4f is guided to the ventilation air conditioner 1 by the air circulation duct 13 and then to the exhaust fan 6 driven by the ventilation motor 5 and passed through the total heat exchanger 8. After that, it is discharged outdoors from the outdoor hood 15. At the same time, by the air supply fan 7 driven by the ventilation motor 5, the outside air is guided from the outdoor hood 16 and the total heat exchanger 8
After heat exchange with the indoor air through the
Is guided to a blower fan 3 driven by, is heated or cooled by the cold / hot water coil 4, is discharged to each chamber through the discharge ducts 12a to 12f through the air supply duct 11, and contaminated air is discharged and fresh. Performs heating or cooling with air.

Therefore, if the air in the room is not dirty, there is no heat loss and heating or cooling can be performed efficiently, and if the air in the room is dirty, heat is exchanged with fresh outside air and exhausted. , While minimizing heat loss, and then heating or cooling as above,
Since it is sent to each room, the smell and smoke of cigarettes are not diffused, and no unpleasant odor sticks into the air supply duct to increase discomfort.

EFFECTS OF THE INVENTION As is clear from the above description of the embodiments, according to the present invention, it is possible to reduce the heating and cooling load, and the smell and smoke of cigarettes generated in one room diffuse into each room, which causes discomfort. Can be given. In addition, it also has the effect of preventing adhesion of odor and odor that cling to the inside of the air supply duct over many years.
