DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ventilating/heating/cooling device installed in an attic space that cools a room and ventilates the room and the attic space.

2. Description of the Related Art An example of a room in which a conventional ventilation system and air conditioning system are installed will be explained with reference to FIG. In the figure, the air conditioning system is a separate heat pump near conditioner consisting of an indoor unit 1 and an outdoor unit 2, and uses a refrigeration system consisting of a compressor, condenser, evaporator, capillary tube, etc. (not shown). This is what I did. An example is shown in which a ceiling-embedded ventilation fan is used for indoor ventilation, which is composed of a ceiling-embedded ventilation fan 3, a suction port 4 provided on the ceiling surface, a suction duct 5, and an exhaust duct 6. Ventilation in the attic 7 is carried out by natural convection by providing two or more vents 20 on the wall in the attic that is in contact with outside air. In addition, ventilation in the room was normally done through window 8.

Problems to be Solved by the Invention In such a conventional configuration, it is impossible to easily remove and move the indoor unit 1 of the near conditioner attached to the wall, so it is necessary to rearrange the furniture etc. in the room. Indoor unit 1 often gave a sense of discomfort to the room. In addition, the ventilation in the attic 7 uses natural convection, so the ventilation efficiency is poor, and when cooling, the air in the attic 7 is warmed by radiant heat from the roof, leading to an increase in the air conditioning load. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and aims to provide a ventilation/heating/cooling system that does not occupy indoor space during installation and allows easy switching and adjustment of air conditioning conditions.

Means for Solving the Problem In order to solve this problem, the in-ceiling type ventilation and heating/cooling system of the present invention has an indoor air inlet and an indoor air outlet provided on the ceiling surface, and a ceiling installed in the ceiling. back air intake port,
A duct that was equipped with an outside air intake port and an exhaust port and communicated with these ports on each day was arranged in the ceiling so that the other end of the duct communicated centrally to one location. Further, at least one blower is provided in the concentratedly connected portion so as to blow the air sucked in from the suction port to the blowout port or the exhaust port, and a damper is provided in each of the ducts to adjust the air volume. At the same time, a heat exchanger for heating and cooling was provided in the duct connecting the g1 feeder and the palm air outlet.

Operation With the above configuration, the damper in the duct communicating with the outside air intake port and the damper in the duct communicating with the indoor air outlet can be opened, or the damper in the duct communicating with the indoor air intake port and the damper in the duct communicating with the indoor air outlet can be opened. Indoor ventilation can be achieved by using a damper in the duct and operating a blower.

Further, ventilation in the attic can be performed by opening a damper in a duct communicating with the attic air inlet and a damper in a duct communicating with the exhaust outlet.

When heating and cooling a room, open the damper in the duct that communicates with the indoor air inlet and indoor air outlet, operate the air conditioner and blower, and when the air passes through the air conditioning heat exchanger, cold air or air will be released from the indoor air outlet. Warm air blows out. Further, at this time, by opening the damper in the duct communicating with the outside air intake port or opening the damper in the duct communicating with the exhaust port, the room can be ventilated at the same time. Furthermore, by appropriately adjusting the opening degree of each damper in the duct, various types of ventilation or a combination of ventilation and heating and cooling can be performed, and ff1l can also be adjusted.
