Abstract

PURPOSE:To improve the external appearance of a whole residence and at the same time the efficiency of air conditioning by a structure wherein a compressor, a condenser and a blower are installed in a series of air passages comprising an attic, a duct and the space under a floor. CONSTITUTION:A vertical duct 4 is provided within a house so as to extend itself vertically in order to communicate outside air to the series of air passages comprising ventilating holes 6 an attic 2 the duct 4 the space under floor 3 vent holes 8. A compressor 9, a condenser 10 and a blower 11, all of which constitute the outdoor unit of a split type air conditioner, are installed in the duct 4, through which a coolant gas pipe 14 is laid to indoor units 13 containing an evaporator and a blower per unit installed within a room 12. Electrical wiring is also housed in the duct 4. Because apparatus originally to be employed as outdoor unit is provided within the house in order to be heat-exchanged with the air under the floor and in the attic, no injury of the exterior of the whole residence is resulted and yet the efficiency of air conditioning is improved and at the same time the effect of ventilating the space under the floor and the attic is also added.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a residential air conditioning system, and in particular to an improvement of an air conditioning system using a striped near conditioner that is separated into two units, an outdoor unit and an indoor unit, and connected via refrigerant gas piping. It is related to.

Sufu' IJ Watt's near conditioner uses a compressor.

The condenser and blower are installed outdoors as an outdoor unit. In this case, it goes without saying that the installation space for the outdoor unit is not required, and the overall appearance of the mansion is not good.

By the way, the lower the ambient temperature of the outdoor unit when the near conditioner is used for cooling, the better.

Also, when using a heat pump for heating, the higher the price, the better. Outdoors does not quite meet this condition.

On the other hand, the temperature under the floor of a house is lower than the temperature outside in summer, and the temperature in the attic is higher than that outside in both summer and winter.

Therefore, it cannot be said to be sufficient from the viewpoint of breathability.

In consideration of the current situation of split-type near conditioners and houses, the present invention does not require a special installation space for an outdoor unit, and allows heat exchange with air that is relatively low temperature in the summer and relatively high temperature in the winter. To provide an air conditioning system for a residence which can ventilate the underfloor and attic of a house while at the same time not impairing the appearance of the house.

That is, 1. The present invention provides a residential air conditioning system using a Sugerit type near conditioner in which a compressor, a condenser, and a blower are used as outdoor units. Each attic is provided with a ventilation hole that communicates with the outside air.

The compressor is installed in a series of air channels consisting of ducts and under the floor.
This residential air conditioning system is characterized in that a condenser and a blower are installed, and piping and wiring between an indoor unit inside the house is housed in the duct.

According to the present invention, one is placed outdoors. The compressor, condenser, and blower are installed indoors.

It improves the overall appearance of the mansion, does not require outdoor installation space, and when using heating in the winter, the high temperature air in the attic can be exchanged with a condenser to improve the efficiency of heat pump heating, and in the summer for.

It is possible to improve the cooling effect by exchanging heat with the relatively low-temperature air under the floor using a condenser, and even in the attic.

It has various advantages such as being able to provide ventilation under the floor. Of course, there is also the advantage that the piping and wiring between the indoor unit and the indoor unit can be accommodated within the duct.

An embodiment of the present invention will be described in detail below with reference to the drawings.

The figure shows a sectional view of the entire house when the invention is implemented on the second floor. Referring to the figure, a vertical duct 4 is provided to extend vertically inside the house so as to communicate between the attic 2 and the underfloor 3 of the house 1. Attic 2 is roof 5
It is communicated with the outdoors through a roof opening 6 installed in the eaves of the building. Further, the underfloor 3 is communicated with the outside air through a vent 8 formed in the foundation 7, as is usual. Therefore, a series of air passages consisting of two ventilation holes 6, an attic 2, a duct 4, an underfloor 3, and a vent 8 communicate with the outside air.

In the duct 4, there is a compressor 9, which is an outdoor unit of a Sgerritt type near conditioner. Condenser 10, blower 11
is installed, and a refrigerant gas pipe 14 to an indoor unit 13 including an evaporator and a blower installed in the room 12 is connected to the duct 4.
It is piped through. Electrical wiring is also accommodated within this duct 4.

Compressor9. The direction of rotation of the blower 11 for the condenser 10 may be switched so that the air flow in the duct 4 is directed downward during heating and toward the ground during cooling.

With this configuration, when air conditioning is used in the summer, relatively low-temperature air under the floor is transferred to the compressor 9. Since the air passes through the condenser 10 to cool the compressor 9 and exchange heat with the condenser 10, the cooling efficiency in summer is improved compared to the conventional case where the air is installed outdoors. Furthermore, the air that has passed through the condenser 10 passes through the attic 2 and is blown out from one ventilation hole 6.

The temperature in attic 2 is heated by solar heat.

During the summer, it is normal for the outdoors to reach high temperatures.

Since the air in the attic is discharged from the two ventilation ports 6 by the air sent from under the floor through the vents 4, the temperature rise in the attic 2 is also suppressed, and therefore, the cooling efficiency is also improved.

Note that the outlet of the duct 4 to the attic 2 should be located as high as possible to allow higher temperature air to escape, and to allow relatively high temperature air in the attic to pass through the condenser 10, increasing the heating efficiency of the heat pump type. can be improved.

In addition, since the temperature under the floor is high both outside and outside in winter, the direction of rotation of the blower 11 is not changed.

Even if you always create a flow of air from under the floor to the attic, efficiency can be further improved compared to the conventional case where the outdoor unit is installed outdoors.

One blower can be operated independently.

Even when cooling and heating are not in use, such as in spring and autumn, the blower 11 can be rotated to ventilate the attic and under the floor, which is preferable from the standpoint of the lifespan of the house. Compressor 9. Condenser 10. The installation location of the blower 11 is not limited to inside the duct 4, but may be under the floor or in the attic.

The blower 11 is used to create air flow to the duct 4.
It is necessary to provide an air passage communicating with the duct 4 and install it therein.

As is clear from the above embodiments, the present invention provides two outdoor units: a compressor and a condenser.

A blower is installed inside the house to exchange heat with the air under the floor and attic, so the outdoor unit can be used simultaneously under the floor and attic.
It also has the effect of allowing ventilation in the attic.
