Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air-conditioning/heating machine that is a combination of an air-cooled air conditioner and a forced air supply/exhaust type heater forming a refrigeration cycle.

Conventionally, most air conditioners with a combustor have a combustor built into a separate indoor unit.

In addition, some labor-saving type air conditioners and heaters have a heat pump cycle.

To obtain a labor-saving air conditioner with high performance heating capacity,
In addition to the heat pump cycle, additional work is required such as increasing the capacity of the auxiliary heater in cold regions.

Furthermore, the combustor-equipped air conditioner and the construction-saving type air conditioner and heater each require work to attach a frame to a wall or window.

This invention is intended to eliminate the need to increase the capacity of auxiliary heaters in cold regions, and to allow construction of outdoor areas of air conditioners to be completed with a single wall or window frame. It is something to do.

In order to achieve the above object, this invention arranges the condensing device of an air-cooled air conditioner on the indoor unit side, and connects the wall frame for intake and extraction of condensed air and the air supply and exhaust pipe of the forced air-air heater. It is constructed integrally with a wall frame for taking it outside.

Hereinafter, one embodiment of the present invention shown in FIG. 1 will be explained with reference to the refrigeration cycle shown in FIG. 2.

The cooling equipment includes a compressor 1 installed at the bottom of the main unit, and a condenser 2 installed adjacent to a wall frame 24 fitted into a wall 23.
, a condensing blower 3 for sucking in and sending out condensing air, an expansion valve 4 (see FIG. 2), an evaporator 5 installed at the top of the main body, and an evaporating blower 6.

During cooling, high-temperature, high-pressure refrigerant gas discharged from the compressor 1 enters the condenser 2 and is condensed.

The condensing air 25 is sucked in from the suction part of the wall frame 24, undergoes heat exchange in the condenser 2, becomes warm air, and passes through a passage within the main body.
It is discharged outdoors from the discharge part of the wall frame 24.

The refrigerant condensed by the condenser 2 is adiabatically expanded by the expansion valve 4, enters the evaporator 5, exchanges heat with the suction air 8 drawn from the suction lower of the main body, evaporates, and returns to the compressor 1.

The suction air 8 undergoes heat exchange with the evaporator 5 to become cold air 9, which is blown out from the cold air outlet 10 of the main body by the evaporating blower 6.

At this time, the hot air outlet 12 of the main body is a blind lid.

During heating, the hot air outlet 12 is opened. Heating equipment is
Burner 1 equipped with a combustion blower, ignition device, and oil supply device
7. A combustion chamber 18 in which a burner 17 is installed, a heat exchanger 19 connected to the combustion chamber 18, an air supply hose 16 that supplies air to the burner 17, an exhaust pipe 20 connected to the heat exchanger 19, an air supply port 1
4 and an air supply/exhaust tube 15 having an exhaust port 22.

The wall frame through which the supply/exhaust tube 15 passes is constructed integrally with a wall frame 24 for taking in and taking out condensed air.

That is, the air supply and exhaust pipe 15 is made to protrude from the upper part of the wall frame 24 to the outdoors.

The air supply 13 sucked in from the air supply port 14 is transferred to the air supply hose 16
It passes through the combustion chamber 18 in the burner 17 and is cooled by the suction air 8 in the heat exchanger 19.
The air is then discharged outdoors from an exhaust port 22 as exhaust air 21.

The suction air 8 flows in from the suction lower, undergoes heat exchange with the heat exchanger 19 and the combustion chamber 18, becomes hot air 11, and is blown out from the hot air outlet 12 by the evaporation blower 6.

According to the invention described above, the following effects can be obtained.

(1) No need for work to increase the capacity of auxiliary heaters in cold regions.

(2) There is no risk of a decrease in heating capacity when the outside temperature drops.

(3) Since the wall frame for the air supply/exhaust pipe and the wall frame for condensed air are integrally constructed, the construction can be simplified, the cost can be reduced, and the design can be improved.

(4) Upward blowing of cold air and downward blowing of warm air can be easily performed.
