JPH076682B2 - Distributed heat pump air conditioner with built-in window - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a distributed heat pump air conditioner fixed to a window frame for use.

<< Prior Art >> Heating and cooling by a heat pump was separated into an outdoor unit and an indoor unit, and both were connected by a refrigerant pipe.

In addition to connecting the outdoor unit to the indoor unit, electrical wiring was prepared for the power supply line for power and its inlet.

<< Problems to be solved by the invention >> The refrigerant pipe connecting the outdoor unit and the indoor unit tends to be long, resulting in a large energy loss, and the piping work and electrical work are required. The location had to be secured inside and outside the building.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a simple door-to-door distributed heat pump air conditioner that does not require wiring and piping work and installation space inside and outside a building.

<< Means for Solving the Problem >> In order to achieve the above object, a window surface built-in type distributed heat pump air conditioner of the present invention has a compressor and a heat exchanger integrally arranged, and the arranged upper end portion. And an opening corresponding to a discharge port or an exhaust port at the lower end, respectively, and a ventilation path passing through the discharge port through the heat exchanger is provided internally, and the ventilation path is provided with a blower, and the external dimensions thereof Was configured so that it almost matched the window frame.

<Operation> The compressor and heat exchanger are integrated into the window frame to secure a place to install the outdoor unit, supply air from the discharge port and exhaust indoor air from the exhaust port to the outside, or Further, unlike the conventional case, long wiring and piping work between the indoor unit and the outdoor unit is not required.

<Example> Hereinafter, a preferred example of the present invention will be described in detail with reference to the drawings.

FIG. 1 (a) is a front view of the heat pump air conditioner 1 of the present invention fitted in a window frame 2 for a curtain wall as seen from the inside. The room 3 has a double ceiling divided by a ceiling panel 4, and the ceiling panel 4 and the floor slab 5 on the upper floor.
The space formed between and is used as the air supply chamber 6, the free access floor 8 is installed on the floor slab 7, and the exhaust chamber 9 is formed.

The ceiling panel 4 is provided with the outlets 10 intermittently, and the free access floor 8 is provided with the intakes 11 intermittently.

On the other hand, in the case of cooling, the air conditioner 1 has the discharge port 13 at the upper end and the exhaust port 14 at the lower end as shown in the side view in FIG. , A heat pump unit 16 including a condenser and a compressor vertically in series, a total heat exchange unit 17 using indoor exhaust heat,
An exhaust fan 18 is integrally provided, and the left and right of its outer contour are power ducts 19 that can be attached and fixed to the window frame 2, so that the power supply lines and wiring necessary for the air conditioner 1 can be accommodated.

The discharge port 13 and the exhaust port 14 are located so as to face the air supply chamber 6 and the exhaust chamber 9, respectively, when the air conditioner 1 is installed on the window frame 2.

In the case of a window frame with a waist wall or a hanging wall, in the air conditioner 1 installed in the above-described straight line, the discharge port 13 and the exhaust port 1 are provided in each chamber 6, 9.
Since 4 is not positioned, the window edge of the chamber may be lowered in a rectangular shape toward the discharge port 13 and the exhaust port 14 of the indoor air conditioner. Or conversely, discharge port 13, exhaust port 1
4 may be set up and connected to chambers 6 and 9.

Exhaust port 13 and exhaust port 14 if not a double ceiling or double floor
May be left open in the room 3 as it is.

Since it is the case of cooling, the air in the room 3 passes through the suction port 11 through the exhaust chamber 9, is sucked through the exhaust port 14 of the air conditioner 1, passes through the heat exchange coil of the total heat exchange unit 17, and is discharged to the outside. To be done.

On the other hand, the outside air assists the condensation of the refrigerant when passing through the heat pump unit 16 while being precooled by the total heat exchange unit 17. On the other hand, the outside air comes into contact with the evaporator coil 15 and is sufficiently cooled, and is discharged from the discharge port 13 to the air supply chamber 6.
The air is blown into the room 3, and the blowing pressure of the air blows cold air into the room 3 from the discharge port 14 to cool the room 3.

Therefore, the cold air is always fresh air taken in from the outside, and at the same time, the indoor air is used as heat in the total heat exchange unit 17 and is discharged to the outside.

<< Effects >> As described in detail above, according to the window surface-embedded distributed heat pump air conditioner of the present invention, the heat exchangers such as the compressor and the condenser and the evaporator are integrated into the window frame. Because of the structure, the piping has the shortest distance to reduce heat loss, and since it can be installed and installed on the existing window frame, it is not necessary to prepare an installation space.

Further, the discharge port for air supply and the exhaust port are separately provided at the separated positions, and the sensible temperature can be taken into consideration.
