Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention integrates an outdoor mechanism such as a heat pump chilling unit, which has been conventionally configured differently, into a narrow space such as a ceiling in a ceiling or a corridor ceiling. The present invention relates to a ceiling-mounted heat pump chilling unit that can be easily installed in a specific location and that supplies cooling and heating to a predetermined room.

[Conventional technology]

Conventionally, most of the means for supplying air-conditioning to the room are air-cooling that is installed outdoors or a heat medium that can appropriately exchange heat with a heat pump chilling unit through a pipe to an air conditioner such as a fan coil unit installed indoors. Although it was delivered, installing a heat source machine such as the above heat pump chilling unit outdoors, not to mention the risk of damage due to wind and rain, risk of falling, etc., complicated piping, It had various drawbacks such as gas and water leakage due to piping.

[Problems to be Solved by the Invention]

The present invention has a structure in which the outdoor heat source unit installed outdoors is combined with an indoor air conditioning unit to fundamentally solve the above-mentioned drawbacks. It can be easily installed in a small space such as an indoor ceiling, a warehouse, a corridor, etc.

[Means for Solving the Problems]

According to the present invention, as a means for solving the above-mentioned problems, the entire machine body is formed into an elongated shape, and the heat exchange section (A), the pump section (B), and the blower section (C) are respectively formed in the machine body, and the heat exchange section is formed. (A) a V-shaped air heat exchanger and a water heat exchanger in the V-shaped wide space, a pump section (B) a compressor, a pump, a blower section (C) an electric motor, A ceiling suspension characterized by arranging various mechanisms such as a blower and integrally connecting the above-mentioned heat exchange section (A), pump section (B), and blower section (C) in a columnar manner. Type heat pump chilling unit.

Further, each of the heat exchange section (A), the pump section (B) and the blower section (C) constituting the machine body is formed so as to be separable from each other, and at the time of installation, the heat exchange section and the pump section (B) side are a refrigerant unit. Needless to say, the fan unit (C) can be used as a fan block to connect the respective units with ducts so that the unit can be installed more effectively and effectively.

[Action]

The present invention is to install the heat pump chilling unit having the above structure in a narrow space such as a ceiling or a corridor in a room, and connects the intake port and the air supply port to the air supply port in the room through a duct, and heats them. In the exchange section (A), air from inside or outside the room is cooled and heated, and the heat exchanged air is supplied to each room through a blower.

〔Example〕

Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. (1) is an airframe formed with an elongated shape as a whole, and has a front narrow angle V-shaped rear wide angle The heat exchanger (A) having the heat exchanger (2) arranged therein, and the blower unit (C) having the blower (6) and the electric motor (7) arranged at the rear thereof. In the middle of the exchanger (2) and the blower (6), the compressor (4), the water heat exchanger (3), the pump (5), the control device, and other various mechanisms are arranged substantially in series including the inside of the V type. It is arranged. Also the aircraft (1)
, An air inlet (14) in the front, an air inlet (15) in the rear, and an inspection port (12) on the lower bottom surface of the blower unit (C),
Inspection door (13) for maintenance at the inspection opening (12)
Is attached so that it can be opened and closed.

Depending on the case, it is also possible to use the transfer body with the intake port (14) on the air supply side and the air supply port (15) on the intake side. Reference numeral (8) is a liquid receiver, (9) is an electrical equipment box, (10) is a terminal box, and (11) is a vibration isolation mechanism.

Depending on the environmental conditions such as the installation location, a chamber box (D) that also serves as a muffler may be connected adjacent to the blower section (C).

FIG. 3 shows another embodiment of the above-mentioned mechanism, which does not need to integrally form the respective parts (A), (B) and (C) in the machine body (1) as described above, but to form the heat exchange part. (A), the pump section (B) is divided into the refrigerant unit (1A), the blower section (C) is divided into the fan block (1B), and each block (1A), (1B) is formed by the duct (16). It is also a consideration to use it by connecting and communicating.

〔The invention's effect〕

The present invention, as described above, includes the heat exchange section (A), the pump section (B),
Since the entire parts of the blower unit (C) are integrally formed to communicate with the elongated body (1), frost formation due to the outdoor installation of the heat pump chilling unit as described in the section of the prior art, Not only can problems such as defects be solved at once, but it is easy to install even in narrow spaces where it was difficult to install in the past, such as indoor ceilings and corridors, especially because the whole shape is an elongated box type. It has advantages such as being possible.

Further, in the heat exchange section (A), a V-shaped heat exchanger (2)
Since the heat exchange surface is significantly large due to the installation, more effective heat exchange efficiency can be obtained, and various mechanisms such as the water heat exchanger (3) can be compactly housed in the space with a large width of the coil. Since it can be done, there is no need for these installation places, it becomes bulky,
Moreover, by simply opening and closing the inspection door (13), various operations such as inspection and repair of the internal mechanism from the lower surface of the machine body (1) can be easily performed.

Further, by forming each of the heat exchange section (A), the pump section (B), and the blower section (C) as separate unit constructions as claimed in claim 1, various operations such as transportation, installation, and replacement are completed. It goes without saying that the operation is simple and easy.
