Description

[Detailed explanation of the invention] The present invention aims to reliably supply each store with the desired heating and cooling at the same time using a single device in a so-called complex building where a wide variety of stores are located together. The present invention relates to heating and cooling supply equipment.

Normally, multi-type heating and cooling equipment is installed in these types of buildings, but the multi-type has a bulky structure due to its performance and requires a considerable amount of electricity. They only had one function, heating only.

Therefore, it is completely impossible to reliably obtain the desired cooling and heating at each store, and there is a serious economic disadvantage that cannot be solved unless each store individually installs its own heating and cooling equipment. Ta.

In view of the above circumstances, this invention provides the desired air conditioning and heating for each store with a single device, for example, ideal air conditioning at all times for a shopping store, air conditioning for an office, and low heating for an interior store. The purpose of this system is to ensure that optimal heating, cooling, and air conditioning is provided at each store for a specified period of time, and a U-shaped ventilation passage is formed with a partition plate inside to form an intake passage and a ventilation passage. A pre-filter, a blower, and other mechanisms are arranged in the air intake passage, and a chilled water coil and a hot/cold water coil are installed in parallel in the air passage, and the air passage of the chilled water coil is connected to a room where only cold air is required. The air supply passages for the chilled water coil and the hot and cold water coil are connected to outlet A, and the air supply passage for the cold and hot water coil is connected to the air outlet B for an indoor room that requires both cold and hot air. To provide an air-conditioning/heating supply device characterized in that an outlet C and an outside air outlet D are connected to each other so that different types of air-conditioning and heating can be simultaneously supplied to each room.

Hereinafter, the structure of a specific example of the present invention will be described in detail with reference to the drawings illustrating the structure. 1 is an outer box with a partition plate 2 on the inside with an intake passage 3 on one side and an air supply passage 4 on the other side, which is U-shaped. It forms a shaped ventilation passage.

An intake port 5 is opened in the upper part of the intake passage 3, and various mechanical devices such as a prefilter 6, a blower 7, a motor 8, a medium performance filter 9, and a noise reduction chamber are arranged inside.

On the other hand, in the air supply passage 4, a cold water coil 10 is integrally disposed on one side and a cold/hot water coil 11 is disposed on the opposite side, and a bypass passage 1 is disposed in the vicinity of the partition plate 2.
form 2.

Reference numeral 13 denotes a blowout compartment, which communicates with several blowout ports A, B, C, and D opened at the top of the outer box 1, and has blowout opening/closing dampers 14, 15, 16, and 17 provided therein, respectively. The air volume from outlets A, B, C, and D can be adjusted individually, and in some cases, the air volume from outlets A, B, and D can be adjusted.
B, C, and D can be arbitrarily selected to close or open.

18... are the dampers 14, 15, 16, 17
An electric motor for operation, 19 a humidifier, 20 and 21 cold water inlets and outlets, 22 and 23 hot water inlets and outlets, and 24 a humidifying water inlet.

Note that, although it is a matter of course that air sending/receiving ducts are connected to the air inlet 5 and each of the air outlets A to D, they are omitted in the drawings.

The present invention has the above-mentioned configuration, in which the air received from the outside through the intake port 5 passes through the intake passage 3 and is simultaneously heated by the cold water coil 10 and cold/hot water coil 11 in the air supply passage 4. This is exchanged and flows into the air outlet compartment 13 as a heating and cooling system. By operating the dampers 14 to 17 in the blowout compartment 13, the cold and warm air is directed to the respective blowout ports A, B,
It is possible to distribute air differently from C and D.

That is, the cold air from the cold water coil 10 is sent from the outlet A to the shopping zone, and the cold and hot air from the chilled water coil 10 and the hot and cold water coil 11 is sent to the office perimeter zone from the outlet B, and the hot and cold water coil 11 is sent to the office perimeter zone from the outlet B.
This makes it possible to simultaneously supply cool air or warm air to each store through the outlet C to the interior zone and different cool and warm air and air volume for each room.

Furthermore, when a higher air volume and more outside air are required, the amount of air passing through the bypass passage 12 can be easily adjusted by operating a damper.

As described above, the heating and cooling supply device according to the present invention installs the cold water coil 10 and the cold/hot water coil 11 in the air supply passage 4, and connects the air supply side of the cold water coil 10 to the outlet A in a room that requires constant cooling. , the cold water coil 1
The middle part of 1 is connected to the indoor outlet B which requires both cold and hot air, and the indoor outlet C and D which requires warm air from the cold/hot water coil 11 and fresh air from outside.
Since the air conditioner is connected to the air conditioner, it is possible to reliably supply the necessary cool and warm air to each store at the same time, each having a different air volume.

In particular, in this invention, a single device has multiple functions as mentioned above, and since the ventilation passage is formed in a U shape, the overall shape is significantly flattened and small, reducing the installation space. This is an air-conditioning and heating supply system for multi-room buildings that is ideal for the energy-saving era, as it not only significantly reduces power consumption.
