Abstract

PURPOSE:To prevent a decrease in the performance during heating operation and to reduce the power consumption by integrating all the air conditioning equipment such as an outdoor unit, chilling unit, a pump, a hot water boiler, etc. into a casing. CONSTITUTION:A casing 1 is divided into a machine compartment A and a boiler compartment B by a partition 2 so as to form an air path (C). A heat exchanger 5, a compressor, a refrigerating unit 6 including a water heat exchanger, etc., a cold-hot water pump 7, a blower 8, a motor 9, an electric instrument box, etc. are arranged in the air path C, and a hot water boiler 11 is installed in the boiler compartment B facing the heat exchanger 5. During heating operation, dampers (a) and (c) are closed and a damper (b) is opened. Outdoor air from an outdoor air inlet 4 and warm room air from an exhaust air inlet 3 passes through the boiler compartment B, where air is pre-heated by the boiler 11, and flows into the machine compartment A where heat- exchange and heat-recovery take place in the heat exchanger 5. Thereby, frosting on the heat exchanger is completely prevented, solving the anxiety about a decrease in the heating performance, etc.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention aims to prevent a decrease in performance in cells that have been conventionally arranged differently, and also to significantly reduce power consumption. , energy-saving, low-noise type pneumatic Japanese clothing;

[Conventional technology]

Al1 learning "Eni°" is the formula S, - Heat is exchanged with cold/hot water at the appropriate temperature using a water conditioning machine, etc., and this is passed through a water pump to a fan coil unit installed indoors, and the air handler is used for its performance. They have the function of sucking in air from the periphery and blowing it out from the top, and because they are accompanied by noise and noise, they are generally installed outdoors in most cases.

[Problem to be solved by the invention]

Installing the original air conditioning equipment outdoors as described above poses various social problems such as the relationship between the surrounding environment, the installation space, the degree of corrosion caused by wind and rain, danger, and the generation of noise. However, during winter heating, heating capacity in cold regions is significantly reduced due to weather conditions.

It was also said that frost builds up on the heat exchanger even at low temperatures, making the structure complicated and expensive due to the provision of an electric heater or a defrost circuit as a means to remove this.

Furthermore, if the indoor exhaust is determined based on the Building Control Law, a hot water boiler is used in conjunction with the heat pump chiller unit to raise the hot water of 40°C to 50°C to a temperature of 60°C to 70°C, and then each unit equipment in the room is heated to a temperature of 60°C to 70°C. Because the boiler is installed separately, it not only takes up installation space, but also the amount of heat generated by the boiler and most of the indoor exhaust heat is released naturally, making it extremely uneconomical.

[Means to solve the problem]

In view of these shortcomings, the present invention attempts to effectively utilize the amount of naturally released heat, and its general configuration is to install external air and indoor exhaust intakes at the top or side of the front of the aircraft. An opening is provided and a ventilation passage is formed inside, and mechanisms such as a heat exchanger, a refrigeration machine, and a blower are arranged in the ventilation passage, and a hot water boiler is adjacent to the front part of the heat exchanger. It is an object of the present invention to provide an air conditioner 1i characterized in that it is arranged as follows.

[For production]

Each damper in the fuselage n1 ventilation passage is switched during cooling and heating, and the cold and warm air from the outside air-indoor exhaust intake is switched and sent only to the machine room or to the boiler room, but this is especially true during heating. By sending the residual heat absorption air in the boiler room to the machine room side, this air is applied to the heat exchanger, which not only saves energy but also produces an effective heat loss effect.

To explain in detail, the inside of the fuselage (1) is divided into a machine room A and a boiler room B by a partition plate (2), and an indoor exhaust air intake is installed at an appropriate location such as the upper or front part of the room A%B. (3), an outside air intake (4) and an exhaust port (b) on the rear side of the fuselage (1), and a ventilation passage that communicates the respective openings (3), (4), and (2). C is formed inside the fuselage (1). Inside the ventilation passage C are a heat exchanger (5), a compressor, a water heat exchanger, etc. Refrigerating &! ! (6)
, cold/hot water pump (7), blower (8), electric motor (9)
, electrical equipment box αQ, and other mechanisms, and a hot water boiler (
b) will be installed.

It is also a part of the idea that a large number of fins d are attached to a part of the vibrator aυ on the exhaust port side of the hot water boiler (b) described above to further enhance the thermal effect of the boiler.

Note that in the drawings, duct piping connected to each mouth portion is omitted.

The present invention is an air conditioner 1 according to the above, in which a damper (a) is installed in a part of the ventilation passage C near the room self-exhaust air intake (3) and the outside air intake (4), for example, the partition plate (2). ), (C
) are provided so that they can be opened and closed, and the air flow in the machine room A and boiler room B is configured to be cut off or switched to communicate depending on the cold or warm season.

Shi'jff? '<During cooling, by closing the damper (ω) and opening the damper (b), low-temperature air inside the room does not flow into the boiler room B, and the cooling temperature is
(6) and other mechanisms are arranged in sequence, and a hot water boiler aυ is installed on the front side adjacent to the machine room A heat exchanger (5).
is attached.

In addition, one entrance part of the U-shaped ventilation passage C mentioned above is connected to the fuselage (1
), the indoor exhaust inlet (3) and the outside air inlet (4) open at the top of Each of the dampers (ai, (b5, (Cf), (Cf, 1) provided in the niche can switch the ventilation passage in the same way as above.

Indoor warm air 11 passes through the boiler B room from the indoor exhaust intake port (3) and is transferred to the island. This shows an embodiment in which the ventilation passage C in the machine room A, which is the main body, is formed into a U-shaped ventilation passage by a partition plate (21), and a heat exchanger is installed in the U-shaped ventilation passage in the same manner as above. (5), Furthermore, in the present invention, bypass piping Ql k is connected between the hot water boiler αη and the heat exchanger (5).
i+''), it is also possible to use the high temperature water from the hot water boiler θυ during winter to prevent frost formation on the heat exchanger (5) and to greatly reduce the heat source.

Further, the blower (8) in the blower passage C is not only used for circulating outside air, but also serves as an exhaust blower by being connected to the room through a duct, which not only saves energy but also makes the room very quiet.

The air conditioner y according to the present invention has the above configuration, and during cooling, the dampers (a) and (C
) as a closed circuit, the low-temperature air from the indoor exhaust and the outside air flow directly into the machine room A.
, (a), and (C), the indoor warm air flows into the boiler room B along with the heat source air, and this mixes with the warm air in the boiler room B and the residual heat of the hot water boiler Qυ, resulting in considerably high-temperature hot air. On the other hand, the ventilation passage C in the machine room A can be ventilated.

Although the above explanation refers to a cold/hot water type mechanism, it is of course possible to use other gas type systems as well, such as a combination of a ten-pump type packaged air conditioner and a hot water boiler,
It goes without saying that any configuration can be made, such as a combination of a heat pump type chilling unit and a heating boiler or hot water boiler for hot water supply.

Since the present invention has the above configuration, it also has the remarkable effects described below.

Since all the air conditioning mechanisms such as resolve all concerns.

Further, the above-mentioned hot water boiler may be any type of boiler, such as a hot water boiler, a heating boiler, or a dual-purpose boiler.

Furthermore, by forming the ventilation passage according to claim 0 into a substantially U-shaped passage, the entire ventilation distance becomes longer, unlike a simple straight passage, and therefore various mechanisms can be arranged effectively and the overall shape can be reduced. It can be made extremely compact, and the noise generated inside the machine is naturally absorbed during passage, resulting in very low noise.

Further, the hot water boiler and the heat exchanger according to claim 0 are connected by bypass piping, and a part of the hot water of the hot water boiler is circulated to the heat exchanger side, thereby preventing frost formation on the heat exchanger. Of course, it is not necessary to provide an electric heater defrost circuit for preventing frost, and it is very economical, and the efficiency of the heat exchanger can be significantly increased.

However, by making the blower in the ventilation passage according to claim 0 also serve as an exhaust blower, there is no need to install a separate blower for outside air circulation, and the overall effect is the same as above. It has the advantage of being compact and extremely economical.
