Abstract

PURPOSE:To provide a uniform room temperature and restrict a loss of thermal energy by a method wherein total heat exchangers are arranged at the suction passage and the blowing passage of an air conditioning auxiliary blower device having the sucking and discharging fan for the suction port and the blowing port in a box so as to perform the heat exchanging operation. CONSTITUTION:When the fan in a box 1 is rotated, a part of indoor air RA sucked from a suction port is divided to flow and flowed downwardly in one of the passages 5 by a fan 4 and at the same time passed through one of the passages 7a of a total heat exchanger 7 and discharged out of the room through the port 9c. Simultaneously, a fresh air having a volume corresponding to the discharged volume of air enters the passage 6 from the port 10a under the suction of the fan 4, passed through the other passage 7b crossing at a right angle with the passage 7a of the total heat exchanger 7 and then blown into the room from the blowing port 3. During this operation, the heat exchanging operation is performed between the blown room air and the introduced surrounding air by the total heat exchanger 7 and thereby a thermal recovery is performed.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is mainly applicable to air conditioning (cooling/heating) in general households and various offices, compared to existing blower-type air-conditioning/heating machines (this is a cooling-only machine, a heating machine). Dedicated machine, dual-purpose Gl k with air conditioning/heating switching type
This device is used in combination with the air conditioner (including the above) to forcefully circulate indoor air.For more details, please refer to the upper and lower sides of the box-shaped hollow box. , and above the box (j) 12-Relating to an auxiliary air blower for air conditioning, which includes a blower outlet for sucking air into the room, and a fan for storing both the ports in the box. .

To explain in more detail, the auxiliary air blower for air conditioning with the above-mentioned configuration was developed by the present inventors through various research and experiments, and a patent application was previously filed. According to the auxiliary air blower, when used in conjunction with an existing air conditioner/heater, all the cold air or warm air sucked and generated by the air conditioner/heater is blown out as usual, while at the same time, during cooling, it is , indoor air that tends to stagnate below the indoor aspiration area, and
)) At 5 o'clock, the cold air was stagnating below the indoor desired air suction area by the air conditioner.
1 suction along a horizontal or almost horizontal surface,
And that? It is possible to mix the cold air or warm air blown from the air conditioner/heater, which not only prevents the cold air or warm air blown from the air conditioner/heater from being overcooled or overheated over time, but also prevents the upper layer of the room from being overcooled or overheated. hot sky,
Or the air throughout the room, including the cold air in the lower layer of the room?
It can be circulated.

■ For both cooling and heating, always set the airflow level from the air conditioner to a level higher than the residential zone.
A circulatory effect as described in item (2) above can be obtained.

This can produce an effect such as that of indoor air from a certain range of height levels, as in the past. Aspirate this? : After being cooled or heated through a heat exchanger, the cooled or warmed air is sent into the above-mentioned suction chamber! In the case of independent operation of a single-circulation path type air conditioner/heater that blows into the room at a specific height level that does not interfere with air, or if it is installed near the ceiling and sucks indoor air? Compared to the case of combined operation of a downward blowing circulator and the above-mentioned blower type air conditioner/heater, (a) the indoor air can be completely rationalized, and the shape of the room to be air conditioned, the location and installation of the existing air conditioner/heater, etc. Depending on various conditions such as the model, it is possible to circulate the flow as a whole rather than in a planned or short-circuit manner, minimizing the difference in temperature between the top and bottom of the room, and averaging the overall temperature in the room. This is especially true for air conditioning and cargo movement when there are many obstacles indoors, such as in an office.

(・) There is no occurrence of localized high humidity areas or low temperature areas, and it is possible to avoid direct impact of supercooled cold air or superheated warm air on the human body, thereby reducing discomfort and adverse effects on health. do not have.

Such a remarkable effect? I have reached the point where I have obtained it.

<Problem to be solved by the invention (technical problem)> However, the present inventors developed the problem first and filed a patent application.
Although the above-mentioned Mizonari product achieves satisfactory results in terms of temperature, which is one of the elements of comfort during cooling and heating, it is difficult to replace indoor air with fresh outside air. Since it does not have ventilation functions at all, it is not possible to provide comfortable and healthy air conditioning in a highly closed room.
Further advances in this aspect are strongly desired.

In view of the above circumstances, the present invention utilizes the circulation of a large amount of indoor air to achieve a sufficient ventilation effect while suppressing energy loss as much as possible, thereby providing an extremely comfortable cooling system. A bunch? The object is to provide an emotional blower for air conditioning with a ventilator that can be realized, and can be made as small as possible and inexpensively as a whole.

<Problem Q'f - Means to Solve (Problem Solving Means)> In order to achieve the above-mentioned objective B, the auxiliary ventilation system for air conditioning with a ventilation system according to the present invention is based on the previously mentioned N1 device (described in detail at the beginning). In this case, a part of the suction indoor air is caused to flow into the box by the fan, and the desired air in the diverted room is released outdoors by the exhaust force of the fan. The outside air corresponding to the decoy? The airflow directions of both are perpendicular or perpendicular to each other and are located in approximately the same plane as the passage introduced into the box by the suction force of the fan. It is characterized by a heat exchanger for indirectly exchanging total heat between the discharge indoor air and the outside air at the intersection of both passages.

According to the device of the present invention having such a characteristic configuration, during the indoor air circulation action shown in the above-mentioned items Ventilation can be performed in a state in which indoor air and a commensurate amount of intake outside air are indirectly exchanged into total F when the indoor air and a commensurate amount of intake outside air pass through the bear exchanger. In other words, while ventilating polluted air and bringing in fresh outside air, the thermal energy loss associated with ventilation is sufficiently recovered to increase heating and cooling operating costs. It can be suppressed as much as possible.

■ In addition, the two air flow paths and heat exchanger for ventilation mentioned above are built into the box, and the air intake was originally built into the box at the seventh point of indoor air circulation. Is it possible to control the discharge and introduction of both airflows for heat exchange by making full use of the exhaustion power and suction power of the exhaust fan, and install one or two fans of equal size for the discharge and introduction of both airflows that need to be exchanged? Due to the omission, υ with a built-in ventilation system.
box? It can be constructed to be as thin as possible.

<Effects of the Invention> Based on the above, when the present invention is used, does the average temperature inside the room and the heat energy loss occur? The synergistic effect of ventilation in a state that is suppressed as much as possible can provide extremely comfortable and healthy air conditioning, and what's more, the entire system? This made it possible to make it as small and inexpensive as possible.

<Example> Embodiments of the present invention will be described in detail below with reference to all the drawings.
