Abstract

PURPOSE:To reduce a large amount of energy loss based on sophisticated discrete control in each room and batch system control by installing a discrete control damper to adjust the capacity of inlet air in the midway of an air inlet duct, a main controller to control the main body of a heat exchange air conditioner, and a controller to control a discrete control damper. CONSTITUTION:The outside air flows from an outside air intake duct 15a into a suction port of an air conditioning blower 4 by way of an air intake fan 3a, passing through a total heat exchanger 2. Then, passing through a heat exchanger 5, the air is blown out outdoors by way of air inlet ducts 6a, 6b, and 6c, thus carrying out ventilation. At this time, air capacity control is carried out by dampers 7a, 7b and 7c which are installed in the midway of the air inlet ducts 6a, 6b and 6c allowing controllers 9a, 9b, and 9c with thermistors built-in, to control the degree of opening and closing of the dampers 7a, 7b and 7c in automatic mode so that sophisticated control for each room may be carried out. The control of a main member 1 for heat exchange and air conditioning system is carried out by a main controller 8 with a thermistor built-in as well, thereby performing more sophisticated discrete control based on the two systems as described above.

It is not possible to individually control b and 6c, that is, fine individual control is not possible, and there are problems such as unnecessary room air conditioning and ventilation, resulting in a large amount of energy loss.

The present invention is intended to solve these problems, and aims to reduce the large amount of energy loss caused by detailed individual control in each room and collective control.

Means for Solving the Problem In order to solve this problem, the present invention includes a total heat exchanger, an intake/exhaust blower, an air conditioning blower, a heat exchanger, and a blower in the main body. An air supply duct is provided for supplying conditioned air into each room, and an individual control damper for adjusting the supply air volume is provided in the middle of the air supply duct to control the main body of the heat exchange air conditioner. A main controller and a controller for controlling the individual control dampers are provided.

Function: With this configuration, air conditioned and ventilated from the heat exchange air conditioner body passes through the air supply duct, passes through the damper, and is supplied to each room.
A built-in thermistor controls the room temperature to a set temperature, and a controller that controls the degree of opening and closing of the damper enables detailed individual control in each room and eliminates the huge energy loss of air conditioning unnecessary rooms. will be eliminated.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. Components that are the same as those in FIG. 3 will be described with the same reference numerals. The main body 1 of the heat exchange air conditioner includes an indoor air intake duct 14a that takes in air.

14b, and the refrigerant pipe 1 from the outdoor unit 12 installed outdoors.
3 through a heat exchanger through which the refrigerant fluid passes 2. Air conditioned air supply duct) 6 a, 6 b, 6 c.

It has an air conditioning blower 4 that sends air into the room via a 6d air blower. Dampers 7a, 7b, 7c for individually controlling the amount of air passing through each air supply duct are provided between the air supply ducts 6a, 6b, 6c,
Controllers 9a and 9b have built-in thermistors that control the opening and closing of parts b and 7c.

9C in each chamber, each of the dampers 7a,
7b and 7c, and the outside air is taken in from the outside air intake duct (15a) provided on the side to ventilate the dirty indoor air with fresh outside air, and the total heat exchanger 2
an outside air intake blower 3a that blows air through the air conditioning blower 4, and the indoor air intake ducts) 14a, 14b.
In order to exhaust a portion of the indoor dirty air taken in to the outdoors, the indoor air intake ducts 14a and 14b are also adjacent to the total heat exchanger 2. Exhaust blower 3 for exhausting to the outdoors via an outdoor exhaust duct (not shown) 16b
b, and for controlling the main body 1 of the heat exchange air conditioner,
A main controller 8 connected to the electrical equipment section 8a is provided. FIG. 2 shows air supply ducts 61\-/ 6a, eb, 6c led out from the main body 1 of the air conditioner arranged in each room, dampers 7a,
7b and 7c are shown.

In the above configuration, air conditioning is performed by operating the outdoor unit 12 and flowing refrigerant through the heat exchanger 6, and indoor air intake ducts 14a, 14b are used by the air conditioning blower 4, which has already started operating, to ventilate the room. More air flows in, passes through the air conditioning blower 4, passes through the heat exchanger 6, and enters the air supply ducts) 6a, e.
It is blown into the room via b and 6c. On the other hand, for ventilation, an indoor air intake duct 14a is provided by an exhaust fan 3b.

A part of the indoor air flowing in from 14b passes through the total heat exchanger 2 and is exhausted outdoors from the outdoor exhaust duct 15b. As for intake air, outdoor air flows in from the outside air intake duct 15a by the intake fan 3a, passes through the total heat exchanger 2 through the intake fan 3a, flows into the intake port of the air conditioning blower 4, and is heated by the intake fan 3a. After passing through the exchanger 6, the air supply ducts) 6a, 6b,
The air is blown into the room through 6c for ventilation.

In this way, the air is supplied to each of the seven rooms by the air supply ducts) 6a, 6b, and 6c, but detailed control for each room is carried out by the damper 7a installed between the air supply ducts) 6a, eb, and 6c. , 7b, and 7c control the air volume of each duct and individually control each room.

The dampers 7a, 7b, 7c are controlled by controllers 9a, 9 with built-in thermistors attached to each damper.
Dampers 7a and rb by b and 9c.

Automatically controls the degree of opening and closing of 7C, providing detailed control of each room. The main controller 8 of the heat exchange air conditioning system 1 is controlled by the main controller 8, which also has a built-in thermistor, so that more detailed individual control is achieved.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a total heat exchanger, an intake/exhaust blower, an air conditioning heat exchanger, and an air conditioning blower. By equipping with a damper to control, ventilation and air conditioning are performed at the same time, and the air is constantly conditioned with fresh air.A damper is installed in the middle of the air supply duct, and each has a controller with a built-in thermistor that opens and closes by sensing the room temperature. The main controller controls the main unit of the system as a heat exchange air conditioner, and the two-line control allows for more detailed individual control and allows air conditioning of unnecessary rooms. This has the effect of eliminating a large amount of energy loss and producing an energy saving effect.
