Abstract

PURPOSE:To enable a heat treatment air conditioning operation and an indoor air processing to be facilitated and efficiently carried out and to provide an entire small-sized shape by a method wherein a heat exchanging chamber and an upper and lower blower chamber divided into two sections are formed in a U-shaped air blowing passage and then an air supplying or discharging adjustment chamber having a discharging damper, a surrounding air intake damper and an air feeding damper is disposed at an intermediate part of the upper and lower blower chambers. CONSTITUTION:An air blowing port 2 and an air returning port 3 disposed at an upper part of an air conditioner 1 are communicated with a U-shaped air blowing passage A and at the same time a heat exchanging chamber B, an upper and a lower blower chamber C and D are formed at a right side and a left side of the air passage. Each of a discharging damper (a) and a surrounding air intake damper (b) is opened, an air feeding damper (c) is closed, the upper and lower blowers C and D are operated, and then cooling or heating air heat exchanged with fresh surrounding air is fed into each of the chambers through a duct communicated with the air blowing port 2. Concurrently, contaminated air in the room is passed from a return port 3 into the blower chamber C through the duct and is discharged out of the air conditioner through the air discharging port 16. The air feeding damper (c) is opened in response to a temperature environment in the room, thereby only a part of the indoor air is released out of the air conditioner to heat the cooled or heated air in the room again and at the same time the surrounding air is fed into the room and then the air is fed into the room as the mixed air.

A heat exchange chamber B and a blower chamber CD divided into upper and lower parts are formed on both the left and right sides, and various mechanisms such as filters, cooling coils, heating coils, humidifiers, valves, etc. are placed in the heat exchange chambers as necessary, and the adjacent In the side blower room, a filter, a return air blower, and an electric motor are placed in the upper blower room C, and an air blower and an electric motor are placed in the top blower room, and the upper and lower blower rooms C and D are arranged. This terminal air conditioner is characterized in that an air supply/exhaust adjustment chamber E having an exhaust damper a, an outside air intake damper b, and an air supply damper C is provided in the middle of the air conditioner.

Sakukawa” Normally, exhaust damper 1 is used to supply cool and warm air indoors.
, open the outside air intake bar B, close the air damper C, and operate the upper and lower blowers.M with fresh outside air.
The exchanged cooled and heated air is sent into each room through ducts connected to the air supply ports.

Further, at the same time that cooled and heated air is supplied to the room, contaminated air inside the room is discharged from the air return port through the ventilation Il chamber via the duct to the outside of the machine from the exhaust port.

Also, depending on the temperature environment in the room, when the air damper C is opened, only a portion of the indoor air is released outside the machine, reheating the cool and warm air in the room, and at the same time introducing outside air and sending it into the room as mixed air. do.

As mentioned above, the present invention makes it possible to easily determine the air flow condition in any direction by adjusting the opening and closing of each damper (a, b, cf).In addition, as shown in the second figure, ducts are installed at each of the exhaust port and the outside air intake port. By connecting the total heat exchanger 411F, more effective heat recovery can be achieved.
