Fuel gas is used for heating in the air conditioning system. The gas is burned in atmospheric burner. Compression systems using the A-frame evaporator in the furnace of the Plenum of the chamber provides cooling. The condensing unit is located outside the building. A single, combined heating and cooling thermostat is often used. In humidistat controls the relative air humidity in air-conditioned comfort. In winter, a humidifier in the Plenum chamber adds moisture in heated premises. In summer the humidity is regulated by condensation of moisture on the evaporator. Stoke removes this moisture.
The warm air from the furnace, forcibly rooms with fan. This is under the filter in the cold air return. At the top of the furnace turns on the fan when the required hood temperature is reached. It also disables the furnace casing, if the temperature rises above a predetermined setting. This is a safety device to keep the furnace from overheating. The electric capacity of the furnace is switched on and off using the control panel.
The panel is located on the outer wall of the furnace.
The agreement is sometimes offered to engage external fresh air as needed. This can be either controlled thermostat or manually. Pilot light, when used, is controlled using a thermocouple. Thermocouples connected in series with electromagnetic valve gas supply line. If the pilot light goes out, the gas burner is turned off.
In the summer located in the center, the thermostat can cause cooling. The same air distribution system is used for heating is used for cooling. However, forced the passage of air through cooled in the evaporator, instead of through a heated chamber. It lowers the temperature of the air. At the same time, he is part of moisture is removed to reduce the humidity. Filter incoming in a duct cleans the air before it reaches a fan...
