A JCI Condensing Unit is a part of the natural gas heating unit, which has an integral heat exchanger. There are two main styles of condensing units; those having the condenser in the unit itself and those that come in enclosures or mount. The mounts and enclosures offer more space to the user, for example, the mount style which is installed under the kitchen sink. They are also available for larger areas, like the kitchen, and the bottom-mounted style which may be placed under a fireplace in a fireplace room. They all have the same function but their variations come from how they are designed, in particular, the area of the unit they will cover, the surface that they will touch, and where they are to be installed.
The base of the unit has the water reservoir with the condensing element. This unit is fastened to the water reservoir by either screws or brackets. The unit will have a thermostat which is usually surrounded by the pipes for condensation and which will control the temperature of the steam that is produced. Steam is emitted from the unit’s pipes, where it enters the condensing unit. The water inside the unit travels through the heat exchanger and the water condenses, causing the steam to condense as well.
The steam is pushed out through another pipe which is connected to the home. This pipe will connect directly to the home, without going through the home first. The piping will contain the water supply and it will end with the water valve. Water will continue to flow through the valves until it exits the unit. Steam is expelled out of the unit when the water is switched off, when the water valve opens, when the water is turned on again, or when the valve closes. After the water valve is closed, the unit may be left to cool and then allow the vapor to condense.
