Advantages Of Trane Through The Wall Air Conditioners For Hotels

Air conditioning was one of the most important technological developments of the twentieth century

. Trane is a key manufacturer of heating and cooling systems. Following is an overview of Trane through the wall air conditioners.

The two main techniques for cooling air are evaporation and refrigeration. This article does not address the evaporation method. Refrigeration systems actually use evaporation, but the fluid that evaporates is in a sealed system. After it has provided cooling, it is recompressed and reused.

Trane used to be part of American Standard Companies and is currently part of Ingersoll Rand. It makes many heating and air conditioning systems. In addition to air conditioners, Trane also makes gas furnaces, heat pumps, and integrated systems. They have both commercial and home product lines.

Most of the Trane product line consists of large scale cooling systems such as central air conditioning systems. They also make a line of through the wall air conditioners, but they don't call them that. The are Packaged Terminal Air Conditioners (PTAC). They are designed to have part inside and part outside, connected through a hole in a wall. They could be used to cool, and possibly also heat, guest rooms in a motel or hotel. This simplifies separate temperature control for each room. It also makes it easy to turn off the unit when no one is using a room.

Some PTACs are actually heat pumps. A heat pump can either heat or cool. It uses the refrigeration process in either case. When heating it brings heat from outdoors into the area to be heated.

Trane PTACs can cool at anywhere from 7,000 BTUs to 15,000 BTUs, depending on the model. Some have no electrical heating, others have as much as 5 kilowatts. They use either 208 or 265 volt electricity.

There is a remote turnoff feature that is handy in many applications. For example, in a hotel installation, the front desk could turn off units in rooms that are not in use. When a room is about to be occupied, the unit in that room could be turned back on without anyone needing to actually go to the room.

They can work with different kinds of thermostats. Maintenance staff can establish upper and lower limits on thermostat settings. If necessary, a separate temperature sensor can be placed in a better location in the room.

Dehumidifying the air but not cooling it is possible. This is cheaper than cooling and may be just as comforting. Filtered air can be vented in. The filtering reduces dust and pollen in the air, which keeps the room cleaner and makes it more pleasurable to breathe. Trane PTACs are designed to be quiet, and are even quieter with the fan on low.

The unit will automatically switch to electrical heating if the heat pump compressor should fail. After a power failure, each unit will delay its restart by a random amount of time. This helps to reduce the possibility of a power surge. After the compressor is shut down, there is a three minute delay until it will start again. This reduces wear on the compressor by allowing time for the refrigerant pressures to level out.

Large centralized heating and air conditioning systems are becoming the norm in many situations. They do tend to be quiet and efficient. However, there are situations where more decentralized solutions might make sense. In these cases, the Trane through the wall air conditioners are definitely worthy of consideration.
