Air conditioning as we know it today was developed in 1902 by a young man whose name is synonymous with the industry, Willis Carrier. The original intention was actually to develop a dehumidifying system to keep paper dry in the humid summer months at a printing plant in New York. Carrier blew air across a series of chilled pipes and as cool air can’t carry as much water as warm air, the humidity was reduced hence drying the paper stock. The added benefit was cooler air and the world witnessed the birth of modern air conditioning. In short order Houston air conditioning was showing up in theatres and shops, making the summer months more comfortable.
Air conditioners use a very simple process to bring the ambient temperature in a room down. An air conditioner uses the same principle as your refrigerator, a refrigerator of course has a casing to keep the cold air in, and the air conditioner uses the walls of the house to do the same thing.
When a liquid changes into a gas, a process called ‘phase conversion” takes place, heat is absorbed. Air conditioners use this law of physics by making refrigerants evaporate and re-condense time after time within the closed coil system of the unit. The chemical properties of the refrigerant enable them to make the conversion at low temperature. Within the system are fans which blow warm, moist air over the coils, this air in turn is blown through ducting throughout the building.
Houston air conditioning follows these principles and as the warm air that is blown over the coils and the liquid changes to a gas, the overall efficiency is measured by the rate at which the gas returns to a liquid state to start the process again and again. The heat which is generated during the process passes through another set of condenser coils and is then blown outdoors into the atmosphere. It is a never ending cycle of gas to liquid to gas to liquid.
The primary job of an air conditioner is to cool the air in a given area but it does other things as well. The units are fitted with filters that remove dust and particulates from the air which is circulating and they act as a dehumidifier. All air conditioners have drains to let the water which has been extracted from the air, escape.
Window air conditioners are a complete package in a box, they are small and compact and are designed to fit into a window casing or they can be installed in an opening through the wall. The window unit contains all the same components as a split or central unit; compressor, expansion valve, hot coil, cold coil, fans and thermostat.
With modern buildings in the most part being fully sealed, effective Houston air conditioning, heating and ventilation is a must.
