Air Conditioners In a split system, the compressor condenses and circulates the refrigerant through the outdoor unit, changing it from a gas to a liquid. The liquid is then forced through the indoor evaporator coil or cooling compartment. The indoor unit’s fan circulates the inside air to pass across the evaporator fins.n air conditioner, as part of a central heating and cooling system, draws heat energy out of the house and transfers it to the outside air.

5 Things to Consider When Buying an Evaporative Cooler The key to effectively cooling your home with an evaporative cooler is hot, dry air such as what is found in desert areas like the southwestern United States. In fact, evaporative coolers are most effective during the hottest times of the day and when humidity levels are below 50 percent.owever, depending on the climate where you live, evaporative cooling might not be the most effective cooling option for you. Thus, understanding how evaporative air coolers work will help you decide if this is the right cooling solution for you.

Types of Cooling Systems For evaporative coolers to do their job, they must be the right size. The cooling capacity of an evaporative cooler is measured not in the amount of heat it can remove (Btu), but in the fan pressure required to circulate the cool air throughout the house, in cubic feet per minute (cfm). A good rule is to figure the cubic square footage of your house and divide by 2.

Evaporation Evaporation acts like an air conditioner for the surface because heat is used when water enters the atmosphere as moisture. But at the same time, water vapour acts as a green house gas by trapping radiation in the lower atmosphere. As temperature increases so does the process of evaporation. In addition the moisture holding capacity of the atmosphere increases with temperature. For every 1oC increase in global temperatures there is a 7% increase in the moisture holding capacity of the atmosphere.

Causes and Fix for Frozen Inside Air Handler Coils (Air Conditioning Unit) The system extracts heat from the inside of the house and moves it outside. In this scenario, the air coils inside the interior air handler get very cold, with evaporated freon moving through them. Air passes over these coils and most of the time, you get cool air conditioning in your home.

- Evaporative coolers are most effective in areas of low humidity and hot temperatures. They are not effective in humid climates or during rainy seasons. They are not as controllable as air conditioners, and can use between 3.5 and 10 gallons of water per hour, a consideration for use in areas with limited water supplies. The degree of humidity they deliver is a feature that distinguishes the two basic types of evaporative coolers.

- Evaporative coolers use both electricity and water. How much water is used depends on the humidity of the day and the fan speed that the unit is set to operate on. A portable unit might use up to 4 litres per hour while a central system could use as much as 25 litres per hour. Ducted evaporative coolers must refresh their water supply otherwise it can become too salty, and a range of water management systems are used by different brands/models.

How Your Walk In Freezer Works Fri, 05/18/2012 - 1:28pm. Understanding your walk in freezer will save you money and frustration. Many refrigeration problems are caused by not understanding the operation of commercial refrigeration equipment. The basic cycle of cooling and warming is the same as with a walk in cooler . The walk in freezer in this example comes on at 0 degrees Farenheit and runs until the box pulls down to -5 degrees. Then the condensing unit turns off. The air in walk-in warms from door opening, heat gain through the walls and the product.
