Space pressure can be either favorable or negative with respect to outside the space. Favorable pressure happens when there is more air being provided than exhausted, and is common to reduce the infiltration of outdoors impurities. Natural ventilation is a crucial consider decreasing the spread of air-borne diseases such as tuberculosis, the cold, influenza and meningitis.

Natural ventilation needs little maintenance and is low-cost. An air conditioning system, or a standalone air conditioning unit, provides cooling and humidity control for all or part of a structure. Air conditioned buildings often have sealed windows, because open windows would work against the system planned to maintain consistent indoor air conditions.

The percentage of return air comprised of fresh air can normally be manipulated by changing the opening of this vent. Typical fresh air consumption has to do with 10%. [] Cooling and refrigeration are provided through the elimination of heat. Heat can be eliminated through radiation, convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are described as refrigerants.

It is important that the a/c horsepower suffices for the area being cooled. Underpowered cooling system will lead to power wastage and inefficient use. Appropriate horse power is needed for any air conditioning unit installed. The refrigeration cycle uses four vital elements to cool. The system refrigerant begins its cycle in a gaseous state.

From there it gets in a heat exchanger (sometimes called a condensing coil or condenser) where it loses energy (heat) to the outside, cools, and condenses into its liquid phase. An (likewise called metering device) controls the refrigerant liquid to stream at the appropriate rate. The liquid refrigerant is gone back to another heat exchanger where it is allowed to evaporate, hence the heat exchanger is frequently called an evaporating coil or evaporator.

In the process, heat is taken in from inside and moved outdoors, resulting in cooling of the structure. In variable climates, the system might include a reversing valve that changes from heating in winter season to cooling in summertime. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa.

Free cooling systems can have really high efficiencies, and are in some cases combined with seasonal thermal energy storage so that the cold of winter season can be utilized for summer season a/c. Typical storage mediums are deep aquifers or a natural underground rock mass accessed by means of a cluster of small-diameter, heat-exchanger-equipped boreholes.

The heatpump is added-in since the storage acts as a heat sink when the system remains in cooling (instead of charging) mode, triggering the temperature level to gradually increase during the cooling season. Some systems consist of an “economizer mode”, which is often called a “free-cooling mode”. When economizing, the control system will open (completely or partially) the outdoors air damper and close (fully or partially) the return air damper.

When the outdoors air is cooler than the demanded cool air, this will allow the demand to be fulfilled without using the mechanical supply of cooling (usually chilled water or a direct expansion “DX” unit), therefore conserving energy. The control system can compare the temperature of the outdoors air vs.

In both cases, the outside air needs to be less energetic than the return air for the system to get in the economizer mode. Central, “all-air” air-conditioning systems (or package systems) with a combined outside condenser/evaporator unit are typically installed in North American residences, workplaces, and public buildings, but are tough to retrofit (install in a building that was not created to receive it) because of the bulky duct needed.

An option to packaged systems is the use of different indoor and outside coils in split systems. Split systems are preferred and widely used worldwide except in The United States and Canada. In The United States and Canada, split systems are frequently seen in domestic applications, however they are gaining popularity in small commercial structures.

The advantages of ductless air conditioning systems include easy setup, no ductwork, higher zonal control, versatility of control and peaceful operation. [] In area conditioning, the duct losses can represent 30% of energy usage. Using minisplit can result in energy cost savings in space conditioning as there are no losses connected with ducting.

Indoor units with directional vents mount onto walls, suspended from ceilings, or suit the ceiling. Other indoor units mount inside the ceiling cavity, so that brief lengths of duct handle air from the indoor unit to vents or diffusers around the spaces. Split systems are more effective and the footprint is usually smaller than the bundle systems.
