Space pressure can be either positive or unfavorable with respect to outside the room. Favorable pressure occurs when there is more air being provided than exhausted, and prevails to reduce the seepage of outdoors contaminants. Natural ventilation is a key factor in reducing the spread of air-borne diseases such as tuberculosis, the cold, influenza and meningitis.

Natural ventilation needs little upkeep and is inexpensive. An a/c system, or a standalone air conditioner, supplies cooling and humidity control for all or part of a structure. Air conditioned structures frequently have actually sealed windows, since open windows would work against the system intended to keep consistent indoor air conditions.

The percentage of return air made up of fresh air can typically be manipulated by adjusting the opening of this vent. Common fresh air consumption is about 10%. [] Air conditioning and refrigeration are offered through the removal of heat. Heat can be eliminated through radiation, convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are referred to as refrigerants.

It is vital that the a/c horsepower is sufficient for the location being cooled. Underpowered air conditioning system will cause power wastage and inefficient use. Appropriate horsepower is needed for any air conditioning system set up. The refrigeration cycle uses four important elements to cool. The system refrigerant begins its cycle in a gaseous state.

From there it gets in a heat exchanger (often called a condensing coil or condenser) where it loses energy (heat) to the outdoors, cools, and condenses into its liquid phase. An (also called metering device) regulates the refrigerant liquid to flow at the correct rate. The liquid refrigerant is returned to another heat exchanger where it is permitted to vaporize, hence the heat exchanger is often called an evaporating coil or evaporator.

While doing so, heat is soaked up from indoors and transferred 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 circulation of refrigerant, the heat pump refrigeration cycle is altered from cooling to heating or vice versa.

Free cooling systems can have extremely high efficiencies, and are sometimes integrated with seasonal thermal energy storage so that the cold of winter season can be used for summertime cooling. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes.

The heatpump is added-in because the storage acts as a heat sink when the system is in cooling (as opposed to charging) mode, triggering the temperature to slowly increase during the cooling season. Some systems include an “economizer mode”, which is sometimes called a “free-cooling mode”. When saving money, the control system will open (completely or partially) the outside air damper and close (fully or partly) the return air damper.

When the outdoors air is cooler than the demanded cool air, this will permit the need to be satisfied without using the mechanical supply of cooling (usually chilled water or a direct expansion “DX” unit), thus saving energy. The control system can compare the temperature level of the outdoors air vs.

In both cases, the outdoors air should be less energetic than the return air for the system to go into the economizer mode. Central, “all-air” air-conditioning systems (or bundle systems) with a combined outside condenser/evaporator unit are typically installed in North American houses, offices, and public buildings, but are tough to retrofit (install in a structure that was not created to get it) since of the bulky duct required.

An alternative to packaged systems is the usage of different indoor and outdoor coils in split systems. Split systems are chosen and commonly utilized worldwide except in The United States and Canada. In North America, split systems are most frequently seen in residential applications, but they are gaining popularity in small industrial buildings.

The advantages of ductless a/c systems include easy installation, no ductwork, higher zonal control, versatility of control and peaceful operation. [] In space conditioning, the duct losses can account for 30% of energy intake. The usage of minisplit can lead to energy savings in space conditioning as there are no losses associated with ducting.

Indoor units with directional vents install onto walls, suspended from ceilings, or fit into the ceiling. Other indoor units mount inside the ceiling cavity, so that brief lengths of duct manage air from the indoor system to vents or diffusers around the spaces. Split systems are more effective and the footprint is typically smaller than the plan systems.
