As with all air conditioning systems the principle remains the same whereby the heat is removed from one area and replaced with chilled dry air and the hot air is expelled, normally to the outside atmosphere. As you can see from this typical example of a air conditioning system, the ambient air is drawn over the condensor that can best described as a ‘radiator’ as seen on motor vehicles but instead of water running through the system it contains a refrigerant gas. On its journey around the system it has three main stages; the evaporator contains the sub-cooled refrigerant and air blows through its veins to release the chilled dry air into the room, the condenser contains the high temperature gas that once again air is blown through the veins collecting the heat as it passes through and this is then expelled outside. An air conditioner is able to cool a building because it removes heat from the indoor air and transfers it outdoors. A chemical refrigerant in the system absorbs the unwanted heat and pumps it through a system of piping to the outside coil.

The fan, located in the outside unit, blows outside air over the hot coil, transferring heat from the refrigerant to the outdoor air. Most air conditioning systems have five mechanical components: • an evaporator coil • a chemical refrigerant Most central air conditioning units operate by means of a split system. That is, they consist of a ‘hot’ side, or the condensing unit—including the condensing coil, the compressor and the fan—which is situated outside your home, and a ‘cold’ side that is located inside your home. The cold side consists of an expansion valve and a cold coil, and it is usually part of your furnace or some type of air handler. The furnace blows air through an evaporator coil, which cools the air. Then this cool air is routed throughout your home by means of a series of air ducts. A window unit operates on the same principal, the only difference being that both the hot side and the cold side are located within the same housing unit.

The compressor (which is controlled by the thermostat) is the ‘heart’ of the system. The compressor acts as the pump, causing the refrigerant to flow through the system. Its job is to draw in a low-pressure, low-temperature, refrigerant in a gaseous state and by compressing this gas, raise the pressure and temperature of the refrigerant. where are carrier ac units madeThis high-pressure, high-temperature gas then flows to the condenser coil.car shops in tampa fl The condenser coil is a series of piping with a fan that draws outside air across the coil. replace home ac unitAs the refrigerant passes through the condenser coil and the cooler outside air passes across the coil, the air absorbs heat from the refrigerant which causes the refrigerant to condense from a gas to a liquid state.

The high-pressure, high-temperature liquid then reaches the expansion valve. The evaporator coil is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the coil to absorb heat from the air. The cooled air is then delivered to the house through ducting. The refrigerant then flows back to the compressor where the cycle starts over again. The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system’s efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Filters are located somewhere along the return duct’s length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself. Some types of filters are reusable; others must be replaced.

They are available in a variety of types and efficiencies. Clean or replace your air conditioning system’s filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house. If you use a disposable type filter, it’s always wise to keep several spares inside the house.The tried and true, “smart technology” behind the Ductless Cooling & Heating systems of today has evolved over time. The technology allows energy efficient, individual comfort control with minimal impact on your home as we offer both ductless and limited length ducted solutions. The technology behind Ductless Cooling & Heating systems is referred to in many different ways, including mini-split, multi-split, split-ductless, split-zoning, and variable refrigerant flow. Split-zoning technology is the primary method for conditioning spaces in homes and commercial buildings around the world.

Split-zoning systems allow each room (or space), using an individual indoor air-handler, to be controlled independently from other rooms, thus providing individualized comfort control within each room of a home. A Ductless System uses advanced technology to bring you the ultimate in comfort and control while minimizing energy consumption. A Ductless System uses two small refrigerant lines plus power and control wiring to connect an outdoor unit to each individual air handler. This allows for easy installation in new construction and causes minimal disruption if you are renovating or retrofitting your home. Mr. Slim is a split-ductless air-conditioning system. If you are familiar with a central system, you have the basic idea of what a split system is: an outdoor condensing unit and an indoor evaporator unit. The basic difference between the two is that with the central system the evaporator unit is typically found in the attic and has ductwork branched off to the different rooms in your house.

With Mr. Slim the evaporator is actually in the room being air-conditioned. The indoor unit has a quiet fan that blows across a cold aluminum coil while in the air-conditioning mode. The indoor unit is usually a wall-mounted type, and this unit is connected directly to the outdoor unit by copper tubing and control and power wiring. In the outdoor unit a compressor cycles refrigerant to and from the indoor and outdoor units, and the room air is cooled or heated based on the direction the refrigerant flows between the two. Mr. Slim employs the same mechanical components as any basic air-conditioning system whose interactions cause the process of evaporation to occur. Mr. Slim is a split-ductless design, which simply means the indoor unit is separated from the outdoor unit and is connected by a gas and a liquid refrigerant line. The outdoor unit is considered the hot-side during the air-conditioning process. In the heating process the compressor reverses this operation, and the heat energy is evaporated in the outdoor unit.

Then the indoor unit collects this heat energy while a fan blows air over the indoor coil and distributes the warm air into the room. The process of air-conditioning is dictated by simple physics. Through the evaporation process heat is absorbed by the aluminum fan coil in the indoor evaporator unit and is removed from the room by the gaseous refrigerant. The heated refrigerant (pressured by the compressor) flows into the outdoor unit’s aluminum coils. Here a large fan blows across this coil to discharge the heat energy. The liquid refrigerant is cooled by this process and is cycled back to the indoor unit where a fan blows across it and distributes the cool air into the room. Mr. Slim is designed to circulate air within the space using about the same power as a 40-watt light bulb. Plus there are two standard built-in filters that clean the air and trap virus and toxins while also deodorizing. Mr. Slim’s normal operation takes care of moisture very nicely. The indoor unit’s coil draws the moisture out of the air and wrings it out in the form of condensation that is drained outside or to a near-by drain.

Mr. Slim is rated to remove between two to five pints per hour when the return air temperature is at 80 deg.F dry bulb or 67 deg.F, and the indoor relative humidity is around 50%. The outdoor conditions become wetter and can affect the indoor conditions. This will cause Mr. Slim to remove moisture out of the air at a faster rate. Mr. Slim even has a mode of operation called DRY mode. This dehumidification feature provides added moisture control without lowering the temperature of the room. In this mode the fan speed slows slightly so that the air can spend more time on the indoor coil therefore wringing out more moisture.
