A central air conditioning unit is made of two sections: an indoor coil that is installed within the house and a compressor-bearing section that is usually positioned outside the house. Unlike a portable air conditioner, this cooling system is installed permanently. In addition, central air conditioning units are installed by professionals. How does a central air conditioning unit cool air? This cooling system works by ensuring that warm air is pumped outside and replaced with cool air. When installed properly, a central air conditioning unit provides a room with the desired environment without producing disturbing sounds. A network of ducts connects different parts of the house thereby allowing the system to cool many rooms at the same time. At the heart of this air cooling system is a compressor that circulates refrigerant throughout the house. The refrigerant gathers heat and removes it from your house.

The system is also capable of removing excess moisture from your home. In addition to cooling air and ensuring that the relative humidity is maintained within the desired levels, most central air conditioning units have filters. These filters capture airborne particles to ensure that the air fed into your room is free from dust, insects, and other particles. Some units have sophisticated filters that are capable of removing minute airborne particles and disease causing microorganisms. Air filtration process ensures that the air in your room is not only cool but also clean. The compressor produces disturbing sound but it is located outside the house. This means that a central air conditioning unit produces less noise as compared to most portable air cooling systems. Unlike a portable system, a central air cooling system requires a proper installation plan. Sometimes it is difficult to add this unit to an existing building especially if it was not designed to accommodate it.

This means that this unit can only be installed in houses that have a specific design. As such, it is important to consult a professional before purchasing this unit. In addition, after buying this unit, you will need an expert to install it. If you are planning to boost the environment of your home by adding a central cooling system, now you know how it works and its installation requirements. window ac units cleaningIt’s now up to you to decide whether you will install a central air conditioning unit or you will consider other options.air conditioning units for commercial useListed below are the various types of solar air conditioners currently in the market (Updated 10/2012).window air conditioning units with heat

Solar Powered Chillers (Commercial These chiller systems can be powered by evacuated tube solar thermal collectors or solar concentrators. They can also be powered by recovering waste heat energy from various industrial or commercial process. Basically these systems run on hot water or steam that can be produced in a number of ways including using solar energy. 1. Absorption Chiller Air Conditioners - Lithium Bromide Example: Yazaki Can run on hot water 170-200F range, within range of evacuated tube solar. 2. Adsorption Chiller Air Conditioners - Silica - Example: Eco-Max 3. Absorption Chiller Air Conditioners - Ammonia - Example: Robur (Serval) Can run on hot water >240F range, works with a parabolic solar concentrating collector. Our team has installed and configured several evacuated tube solar-powered Yazaki systems, we have a Yazaki certifiedAll of the above systems are min. 10 tons, commercial use only. Solar PV Powered Solar Air Conditioners (Residential

These air conditioners use BLDC (Brushless DC) compressors, or standard type compressors, they get some or all of their powerSolar photovoltaic panels produce DC power, which in some units is used natively and in others must be inverted to AC. 1. 100% DC Solar Air Conditioners - All DC compressor, fans, and controls- Example: DC48 Telco/Solar All DC powered system built around a pure-DC VRF compressor used in off-grid solar, mobile command posts, telecom cooling. 48VDC, no inverter used, very high efficiency. 2. Hybrid AC-DC Solar Air Conditioners - Mixed Solar AC/DC - Example: ACDC12 The only UL/ETL, EnergyStar, and CEC certified solar mini-split in the market, SEER 35 with 2 solar panels, SEER 19 on normal power, accepts DC power directly, no inverter or batteries needed, uses >80% solar. 3. "Solar Ready" AC units - AC Power - Example: Lennox Central AC system connects to AC power inverted from solar panels and connected to AC line current (grid).

Clever marketing approach, uses inverted solar power but this is an AC powered unit. Hybrid Thermal Solar Air Conditioners (Sedna Aire and various Chinese copycats) The manufacturer claims to have patented technology that uses solar heat added into the normal vapor compression refrigeration cycle, with the claim of saving energy as a result. These hybrid thermal solar "absorption" air conditioners are connected to a solar thermal collector, compressor discharge gas is pumped through the solar collector to pick up additional superheat prior to condensing. 1. Solar Hybrid Thermal Absorption Air Conditioner - AC w/ Solar Thermal - Example: Ecoline(Sedna Aire)This so-called solar air conditioner is included here based only upon claims made by the manufacturer. cannot find any data to verify the manufacturers claims and our engineers do not recognize the Sedna Aire or similar "hybrid thermal absorption systems" as a solar air conditioner
