Listed below are the various types of solar air conditioners currently in the market (Updated 10/2012). 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 certified

All 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 standardhouse ac units for sale type compressors, they get some or all of their powerhow to build a mini ac unitSolar photovoltaic panels produce DC power,should i cover my ac unit in winter 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 because they do not believe that solar contributes to any net energy savings in the system. tested any of these units. One thing we find particularly curious about these claims is the Sedna water heating option. If (and we don't agree) adding extra superheat to the system somehow makes it more efficient, then immediately taking the added superheat back out to make free hot water doesn't seem to fit the storyline. Even if the basic claims are somehow correct, we don't see how you can have it both ways.

Mistbox is built with quality materials and a simple, well-engineered design that will last for years Mistbox monitors its own performance for optimal efficiency, turning itself on and off when conditions are right; the only maintenance required is simply changing the filter annually Water filtration system guards against corrosion and helps keeps the Mistbox manifolds free of clogs, adding up to longer system life, less maintenance, and lower energy costs Community Q & AWe have lived in our home almost a year now and no success on the cooling issues we have been complaining about on our so called "Everything Included " Lennar home @ Layton Lakes in Gilbert AZ.The front bedroom and bath extends out further then the rest of the home so it is much more difficult to keep the temperature as consistant as the rest of the home. Our home is a little over 2100 sq ft and has only 1 ac unit. Othe homes in the area have 2 units.bath and bedroom extending out further then the rest of the home, Lennar should have added another ac unit to help with a more consistant climate control.
