Extraordinary technology achieves exceptional performance Vicot principle schematic diagram of solar air conditioning systemVicot solar air conditioning — a Chinese-American joint development. Three years of collaboration and technology transfer have led to remarkable achievements in solar energy, science and technology, yielding conversion efficiencies for heating and cooling of up to 85%, solar concentrations 27 times higher than ordinary flat plate collectors for water heating. This solar energy technology will truly contribute to preserve our planet. The GWP<1, ODP=0. The natural refrigerant employed will keep our skies blue and our air clean to breathe.

1, Facilitates 24-hour solar power driven air conditioning for cooling, heating and domestic hot water with built-in thermal energy storage2, Provides the capability to use exhaust heat, natural gas, and process gas to operate or supplement heating and cooling.3, Uses a novel concentrating trough collector design with an energy, efficiency of over 75%, four times the energy density of conventional solar water heater collectors.4, Uses MR717 as natural refrigerant without damaging the environment.5, Phase change thermal energy storage using 220°C phase transition molten salt material.6, Return on investment of 3.5 years over conventional electric air conditioners.(in 800W/m2 radiation, 3200 insolation hours/year)7, Electricity saving is 417kW.h/m2 per year.(irradiance: 800W/m2, the sun light hour per year: 3,200 hours)8, Annual CO2 emission reduction is 370 kg/m2.(irradiance: 800W/m2, the sun light hour per year: 3,200 hours)

The Vicot solar air conditioning system consists of three components, i.e. the solar collector, the air conditioner, and the thermal energy storage system. The solar trough collector is designed to be capable of reaching up to 300°C. A heat transfer loop transports thermal energy to the absorption air conditioner. The absorption chiller converts the high temperature heat into building cooling and heating via a hydronic chilled water system. Thermal energy storage is provided via the phase change heat storage system and/or an ice storage system allowing continuous chiller and heater operation throughout the night and during cloudy days.Additional cooling and heating can be obtained from the chiller via use of natural or process gas which can be combusted in the generator of the chiller.
