Klima-Therm has been appointed a distributor for Chinese manufacturer Gree’s photovoltaic-powered VRF air conditioning and split systems.
The announcement follows the company’s recent distribution agreement with Gree for centrifugal chillers, with Klima-Therm becoming the only UK supplier of the manufacturer’s full air conditioning range.
Klima-Therm will stock all popular models of Gree VRF and split air conditioning, plus spares. It is expanding its air conditioning team and recruiting new staff to support the roll-out.
Gree’s direct-drive photovoltaic-powered VRF system is claimed to be the first commercially available system of its kind in the world.
The hybrid solar-electric technology can save end users up to 30 per cent of their cooling energy costs.
The units can be used in heat-pump mode to produce heating or hot water - a typical application being to fill a residential storage tank with hot water during the day ready for consumption in the evening.
Conventional PV-powered VRF systems collect solar energy and produce electrical power, feeding it to a DC-AC converter for use by the VRF.
Gree’s system uses power management system to overcome the need for a DC-AC converter, feeding electricity from the PV array directly to the air conditioning system.
This removes the efficiency losses associated with power conversion, boosting the system’s efficiency and cost-effectiveness.
When conditions allow, surplus electricity not required for air conditioning can be fed back into the grid, giving end users an income from feed-in tariff, further tilting the economics in favour of PV-powered air conditioning.
Roberto Mallozzi, managing director of Klima-Therm, said: “This latest agreement with Gree means that Klima-Therm is now the only supplier in the UK offering the manufacturer’s full range of industry-leading products.
