200x40.indd 1 Condair Aermec
Aermec has announced the addition of two new heat pumps using natural refrigerants to its expanding off ering of energy-effi cient and sustainable HVAC solutions.
Alongside the PRM air-cooled reversible modular heat pump, Aermec has also launched the PRG reversible air/water
When Weatherite needed to develop a cooling solution that didn’t rely on man-made refrigerants, it turned to Condair’s adiabatic cooling expertise. The partnership resulted in Weatherite’s AdTec-D direct cooling system, which is now a highly proven free air-cooling unit, used by leading telecoms and data centre clients. Andy Lewis, General Manager for Data Centres at Weatherite, said: “Incorporating Condair’s adiabatic cooling into our AdTec-D unit has saved 80% of power per unit, compared to equivalent refrigerant-based systems. Condair’s fl exibility and engineering helped us massively in adapting and producing products specifi c to the client’s needs. This allowed us to innovate and really deliver what the client was after. Weatherite’s AdTec-D can off er 15-80kW of sensible cooling per unit, typically operates with an energy effi ciency ratio greater than 15, and is an ideal retrofi t solution for DC or telecoms operations looking to take advantage of free-air cooling. It can operate in free-air cooling only mode when the outdoor conditions allow or utilise adiabatic cooling to boost performance when needed. Even on the UK’s hottest ever recorded day, the AdTec-D successfully maintained the required indoor conditions for a leading UK telecoms provider, without any additional compressor-driven cooling.
heat pump. Both units feature the natural refrigerant R290, which off ers an ultra-low Global Warming Potential (GWP).
Designed to meet the
requirements for commercial buildings and industrial applications, the PRM’s cooling capacity is 95.6kW with a heating capacity of 101.7kW. Hot water can be provided up to 75ºC. The modular design of the PRM allows for up to nine units to be coupled together, reducing the overall unit dimensions to a minimum, providing fl exibility to the designer and future expansion/upgrade of the system. Modularity also provides the user with redundancy and reduced system downtime. Designed for industrial or commercial building applications, the PRG reversible air/water heat pump off ers a cooling capacity of 49.9kW to 146.9kW and a heating capacity of 51.7kW to a maximum of 144.3kW. The design of the unit provides the designer with a wide
operating range, from as low as -20ºC outside air temperature in winter, up to 48ºC in summer, with hot water being produced up to 75ºC. Propane units off er an attractive proposition thanks to their ability to provide higher output temperatures. R290 is a natural refrigerant, and often less charge is required; there’s no glide temperature diff erence and wider delta temperatures. Depending on the application, units can be retrofi tted into existing systems.
