AC Innov R32 heat


pump added to range


L


its latest Therma V air- G Electr onics has added


to-water heat pump to its range, operating on the low


operating range of between and 12kW to 16kW 3Ø, in an available in 5kW to 16kW 1Ø GWP R32 refrigerant and


without an electric heater. It temperatures up to 65°C 10-135Hz and water


comes with an energy label rating of A+++.


The new ver sion of the Therma V Monobloc contains


a plate heat exchanger, expansion tank and a Grundfos water pump. The new unit has a higher capacity due to the choice of refrigerant along with a lower GWP


P,, when compared to R410a. The electric heater can be installed as an optional accessory as this is not always required.


The latest unit has a 5 to 6dB lower sound power level than previous models and incorporates a number of additional new features including a new type scroll compressor, designed and manufactured by LG Electronics with ‘wet vapour’ injection. The unit is said to have excellent performance at low ambient temperatures – 100% at -7°C.


LG units are said to offer quick response times for the provision of heating and cooling, by sensing not only the temperature but also pressure – a pressure control sensor provides a fast, accurate response, reducing the time delay for implementing heating or cooling commands significantly. The addition of pressure c ontr ol enables the Therma V Monobloc to take less time to reach the desired temperatures, with up to 30% quicker response in cooling and 44% quicker response in heating, with a high level of accuracy and stability built in. The Monobloc units incorporate a new scroll type compressor with a seasonal efficiency improvement of 7% over the previous rotary compressor. The new scroll type compressor is one that combines the high efficiency, low noise characteristics of the scroll compressor with the stable compressing structure of a rotary compressor, in one unit. Taking the benefits from both the scroll and rotary compressors, LG’s new scroll type compressor has been optimised for various cooling and heat load operations – low load at low speed, and low noise at high speed – ensuring efficiency increases and comfort improves. The new compressor incorporates new technology developed by LG – wet vapour injection. This is to control the high discharge temperature of the compressor efficiently, bringing it down from160°C to below110°C, resulting in an expanded heating operation range and enhancing the unit’s performance at low ambient temperatures.


Monob


The heat exchangers are coated in LG’s Ocean Black Fin epoxy resin coating, designed to perform well in highly corrosive environments such as contaminated or humid conditions. This ensures longer lifespan and lower operational costs for the units, as well as contributing to reliability in a system.

The new 4.3” coloured LCD displa y has a premium appearance. The interface displays simple graphics, icons and text for intuitive control and as a result doesn’t require a manual. Up to 30 events can be set for each system. For the installer, the controller has various functions for data logging, including operational history, error reports as well as oper ation status amongst many other s.
