Wembley
Stadium was the impressive backdrop for the recent LG renewable heating event
that saw the announcement and introduction of the new Therma V R32 Monobloc air
to water heat pump range – the first full range of R32 Monobloc heat pumps
available.
In
addition, LG announced its new partnership with Pacifica Group to provide the
new 0800 Repair service available nationwide for LG equipment operators and
owners and warmed the attendees of the launch to the prospect of the soon to
arrive Metering and Monitoring Service Package – the MMSP – a new tool for
servicing and diagnostic procedures for installers developed with Regin.
LG has
developed a high quality air to water heat pump range over many years under its
Therma V branding. Thousands of these units have been installed up and down the
country. The latest introduction to its popular range, operating on the low GWP
R32 refrigerant available in 5kW to 16kW 1Ø and 12kW to 16kW 3Ø, in a wide
operating range of between 10-135Hz and water temperatures up to 65°C without
an electric backup heater, is the LG Therma V R32 Monobloc range. It comes with
an energy label rating of A+++ (ready for September 2019 erp changes).
The new
version of the Therma V Monobloc contains a plate heat exchanger, expansion
tank and a Grundfos water pump. The new units have a higher capacity due to the
choice of refrigerant. The electric heater can be installed as an optional
accessory as this is not always required.
The
latest units have a 5 to 6dB lower sound power level than previous models and
incorporate a number of additional new features including a new revolutionary
scroll compressor, designed and manufactured by LG Electronics with ‘wet
vapour’ injection. The unit has excellent performance at low ambient
temperatures – 100% at -7°C.
LG units
offer quicker response times for the provision of heating and cooling, by
sensing not only the temperature but also pressure – a pressure control sensor
provides a faster and more accurate response, reducing the time delay for
implementing heating or cooling commands significantly. The addition of
pressure control enables the Therma V R32 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.
Andrew
Hooper is LG’s UK & Ireland Heating Manager in the Air Conditioning and
Energy Solutions business: “As a package for the installer and the end user,
this is a game changer in the air to water air source heat pump marketplace,”
he says.
“The market for air source heat pumps is set to explode in the UK and
this new range puts LG in pole position to take advantage of that increase in
popularity. The UK is currently 25th out of 27 countries
in Europe when it comes to renewable energy which is a sad fact, but one we
need to address. Only 16,000 air source heat pumps were installed in the UK in
the past year – compared to more than 1 million in Germany.
"We
will see the global air source heat pump market swell to around £90 billion by
2020 and here in the UK we will see exponential growth of renewable systems
over the next ten years, whatever happens with Brexit. This new range of LG
Therma V R32 Monobloc units puts us in a very good place, able to provide a
high quality solution to the developers and end users in the UK looking for an
energy efficient, cost efficient, eco-friendly source of heating and hot water
that is ready and able to challenge the stranglehold of the traditional boilers
that we have a love affair with here in the UK.”
The new
offering from LG comes with a revolutionary new scroll compressor combining
high efficiency and low noise characteristics of the scroll compressor with the
stable compressing structure of a rotary compressor in one unit. The new
compressor incorporates new technology developed by LG including wet vapour
injection. This is to control the high discharge temperature of the compressor
efficiently, bringing it down from 160°C to below 110°C, resulting in an
expanded heating operation range and enhancing the unit’s performance at low
ambient temperatures.
The
Therma V R32 monobloc series also incorporates LG’s Ocean Black Fin epoxy resin
coating on its heat exchangers, designed to perform well in corrosive
environments, giving longer lifespan and lower operational costs for the units,
contributing to reliability of the overall system.
LG
equipment has always benefitted from exceptional controllers. The new series
comes with an intuitive controller, with a 4.3” coloured LCD display which is
perfect for installers and end users alike. For example, for the installer, the
controller has various functions for data logging, including operational
history, error reports as well as operation status, amongst many others.
