New ICS packaged heat pump delivers 65C output temperatures without any supplementary heating being required
(23/02/2010)
ICS Heat Pump Technology is launching their new commercial 80kW packaged heat pump at Ecobuild 2010. It will deliver 65°C output temperatures, even in ambient temperatures as low as -12°C without any supplementary heating being required.
This packaged unit is geared towards retrofit applications where output temperatures of 65°C will allow heat pump based renewable heating systems to be installed with minimal replacement work on the existing installed radiator system.
An ICS HPT Mod-Pack will arrive on site fully packaged and ready to run. This packaged unit not only incorporates the nominal 80kW 65°C rated heat pump system BUT also has the added benefit of built-in heating and sanitary hot water buffer tanks which allow easy & practical integration to the existing system within the building.
In terms of the Mod-Pack units actual performance in low ambient conditions, the ICS HPT Mod-Pack 80 (Air Source) has a nominal COP of 2 operating in an ambient of -5°C (minus 5°C) whilst providing an output temperature of 65°C.
Installation options allow for a 100% heat pump rated system or alternatively a bi-valent system (option to utilise the existing installed boiler with the heat pump unit), this can integrate the heat pumps via the on-board buffer system with the existing heating system. This option allows fossil fuel boilers to work as a package with the heat pump unit to allow for a cost effective installation whilst providing significant cost and carbon reductions over a full year's operation.
"The retrofit market has to be approached on a practical level", noted Gary Broadbent of ICS," the obvious area to explore with regard to achieving a significant carbon reduction is a buildings high carbon fossil fuel heating or hot water boiler. These existing buildings need a realistic and simple to specify solution that does not involve a large amount of remedial work on the radiator distribution system and possibly does not mean tearing out the existing boiler which may be perfectly serviceable, our HPT Mod-Pack unit allows for as much or as little integration as required with the installed system".
This is the reason why ICS Heat Pump Technology has put a great deal of development into bringing their Mod-Pack 65°C system to the market.
Basically ICS are working on the principle that a well designed heat pump installation will operate at as low a system temperature as possible in order to achieve maximum efficiency & performance i.e. utilising a weather compensated system to minimise heat pump running costs.
But it has to be acknowledged that an older building will not operate year round with a 45°C to 50°C system temperature without a significant and costly amount of refurbishment work on its radiator system.
A building such as this will require a higher temperature output over the peak of the winter due to the demands of its heating profile. This should not be seen as a problem but as an opportunity to specify the next generation of heat pumps which allow a heat pump- system to be specified with confidence in its ability to provide an output temperature of 65°C when it is needed i.e. during periods of low ambient temperature.
This high temperature feature allows the Mod-Pack heat pump system to operate with existing radiators, these radiators will usually only suffer a de-rate of approximately 25% when the system flow temperature reduces from 75°C to 65°C.
Therefore a weather compensated heat pump system that will deliver 65°C can provide the specifier with the opportunity to deliver a practical renewable heating solution to retrofit applications that previously may have been challenging projects in terms of carbon reduction.
ICS HPT Mod-Pack units are available in Air Source or Hybrid Air & Ground Source / Geothermal configurations to suit the demands of a particular application.
"Obviously the Air Source Mod-Pack will be the easiest solution", Broadbent commented," a fully packaged 80kW nominal capacity heat pump system can now be positioned & installed within the area of one car parking space complete with on-board buffer tanks and controls, this unit could be specified to replace a conventional fossil fuel boiler of around 150 to 200kW in capacity".
Heat pumps are now able to provide 100% of a buildings retrofit heating requirements with a 65°C output temperature. This is definitely significant news as the new era of the CRC (Carbon reduction commitment) programme fast approaches, putting much greater focus on existing buildings and property.
