This paper describes a parametric study of residential ground source heat pump
system design for a house in Stockholm, Sweden.
The team responsible for the world's largest zero carbon 90C (194[degrees] F) ammonia district heat pump
, which has been installed in Scandinavia but designed and manufactured in Glasgow by Star Refrigeration, received the prestigious Rittinger Award at the International Heat Pump
Conference in Montreal recently.
Global heat pump
market is driven by growing demand of technology using renewable energy resources and emitting less CO2.
"Used on their own, geothermal heat pumps
are capable of producing large reductions in energy use and peak demand in buildings," Lawrence says.
Underfloor Warehouse currently sells 80 to 100 heat pumps
every month - a fantastic figure which is continuing to grow."
Until recently, heat pumps
have not been especially energy-efficient because that was not a critical factor in their design.
"After the economy went haywire, we experienced a downturn in our current market with the types of installations we had been doing in our area, so I started studying about ground source heat pump
(GSHP) systems," Schmitt says.
I fail to see what the age and "inefficiency" of the housing has to do with the viability of a heat pump
. The installation of a ground-source heat pump
is intended to reduce the energy used for heating a given house.
The White Paper provides for a geothermal contribution of 5 000 MWth for 2010, equally divided between low energy applications and geothermal heat pumps
. Our forecasts (8 480 MWth) go beyond this estimate and the figures are distributed differently: 83% for geothermal heat pumps
and 17% for low energy applications.
The ministry estimates that using geothermal heat pumps
for air conditioning, for example, would result in an energy saving of nearly 40%.
Maribor University's Laboratory for Thermal Energy developed software to model the structure of heat pumps
and the influence of different temperatures; and conducted simulations to assess the impact of different types of coolant on the pump's running costs and efficiency.
When specified as components in a closed-water-loop heat pump
system, McQuay water-source heat pumps
deliver efficient energy transfer while meeting a facility's part-load and seasonal load requirements.
