2. Heat Pumps / HR Chillers
Heat pumps in hospitals are brodly used for heat and cooling generation. Traditionally, hospitals have heated the facility using hot water or steam boilers which rely on the on-site combustion of natural gas. At the same time, many hospitals are also cooling using a chiller plant and cooling tower to reject heat to the outside and exhausting heat through exhaust fans or economizer systems. A more efficient, and less carbon intense approach would be to satisfy the heating load using a heat pump system. It runs solely on electricity, requires zero on-site combustion. It also recovers waste heat from inside the building to be repurposed for other heating needs such as space or water heating.

3. Alternative HVAC Systems Popular in Hospital Applications. Health Care Facilities Embrace Nontraditional Equipment
Designing an HVAC system for a hospital can be complicated. Not only must the equipment run 24/7, but it must also provide precise temperature and humidity control. It should keep critically ill patients comfortable and sensitive medical equipment operating correctly. Traditional hospital HVAC systems often consist of chillers and boilers. Other types of equipment are becoming more widely accepted in the health care market. They include variable refrigerant flow (VRF) systems, air curtains, and geothermal heat pumps. All are designed to improve comfort and, as an added bonus, save energy.

4. Heated healthcare
Ground source heat pumps (GSHPs) can be installed in most of the UK and provide a clean way of heating buildings by using solar energy stored in the ground. Pipes are laid in a closed loop through a borehole or in shallow trenches and as water is pumped through these pipes it picks up some of the energy stored in the adjacent ground, gaining a few degrees in temperature. The pipes then pass into a heat exchange unit, which works on a principle similar to a domestic refrigerator. It is raising the temperature of an internal circuit that is warm enough to provide space heating and, in some systems, domestic hot water

5. Norrlands University Hospital, Sweden
Transform surplus heat into energy
Thanks to ground storage, which takes heat from bedrock in the winter and provides cooling in the summer the County Council has a reliable supply of low-cost energy. It is now possible to keep spaces that depend on cool indoor temperatures – like operating rooms, blood banks, and laboratory settings – cool. Moreover, surplus heat is used to heat other areas in the hospital as needed. The constant cycle of energy extracted from the ground enables surplus heat to be saved during warm summer months for use in the winter.
Self-sufficient in heating and cooling
The ground storage comprises 125 boreholes, 200 meters deep beneath the large car park at the County Council building. It is one of the world’s 30 largest installations. It is supplying some 5,000 MWh of cooling and 7,000 MWh of heating – enough to heat around 450 houses. These figures translate to NUS having doubled its capacity for producing cooling and heating. The City Council plans to further invest in optimizing cooling and heating installations.

6. Southend Hospital, UK – High Temperature Heat Pump
A heat pump was installed at Southend Hospital in Essex to provide hot water to the hospital training block.
A High Temperature heat pump was selected and installed.

7. Kings Mill Hospital in Nottinghamshire, UK, which provides healthcare for 300,000 people, underwent a major redevelopment.
Part of the renovation was the installation of a geothermal heat pump system specifically deployed to reduce environmental impact and save money.
A 1,400 tons lake-source heat pump cooling and heating system that is capable of producing 5.4 MW of cooling and 5 MW of heating was installed.
A network of heat exchangers submerged in the adjacent Kings Mill Reservoir is connected to 42 heat pumps in the hospital, which regulate the temperature. The system is the largest geothermal lake loop in Europe. It fulfills the hospital’s entire needs for cooling and support the gas heating system when the capacity is available, annually saving 9,600 MWh of gas and electricity.

8. NUS Hospital, Sweden
Heat pumps in hospitals in Scandinavean countries are broadly used. In the north of Sweden, the hospital Norrlands Universitetssjukhus (NUS) has installed heat pump-based heating and cooling systems. The system reduces the energy consumption, the carbon footprint as well as operational costs. Rather than purchasing energy in the form of district heating, district cooling, NUS today is exclusively reliant on electricity to power the heat pumps. As heating and cooling is being produced within the facility, it is increasingly self-sufficient and resourceful.
- Name of building: Norrland Universitetssjukhus (NUS)
- SF:7 Million
- Cost savings: About 500 000 $
- CO2 reduction: 600 tonnes
