NURSING HOME VILLA FIORITA

Exploitation of geothermal energy for summer and winter air conditioning of the “Villa Fiorita” clinic in Casert

In 2020 the property has decided to restructure the existing heating and cooling system equipped with a condensing heat pumps air and gas thermal groups, with the aim of:

increasing the efficiency of the system and consequently reducing management costs

satisfying the simultaneous and opposite needs of air conditioning and reduce the costs for the production of domestic hot water

simplifying the system and eliminating combustion gas emissions

making the system more silent

The solution adopted is based on multifunction water-to-water geothermal heat pumps WSHN-XEE2 MF 80.2 for indoor installation with cascade operation, automatically piloted by the thermo-cooling energy required by the system. The heat pumps have a 4-pipe configuration to simultaneously meet the needs of hot water, chilled water and domestic hot water.

The use of underground basins as a source of water exchange at a stable temperature has made it possible to increase the performance of the heat pumps compared to the existing system, reducing consumption and operating costs.

Also, having no fans, these units are extremely quiet.

Last but not least, the use of a single fully electric system for heating, air conditioning and domestic hot water production has made it possible to eliminate the natural gas central heating system increasing the ecology of the plant and decreasing the maintenance costs.

The final result is a reduction in consumption of over 60% compared to the previous system.
