VRF / VRV Comparison Case Study

LOOKING TO INSTALL A VRF SYSTEM

A restaurant and bar needed to install a VRF system to provide heating and air-conditioning throughout their facility. The restaurant also needed to install a boiler for heating domestic hot water for the kitchen and toilet areas.

A COST EFFECTIVE OPTION UTILISING RENEWABLE ENERGY

The contractor examined the option of utilising an Air Source Heat Pump system and determined that the system would be both cost effective and environmentally efficient, but also importantly the Air Source Heat Pump would provide high grade domestic hot water for the kitchen & toilet areas of the facility.

Also the amount of refrigerant gas in the system was also significantly reduced as the heat transfer would now be achieved using low pressure water rather than high pressure refrigerant gas pipework running throughout the restaurant.

The system provides definite benefits when the F Gas regulations are taken into account as the refrigerant gas charge is greatly reduced and also the refrigeration system is fully self contained within the Heat Pump, hence the potential risk of a refrigerant leak is reduced considerably.

RESULT

An Air Source Heat Pump package was installed to provide an extremely cost effective, environmentally efficient and well designed heating & cooling system that can be used throughout the year with the added benefit of also providing high grade simultaneous domestic hot water.

CONCLUSION

A DeLonghi-Climaveneta Air Source Heat Pump provided the user with a very cost effective alternative to a VRF or VRV system but with some really significant benefits

1. A fast installation utilising a low pressure water system.
2. No refrigerant gas in the building (Air Source unit positioned externally)
3. The risk of a refrigerant leak was significantly minimised due to the reduced volume of refrigerant in the building.
4. Less future demands on the building manager resulting from the F Gas Regulations leak testing requirements.
5. A system which removed the need for a boiler being installed as the Heat Pump provides all the hot water for the building.
6. Heating, air-conditioning and simultaneous domestic hot water from the same unit.

This system will provide Air Conditioning or Heating whilst simultaneously delivering water at over 60 deg C.

CONTRACTORS NOW OFFER A DIFFERENT OPTION

Contractors are now able to offer Commercial Heat Pumps with the DHW option and provide turnkey solutions to their clients offering simultaneous hot water whilst providing heating and air-conditioning along with the added benefit of a much reduced risk of refrigerant leakage from the system.
