- G’s Fresh – Fresh Air Ventilation System – Covid-19 Response
G’s is one of Europe’s leading fresh produce companies supplying all sectors of the food industry. This ranges from own-label salads and vegetables for supermarket customers across Europe to G’s brand products for the independent wholesale, food service and food manufacturing sectors.
As part of the Covid-19 response and the research that good building ventilation reduces the risk of Covid-19 through airborne transmission, the customer approached JD Cooling to design and install an energy-efficient fresh-air ventilation system to meet guidelines.
“The project was led by the HVAC department of JD Cooling Group, delivered on time and within budget with the feedback from our staff being incredibly positive.”
A ventilation system that supplies fresh air to a number of office and meeting spaces providing a minimum of 10l/s per person.
The project installation included:
- 10No heat recovery ventilation systems.
- The removal of redundant mechanical ventilation equipment in a number of internal spaces.
- 5 No. duct mounted electric heater batteries.
- Installation of grilles, external louvres, and plenums.
- Galvanised steel ductwork.
- Volume control dampers at each grille.
- Insulation of fresh air intake duct, using 25mm foil faced duct-wrap.
Fresh-air ventilation benefits
The system takes fresh ambient air from outside and passes it across a filter and heat exchange unit which is rejecting the room’s stale air. Rather than exhausting the rooms air to outside and losing the energy used to heat it, up to 80% of the energy is recovered to condition the incoming fresh air reducing energy loss.
Each cellular space now receives fresh air, which will help reduces the transmission of airborne viruses, rather than the previous system, which recirculated mixed air.
“The benefit of this will be felt by up to 130 members of staff working throughout the office and some smaller office areas and meeting rooms.
