The biggest consumers of electricity are the electric motors used to drive pumps and fans within HVAC systems. If these motors can be made to run more efficiently, energy, CO₂ and financial savings will be made.
As many pump and fan systems run at less than full capacity for much of the time, by installing inverters and high efficiency motors into HVAC systems, it is possible to reduce running costs by up to 60 percent. Furthermore if a 90 kW fan’s speed is reduced by 20 percent the investment in a VSD will have a payback of less than 12 months when in continuous use.
Inverters can significantly cut hospitals energy bills
IDS HVAC experts are on hand to explain the benefits of installing inverters in hospital building’s HVAC systems. Among the benefits include:
- Reduced energy consumption
- Fast payback – typically less than 12 months
- Lower CO₂ emissions – CRC Energy Efficiency Scheme
- Clean air circulation throughout critical areas
- Tighter control over temperature changes
- Enhanced Capital Allowances available
- Lower maintenance costs
- Easy to retrofit into a HVAC system
- Low harmonic solutions available as part of installation design
- Gain control of HVAC costs
- Reduced noise
- Smoother start up, lower electrical and mechanical stresss
With the NHS spending £400 million per year on energy and its CO₂ output having grown by 40 percent since 1990 it is under pressure to find ways to reduce expenditure. A free ‘Energy Efficiency Motor Audit’ from Inverter Drive Systems Ltd will give a conservative estimate on the energy savings that can be made for each site. IDS are already helping UK hospitals save on HVAC energy costs, whilst maintaining clean air supplies for critical areas, as well as saving maintenance costs by reducing mechanical stress on fan and pump applications.
