Engineering Air Quality for the Built Environment


Air curtains are one of the HEVAC industries best kept secrets!!



Too few people appreciate the energy saving capabilities of a correctly specified, air curtain installation. The air barrier works to keep opposing environments apart but must be effectively installed and maintained to achieve maximum benefits.

What is the Renewable Heat Incentive going to do for the HVAC Industry?



The introduction of the Renewable Heat Incentive (RHI) next April could allow building owners to make significant savings when looking to invest in their own renewable heat generation technology.

Developed by the Department of Energy and Climate Change (DECC) the RHI will offer fixed annual payments, to those installing the technology. The DECC state that this will result in a 12% rate of return and last for 10-23 years depending on the technology. Some of the eligible technologies include biomass boilers, ground and air source heat pumps, solar thermal, bio-diesel and bio-methane.

Fitting an air curtain with a heat pump energy source could be a way of benefitting from the RHI?



A correctly installed air curtain on its own merit is an energy saving device. Many people think that the small over door heaters often found in small retail outlets are air curtain but they are not. An air curtain creates a stream of air that will help reduce the ingress of cold air into a building but more importantly help keep the warm conditioned air inside the building.

COP – Coefficient of Performance

The coefficient of performance is calculated by the ratio of power output divided by the power input. The highly efficient systems offered by a winning partnership between Toshiba and Envirotec would typically have a COP of around 3.5. For every kW of power you put in you would get 3.5kW of power out.

Combining the energy savings achievable with COP’s of 3.5+ installing an air source heat pump air curtain to help protect the internal building environment and the RHI is a “no brainer” if you want to reduce your heating bills.
Envirotec is launching a new range of over 20 new heat pump air curtain products utilising the unique Toshiba Twin Rotary Compressor Technology of the Toshiba’s Digital Inverter outdoor units
