Thermoscreens air curtains provide energy efficientsolutions and comfort for retail, commercial,architectural and industrial applications. Acomprehensive range of high-quality heated, ambientand cold store products is available, which can be surfacemounted, recessed or installed vertically.

As a market leading manufacturer, Thermoscreens isactively responding to environmental issues. The needto reduce energy consumption and CO2 emissions isbeing addressed through new innovations andrevolutionary new air curtain solutions.

All products are designed with energy efficiency in mind,and with the introduction of Ecopower Air technology endusers can now benefit from further energy savings andclimate enhancing innovation.

Understanding its responsibility towards sustainability,Thermoscreens adheres strictly to the EnvironmentalManagement Systems BS EN ISO14001:2004.

Underpinning all of this is Thermoscreens’ commitmentto product quality, reliability, performance and delivery– evidenced by accreditation to the Quality ManagementSystems BS EN ISO9001:2008.

Known the world over, Mitsubishi is a trusted globalleader associated with a variety of products and services.Founded in 1921, the company known today as MitsubishiElectric, quickly rose to the forefront of the heating andcooling industry, a position they still enjoy today.

As a leading manufacturer of energy efficient heat pumpsystems, they constantly strive to meet and exceed theincreasing demands placed on the industry. The drive toreduce energy consumption and the impact its use hason the environment is crucial and increasingly importantto us all. Energy efficiency, has long driven MitsubishiElectric to spend millions of pounds and huge amountsof resource on researching and developing the solutionsof the future.

Responsible Manufacturing

Mitsubishi Electric boasts an explicit commitment tosustainable business practices such as energy andresource efficiency, minimising ecological impacts oftheir products and reducing greenhouse gas emissions.They are the only manufacturer in the industryrecognised by Portfolio 21 as one of the top fivecompanies in the world for their sustainableenvironmental policy. All of their factories are also ISO14001 registered, the international standard thatspecifies a process for controlling and improving acompany's environmental performance and with theadvent of the Green Gateway Initiative, they strive toconstantly promote best practice.

ECOPOWER AIR

Ecopower Air technology increases the energyeffectiveness and energy saving of the HP DXE HeatPump air curtain. The new technology offers superiorclimate separation across a doorway by way of enhancedair stream projection and air stream uniformity.

Air velocity projection and air velocity uniformity are twoof the most important attributes to describe the air streamdischarging from an air curtain used to protect anopening.

Good air velocity projection means maintaining a high airvelocity within the air stream at a long distance from thedischarge nozzle of the air curtain. Good air velocityuniformity is having a consistent air velocity all along thewhole length of the air curtain.

If the air velocity projection and air velocity uniformity ofthe air curtain is adequate, see Figure 1, it will reach rightacross and cover an opening, thereby, reducing theingress of air and/or condition the air that may enter theopening.

If the air velocity uniformity is poor some partsof the air stream will protect the opening whilstother parts will not, leaving some areas of theopening unprotected, see Figure 3.

As shown in Figure 2, if the air velocityprojection is inadequate the portion of theopening furthest from the air curtain isunprotected.

1. Air Plenum:is a pressure chamber into which the air first flows. Its presence and shape generates ‘Flow Static Pressure’ whichresults in the air being evenly distributed along the length and width of the air curtain discharge area thus eliminatinglow velocity zones or dead zones.

2. Converging NozzleThe plenum transforms into a ‘Converging Nozzle’, (air shaft) creating the Venturi Effect. By moving the air froma larger to smaller enclosure, this creates higher air velocities which results in increased air stream projection.This increased air projection provides an enhanced air barrier.

3. Active Cellular GrilleThe back pressure created by the cellular grille contributes to airflow uniformity. The cellular grille can be angledto achieve the desired directional airflow trajectory to suit the application, enhancing energy effectiveness. The airis guided through each cell of the active grille providing constant coverage.

The new HP DXE Heat Pump air curtain is equipped with Ecopower Air technology which enhances the air velocityprojection, air velocity uniformity and energy effectiveness. These enhancements are a direct result of the air plenum,converging nozzle and active cellular grille (Patent Pending).

ENERGY SAVING WEATHER COMPENSATION CONTROL

The HP DXE Mr Slim Heat Pump air curtain features the Mitsubishi Electric Weather Compensation Control (HEATINGECO). The controller achieves significant energy saving and carbon savings as the heat pump compressorautomatically adjusts for energy requirement. The weather compensation control can reduce the payback period toless than 2 years.The weather compensation control measures the outside air temperature by using an air sensor on the MitsubishiElectric outdoor unit and automatically adjusts the temperature of the air curtain discharge air. It will select a warmerdischarge air stream if it is cold outside and a cooler discharge air stream if it is not so cold outside, as the dischargeair does not need to be as warm.*If the outdoor temperature is 0°C, the discharge air temperature from the air curtain will be 40°C maximum. If theoutdoor temperature is not cold the air curtain discharge air temperature is reduced. If the outdoor temperature isabove 15°C, the air curtain discharge air is not heated and the compressor is off. This means the heat pump system uses significantly less energy and the annual seasonal COP is higher than anormal heat pump air curtain.Figure 1 shows a typical heating curve set up for weather compensation control, temperature points 1, 2, 3 and 4 areselected during commissioning.
