Prepare your cooling solutions now!
Published: 04 February, 2016
“Prepare your panels now and be ready for next summer”. That’s the message from international panel manufacturer and climate solutions specialists, Rittal.
By getting expert advice, and planning and putting in solutions now, managers can get ahead of the game and safeguard their production processes – and not find they are caught out by rising ambient temperatures. “Don’t be lulled into a false sense of security because the temperatures are dropping,” advises Christian Westwood. Rittal’s product manager for Climate offers advice on designing effective climate control systems: “Instead why not use this time to consider your best options?“
Westwood comments that Rittal “always consider options with users from the perspective of functionality, energy efficiency, ease of installation, service and maintenance, based on real life data measured on site.
“I cannot underline how important it is to choose the right product. Climate control is not a one size fits all solution, and its success depends greatly on the local environment.”
Enclosures which are located in a cool and clean environment, may find fan-and-filter units are adequate, given a single device provides more than 4 kW of cooling in ideal conditions.
If the air is dirty, it is still possible to take full advantage of low ambient temperatures by using energy efficient air-to-air heat exchangers to provide any necessary cooling.
For applications that require the temperature inside the enclosure to be lower than that outside it, a refrigerant based solution may be the best option.
The new Blue e+ cooling unit range from Rittal, with capacities up to 6 kW, can operate in ambient temperatures up to 60oC yet also provide free cooling when the external air is cooler due to the innovative use of hybrid technology. Air-to-water heat exchangers may be used in even hotter conditions and the water delivered to a remote location in which the heat, up to 10 kW from one unit, may be dissipated more effectively and with less effect on the temperature of the surroundings.

WEGER AIR SOLUTIONS UK says its ‘RFM’ range of ventilation heat recovery units with integral heat pumps offers designers a unique solution to an age old problem. There are six sizes in the range with air flow rates of 0.25 mᶟ/s to 1.11 mᶟ/s . Each unit consists of supply and exhaust air fans, a plate recuperator for air to air heat recovery and a heat pump refrigeration system, using a scroll hermetic compressor (R410A) with evaporator and condenser coils.
WEGER AIR SOLUTIONS UK reports it has expanded its product range with the introduction of 5 models of heat pump to air heat recovery units. All of the units are ‘stand alone’ and only need electrical power, so are said to be ideal for applications where hot water, chilled water and gas are not available.
