Citycools portable air conditioners are a less expensive alternative to a permanently installed wall or ceiling mounted air conditioning system. Portable air conditioners can bring comfortable temperatures to your home, office, health care area, retail outlet or any area where a pleasant indoor climate is important.
Citycool offer Irelands widest range of portable air conditioning units, with cooling capacities from 2kw to 30kw of cooling.
Monobloc, ducted comfort coolers:
Monobloc units will have a duct or exhaust hose which is used to expel the hot, humid air from the room being cooled to the outside. They are called mono bloc units because the condenser, compressor and evaporator are housed in a single unit.
The warm humid air is sucked into the air conditioner chilled, dehumidified and filtered and sent back into the room. The warm air, which is created by the air conditioning process, is exhausted to the outside air via the flexible duct. The moisture (condensate), which is also a byproduct of air conditioning, is exhausted, in vapour form, along with the warm air or alternatively collected in a tank within the air conditioner.
Spot coolers:
Spot coolers are also a monobloc type, portable air conditioning unit, however they usually have a higher cooling capacity, are more industrial in appearance and are designed to cool server rooms, electrical equipment, manufacturing or process applications. Cooling only units, these chillers, need to exhaust warm air and collect the condensate in an inbuilt water tank. This tank can be manually emptied or drained away with a condensate pump.
Split type portable air conditioners:
Recognisable by the fact that there are two separate units (indoor and outdoor) linked together via an umbilical chord, which contains refrigeration pipes, cable and drain. These two units are: the condenser (outdoor unit) and the evaporator (indoor unit). The condenser is placed outside and uses a fan to dispel the heat generated by the air conditioning process.
Portable air conditioning units are only designed to heat or cool the room they in which they are located. Although they are equipped with powerful centrifugal fans, distribution of conditioned air is not possible with just one air conditioning unit. However, the cold or hot air can be specifically redistributed to neighbouring rooms by aligning the air flow with a suitable portable fan.
Buildup of heat is cumulative over the course of a hot day. 90% of heat energy that builds up during the day is stored in the building itself. Walls are literally charged woth heat over the course of a day. This stored heat is then released to the room air over the course of the night time. It is best to allow your air conditioning unit “keep ahead” of the heat by leaving it running on auto mode over the course of the day or night.
Air conditioning should not be freezing the room you are occupying. This is just wasted energy consumption. On a hot day, temperatures in rooms should be set between 3°C – 5°C below the outside temperature.
Studies show we are at our best with a room temperature of 20°C. At 28°C our performance drops to 70%. At 33°C we even drop to 50% of our potential. Work place guidelines (ASR A3.5) details that temperature in offices should not exceed 26°C.
Reduce your energy usage, your utility bills and your carbon emissions by following the guidelines listed below:
40% of electricity bills are for heating and cooling. If you can keep the hours of usage to a minimum and reduce temperature settings by even one degree it will decrease your costs.
