London Cool specialise in the hire and sale of portable air conditioner equipment to industry and commerce. Our mobile air conditioner range includes equipment for  cooling small and large areas. The versatility and reliability of our portable air conditioning equipment, along with the high level of service we provide, are key to our success in our industry. Our staff are fully trained to ensure you receive the correct portable unit(s) at a reasonable cost and for the most appropriate length of rental time or purchase.

Air Conditioning

A portable air conditioner is a self-contained portable system ideal for cooling single rooms or areas. They typically sit on the floor and come with warm air exhaust hose for quick set up. An alternative type of portable air conditioner might come with water line and condenser. Portable air conditioning is designed to extract heat from an area using a refrigeration cycle. A complete system of heating, ventilation, and air conditioning is referred to as HVAC. Its purpose is to provide comfortable conditions during hot days and nights. Air conditioning units pump out thermostatically-controlled cool air that has been chilled through heat extraction.

Cold Air Outlet Tubes

Portable Air Conditioning units which have flexible cold air outlet tubes are normally called spot coolers and are designed to create an umbrella of cool air. The position of that umbrella is determined by the direction of the flexible cold air outlet tube, often referred to as a nozzle. This unit is ideal for cooling individual work stations or, more especially, critical areas such as IT, Data Centres and Server Rooms. As well as cooling the air, the moisture is re-condensed out of the air and collected in an integral water reservoir that is emptied manually. An automatic condensate pump can be fitted as an extra.

Evaporative Coolers

Evaporative coolers provide a cooling effect by natural evaporation, in the process increasing relative humidity. Fans and air movers increase cooling through air circulation. Evaporative air conditioners do not have a compressor or condenser. Instead, liquid water or ice is poured into a tank and air movement releases this as vapour. Because they do not have a refrigeration circuit, they do not need hoses or pipes, allowing them to be truly portable. These units add humidity and are not suitable for computer, IT or server room applications. In moderate humidity locations there are many cost-effective uses for evaporative cooling, in addition to their widespread use in dry climates. For example, industrial plants, commercial kitchens, laundries, dry cleaners, greenhouses, spot cooling (loading docks, warehouses, factories, construction sites, athletic events, workshops, garages, and kennels) and confinement farming (poultry and dairy) all often employ evaporative cooling.

Warm Air Hose Exhausts

Warm air exhaust portable systems, ‘Air-to-Air’, and ‘Monoblock’ are vented to the outside via air ducts (similar to a tumble dryer). The ‘monoblock’ version collects the water in a tank or tray and should stop when full. The Air-to-Air version re-evaporates the water and discharges it through the ducted hose and can hence run longer between tank emptying. The hose (s) must discharge outside the area being cooled, via a partially open window or door, or sometimes into a false ceiling. We can provide an installation service to make holes through walls where possible.

HVAC

HVAC stands for Heating, Ventilation, and Air Conditioning and is sometimes referred to as ‘climate control’. It is particularly important in the design of medium to large industrial and office buildings and in marine environments. The three functions of heating, ventilation, and air-conditioning are closely interrelated. All seek to provide thermal comfort, acceptable indoor air quality, and reasonable installation, operation, and maintenance costs. HVAC systems can provide ventilation, reduce air infiltration, and maintain pressure relationships between spaces. How air is delivered to, and removed from spaces is known as room air distribution.

Portable Air Conditioning

Portable air conditioners come in three forms – split, hose exhaust, and evaporative. The main uses/advantages of Portable Air Conditioning are:

• It is portable, and so the location can be easily changed.
• Temporary – in areas where air conditioning might not normally be needed, but there is a temporary requirement.
• Emergency – portable air conditioning units can be supplied as emergency backup, in case of installed air conditioning failure – especially critical in such areas as IT, Data Centres and Server Rooms.
• If a permanent solution where installed air conditioning is not possible.

Split Portable Air Conditioners

A split system has an indoor unit on wheels connected to an outdoor unit via flexible pipes, similar to a permanently fixed installed unit. Split system room Air Conditioners come as either refrigerant based or water cooled.
