Office air conditioning hire products |
Call us on 0800 1694768 |
| A wide range of monobloc and split air conditioners suitable for office use are stocked in our warehouse in Vauxhall. Monobloc units exhaust the heat from the room by a tumble dryer type of hot air exhaust hose which discharges the heat outside whereas split units have a small condenser unit which is placed outside to discharge heat. Each product from a range of manufacturers has strengths and weaknesses in each application. We will always ask about your proposed use and advise on the unit most appropriate for you. Factors to be taken into account are cooling output, application, condensate disposal system, physical size/shape, appearance, exhaust hose length needed, ambient noise levels, type of controls, need for swing louvres and proximity to staff. Some general guidance on the choice of type of air conditioner is given below which includes limitations on the use of certain types. The hire cost of similar output units is the same so once the cooling output needed is established the choice of the best unit for you is not influenced by cost.

Calculating How Much Cooling is Needed |
| To determine the amount in KW of cooling needed in an office environment we need to take a number of factors into account, inlcuding:- |
|
| As a general guide for offices the starting point would be to allow 120 watts of cooling per square metre and then make adjustments for abnormal factors including those listed above. This means that our PM38Q model at 3.8 KW of cooling output would be adquate for an average office of 32 sq mt. However, as made clear below the ability of a monobloc unit to maintain an ambient near to 22 deg C when the incoming ventilation air reaches 30 deg C is limited and a split unit is better. |
Choice Of Air Conditioner Type |
| The choice of which type of air conditioner to use will often depend on the practicalities of the installation. If you have opening windows in the vicinity of the air conditioner then the simplest installation will be a monobloc unit with the exhaust hose to the window. Where it is possible to locate a small condenser outside with the flexible refrigerant hose passing to the indoor (evaporator) unit then this has a number of advantages. A summary of the advantages and disadvantages of each type, monobloc, split or evaporative cooler, follows. |

Evaporative coolers |
| Evaporative coolers are not air conditioners but are a fan which evaporated water from a tank into the air flow to create a cool flow of air which has had moisture added. Their effectiveness is very dependent on the humidity of the ambient air. The dryer the air the more evaporation takes place and the lower is the resulting air temperature from the unit. |
|
Spot Cooling |
| Cooling of the whole area is sometimes just not practical, in areas such as in warehouses and workshops. Spot cooling or creating respite areas may be the way forward. It may also be advisable to create air movement to increase heat transfer from staff and improve their comfort. Where heavy manual tasks are are involved spot cooling can have a significant effect in improving productivity in hot weather. Industrial units with more powerful output fans are most suitable for spot cooling. |
The Value of Good Advice |
| The best outcome will only come from a proper assessment of the cooling load, the right choice of equipment type and the appropriate model installed to be convenient for you to use. We, at Aircon Hire Ltd have many years experience of assessing the options and choosing the most effective and convenient solution. Use our experience. We provide it free of charge and can visit site to fully familiarise ourselves with the application before making a recommendation, if your require. |
Healthy Working Conditions |
| Whilst there is no statutory maximum working temperature here in the UK, studies show that comfortable, healthy working conditions lead to more efficient working practices and a reduction in days lost due to sickness. Government advice on the importance of thermal comfort is quite specific and takes account of the 6 basic factors of air temperature, radiant temperature, air velocity, humidity, clothing and meabolic heat. Go to the HSE website further information.

Portable Air Conditioner Effect on Humidity |
||
| All air conditioners remove moisture from the air as it is passed over the cold condenser coil and this has the effect of reducing humidity. However, it is relative humidity which is important to our comfort and a relative humidity of around 50% is most comfortable for humans. Refer to psychrometry, relative humidity for further information. The good news on the use of portable units is that whilst they will reduce higher humidities they will not normally lower relative humidities below the 50% figure for best comfort. Very little condensate is produced once 50% relative humidity is reached. |
