Frequently Asked Questions

Hiring Air Conditioning

Air conditioning is the process of cooling the ambient air in rooms/buildings and at the same time controlling the relative humidity by adding back the correct amount of moisture. This is to achieve a relative humidity of around 50%, which is generally considered to be most comfortable. When the air is cooled and no control of humidity takes place the correct term is actually ‘comfort cooling’ but this is more commonly referred to as air conditioning. Air conditioning / comfort cooling are normally achieved by use of refrigerant based systems which utilise two heat transfer coils. The coil, which dissipates the heat, is the condenser coil and the coil over which the air is cooled is the evaporator coil. The condenser can be installed outside the building and the evaporator unit is floor, wall or ceiling mounted inside the building.

A different type of cooler is the evaporative cooler – this is not air conditioning.
It is a fan with a moist filter across it. The filter is kept moist by a tank of water, which needs to be topped up regularly. Air passing through the filter evaporates the water from the filter and the latent heat of evaporation is taken from the air, so making it feel cool. The air is, however, moist and if these units are used in confined spaces then the humidity of the room will continue to rise and as it reaches near 100% evaporation will stop and the unit will stop working. These are best used in open, well-ventilated spaces where a cool breeze is needed and the air is continually vented to the outside.

There are different designs of air conditioner; most people in the UK are familiar with the “split system”. These can be seen in many offices and server rooms where the evaporator is either wall mounted or a ceiling cassette.

Where buildings have central air conditioning systems they can be combined with heating systems and the fan coil units in the rooms can then either heat or cool the area as demanded by the control system or building management system. These systems can be very complex in design whereas split systems are relatively simple and ideal for retrofitting in buildings where no air conditioning has been installed from the outset.

Refrigerant based air conditioning systems often have the facility to operate in reverse. In this mode they are termed as a heat pump. Heat pumps take heat from outside and discharge heat via the coils in the indoor unit.

Whether in air conditioning or heat pump mode these types of systems typically have a coefficient of performance (CoP) of about 3. This means that a 3 KW air conditioner uses about 1 KW of power. Conversely a heat pump provides about 3 KW of heat while using about 1 KW of power.

Where the installation of an air conditioning system is not practical, or is not sensible due to short-term occupancy of the building, temporary air conditioners can be used. Air conditioner hire is common and these units can be split types or monobloc units.
Monobloc air conditioners have both evaporator and condenser coils in the same casing and discharge heat outside by exhausting hot air through a flexible duct, which is taken to a window or a vent in the wall. These air conditioning units will remove moisture from the air and so reduce humidity but they have no means of controlling humidity. Split air conditioners have the condenser coil contained in a housing inside the room and the separate evaporator is mounted externally and is connected with the refrigerant hoses.

Units can be supplied by us from as little as £10 per week.

As with most units, the monoblocs we supply have different fan speeds. Even at the higher speed the fan noise, on the units we supply, would still be indiscernible in the sounds of a normal busy office environment. If you are looking for the quietest unit possible then ask us about the PQ38 unit which was developed for us by the manufacturer thus providing a very low noise air conditioner to hire.

To maintain the right temperatures for comfort levels no matter how warm the weather gets, you do need to have the correct number of portable air conditioning units. If too few units are used then the temperatures will still rise on the hottest days and the comfort levels will drop, particularly mid afternoon in south/west facing offices.
No, monobloc units reduce the humidity as the water is removed out of the air passing through the unit. In the older models the water extracted would be collected and once full the unit would turn off. The models that we provide however vaporise any water collected and vent it to the outside through the connected hose.

The amount of electricity consumed by each unit is dependant on the situation in which it is installed. The unit will only operate on demand when the ambient temperature rises above the desired level. The monobloc units typically use about 700 watts when running.

As there is a thermostat built in, this turns off the unit when the required room temperature is reached.

Practicalities, Installation and Service Provided

To ensure the unit works to its full potential and you get the maximum benefit there is a weekly care procedure, which needs to be carried out. We provide the instructions so that the air filters can be cleaned – a simple and quick process

The monobloc units are required to placed next to a window so that the warm air hose can discharge the heat from the room outside through the window or ventilation system
The size ranges from 130mm up to 160 diameters on larger units. Fish tails and other fittings are provided as required to ensure that the most efficient installation is provided.
A normal 13 amp supply from a wall socket is all that is required. Extension leads can always be used to ensure the unit is placed where required.
That would depend on a number of factors, including room size, electronic equipment used within the room etc. PCs and electronic office equipment will produce heat which will add to room temperature. We are happy to provide free advice over the phone to estimate the number of units and the type of air conditioning you are likely to require.
Hire can be agreed for a daily or weekly basis for a special event or any temporary cover. We also provide monthly and even yearly hire to cover your business or long term server room requirements.
We can offer this service if your business needs dictate. Installation however is always carried out with minimum disruption.
Other than normal wear and tear, you are responsible for any loss or damage once the units are installed. Should there be complete loss of a unit then this will be taken into account on your order. During the hire of the portable unit/s and until collection or despatch to us, their safekeeping is your responsibility.
This is possible providing we are informed and agree to the move in advance. You will need to fax or email us to give us details of any movement proposed. When the units are collected at the end of the hire, they will be collected from the original location or as agreed.
The period that you wish to hire affects the cost charged for the service, providing that you have hired for the minimum agreed period then you may finish the hire or choose to continue hiring at the same rate until it is no longer needed. To terminate the hire you need to notify by email, fax or letter then the contract will be concluded. Hire periods are in full weeks. We will collect the unit/s shortly afterwards, at a pre-agreed time and the units collected from your premises.
