A Guide To Hotel Air Conditioning:

In a highly competitive hotel air conditioning market, hotel operators need to ensure that they are meeting the expectations of their guests, not least in terms of comfort in the rooms. Increasingly, there is an expectation that rooms will include an air-conditioning system to provide both heating and cooling.

Whilst many hotels have a centralised air-conditioning system with fan coil units in rooms served by central boiler and chiller plant, this is not always a practical option. Nor will a split system air conditioner always be viable, because of the need to mount external units on the wall.

Historically, an alternative to hotel air conditioning has been to use a ‘through-the-wall’ air conditioner but these can pose significant challenges in terms of noise levels, energy efficiency and the visual impact on the exterior of the building. Furthermore, when it comes to replacing older through-the-wall units, these older designs are no longer permitted under European regulations.

The answer is to make use of the latest generation of twin-duct, condenserless heat pump air-conditioners, using ‘monobloc’ technology to avoid the need for an external condenser, instead requiring just two 162 mm diameter holes connecting to the outside. These units are offer significant benefits in the following areas:

Noise levels

Modern condenserless air-conditioners combine high levels of acoustic insulation with quieter compressors to achieve noise levels as low as 27dB  making them the perfect all round unit for hotels allowing guests to have a peaceful nights sleep or minimal background noise when installed in a hotel environment.

Retro-Fit Installation

Condenserless air conditioning units can be retrofitted into many applications where there is a current A/C system.  With no requirement for an external condenser, and extensive pipework,  upgrading an existing split air conditioning system is simple and completed in quick turnaround times.

In avoiding the need for an outdoor unit, condenserless air-conditioners do not require installation of unsightly boxes on outside walls, which certainly detracts from the exterior appearance of the building and, in some situations, would not be allowed under planning regulations.  this type of hotel air conditioning solution saving you costs on installation and improving the aesthetic appearance of your building dramatically reducing the outdoor impact of air conditioning systems and seamlessly integrates into any exterior building design.

WiFi Enabled Control

Large hotels now have the ability the control their air conditioning by WiFi technology. Easy to use app displays current temperature settings and allows the user to change temperature, fan speed, and air flow direction from anywhere at a touch of a button. In applications such as hotel buildings, the reception desk can activate, control, and deactivate each unit in every room depending on the occupancy.  They can warm up or cool down the room before hotel guests arrive,  and ensure the units are switched off when the room is unoccupied saving valuable energy consumption

Zero Downtime During Installation

Many hotel installations benefit from installing the unit without any downtime or disruption to normal service and room bookings limiting the loss of revenue as the hotel’s normal operations are not noticeably disrupted by the installation.

Condenserless heat pump air-conditioners, such as Powrmatic’s Vision are the ideal solution for many hotel air conditioning applications. The latest DCINV version of Vision offers even lower (up to 30%) energy consumption and reduced noise levels (only 27 dBa.  You can also see how the Vision has helped many hotels up and down the country with their own hotel air conditioning solutions by clicking below.
