Toilet Ventilation System

Product Details

Product Description

Toilet Ventilation System requirements in the commercial & residential industry present specific design challenges, in particular, running costs are more often than not of the highest importance, without guest comfort levels being compromised.

Hotel guests will be reluctant to accept compromises in temperature, service or quality of the environment that would allow the hotel to reduce its energy consumption.

Different types of hotels, office restaurant,residence,commercial & residential industry whether for families or business users will also have different occupancy rates, which can have a significant impact on the sizing of central plant and public space areas- For example, a business hotel will have a full occupancy level at between 1.1 and 1.3 persons per room, whilst a family or resort hotel would have a much higher occupancy, ranging from 1 up to at least 2.0 persons per room. Equally, a rate of 2.4 persons per room may not be unreasonable for a busy budget hotel near to an airport.

No matter or what type of hotel, there are three principles areas within a hotel guest bedrooms, which include en suite bathroom facilities, public and 'back of house' or staff areas.

Each of these would need to be served in a different approach for ventilation requirements, with differing operating schedules.

Guest bedrooms

The environmental control tor guest bedrooms needs to be clear and responsive providing 2-4 air changes per hour. In order to comply with building regulations, minimum extract rates for bathrooms is 15 1/s but many hotels use higher values such as 25 l/s, providing 10-15 air changes per hour in the bathroom, balancing the supply of fresh air for two occupants in the room. Where there are higher rates, tempered air is usually supplied directly to the room. Some hotels will provide higher values to ensure condensation in bathrooms is minimised, whilst improving general air quality. The supply location needs to be positioned to reduce the likelihood of draughts over the bed and in areas that may be used by the occupants when walking to and from the bathroom. It is common to keep the bedroom supply and bathroom extract systems running continuously to maintain room air quality and to ensure adequate extract from the unusual hours.

Public areas

Reception areas (3~5 air changes p/hr), conference facilities (6~10 air changes p/hr), bars and restaurant areas (1(}.15 air changes p/hr) are characterised with high, but variable occupancy levels and lighting loads. The ventilation system should be responsive and capable of delivering high quantities of fresh air when required.

Staffing areas

In essence, staff areas are likely to include offices, kitchens, laundries or linen handling, staff changing, staff dining, training, IT and computer rooms and will hence require ventilation systems specific to different applications. Office and administration areas are usually treated much the same as public areas. It is common for the kitchens to be cooled effectively, at least in part, so that salads, pastries and deserts can be well presented and that the general cooking area does not become too uncomfortable.

Whilst many hotels contract out laundry requirements, linen handling space 13 still required. These areas require high air change rates to remove the high levels of dust and lint that will be generated during the sorting and stacking of linen - it is recommended that at least 15 air changes per hour is reasonable. Consideration should be given to linen chutes, which also generate high dust levels in the collection room.
