Light fittings

The effect of ceiling beams and light fittings on ventilation jets was also studied by Holmes and Sachariewicz. Their studies were limited to the two-dimensional case air supply through linear slot and a two-dimensional barrier (Fig. 7.40). Tbe results of these studies show that the ceiling jet can take one of three courses when it encounters an obstruction ... [Pg.481]

Ignition sources in the cupboard and duct system should be avoided. Plastic fans, electrical sockets external to the cupboard, and explosion-proof light fittings reduce the likelihood of ignitions. [Pg.887]

Heat removal luminaire A light fitting provided with an extract duct from which the heat generated within the fitting, and a portion of that generated in the space, is extracted either directly to outside or for recirculation. [Pg.1447]

An electrician went up a ladder to repair a light fitting and was affected by fumes coming out of a vent about a meter away. The electrical hazards and the hazards of working from a ladder were considered, but no one thought about the hazards introduced by the vent—yet vents are designed to vent. [Pg.146]

Example 21.5 The coldroom in Example 21.3 has 12 lighting fittings labelled 280 W. The four evaporators each have three fan motors of 660 W gross per fan and 18 kW defrost heaters which operate alternately for 15 min twice a day. The fork-lift truck is rated 80 A at 24 V and will be in the store 20 min each hour during the 8-h working day. Two packers will be present for 10 min each hour. Estimate the average and peak loads (see Table 21.2). [Pg.219]

Ceiling extract systems are now commonly arranged to take air through the light fittings, and a proportion of this load will be rejected with the exhausted air. [Pg.271]

Example 26.3 Return air from an office picks up 90% of the input of 15 kW to the lighting fittings. Of this return air flow, 25% is rejected to ambient. What is the resulting heat gain from the lights ... [Pg.271]

The method is appropriate for large and small mouldings where very close tolerances and delicate inserts are not required (inserts would be disturbed when the material started to flow). It is used for moulding materials such as aminoplastics, to make bottle caps, electrical and light fittings, and tableware. [Pg.152]

In this chapter, financial aspects - independent of safety related data - are given priority, e.g. the comparison between e - and d -motors or light fittings. [Pg.456]
