![]() Heat flow through walls, floors, roofs, doors, glazing. Heat Gains – Can Cycle From ‘Zero’ to ‘100%’ The following contribute to the cooling load:- 1. Note:- overestimation of cooling load – enables operation at higher ambient (but the plant will be marginally oversized).ĥ Heat Gains The following contribute to the cooling load:. a dry bulb temperature of 28☌ may be used for cooling load calculations, but a temperature of 32☌ taken for selecting air cooled plant condensing equipment. It is possible for cooling applications that:- temp☌ determining the cooling load ≠ temp☌ sizing the cooling plant. The selection of design ambient temperatures affects cooling duty These are obtained from established ‘weather data’ (summer time temperatures). Conditions required for thermal comfort will ‘not be met’.Ĭooling Loads Ambient Design Temperatures 1. Overall wasteful Under-sizing Creates:- 1. Operational at part load, generates reduced efficiency 3. Size – Versus - Load Regulation 22 of EPB Regulations “The inspection report must include an assessment of the air-conditioning efficiency and the sizing of the system compared to the ‘cooling requirements’ of the building, and contain appropriate advice on possible improvements to the system, replacement of the system and any alternatives.”ģ Cooling Loads 1.
