Comparison of Cooling Load Calculations by E20 and HAP Software

A complete air conditioning system has been developed to control ambient conditions such as temperature, relative humidity, air movement, etc. in an economical manner for AlFahad Mosque located Unaizah in qassim region K.S.A. In this paper, the calculations were carried out taking into account the ASHRAE standards. For space references and calculations, the plan is developed by AUTO CAD. After taking the plan investigated the location and materials used for construction, based on the study theoretical thermal load calculations were performed by the E20 Method for number of rooms as per the plan and summarizing. The present plan has one huge room of each floor. Based on the heat load calculations, cfm values were found for number rooms and summarized for entire building. Obtained the cfm for first floor as one room and ground floor as one room and add for total cfm for the AlFahad mosque. The object of the paper is about the cooling load calculation for the AlFahad Mosque at Unaizah Qassim Region Saudi Arabi (K.S.A.). The load calculation is carried out by using E20 Manually and HAP software. Nowadays, people are estimating the load calculation by approximation method i.e. by giving dimensions of building which the sellers are estimating roughly tonnage of refrigeration (market method or ALGhaith company method). These cooling load calculations obtained, which is under or over the comfort condition. To overcome this problem, the cooling load calculated by E20 manual method, HAP software and compared.
