| Popis: | The purpose of this paper is to compare between (hand calculation) and HAP programs for building cooling load for thermal comfort, humidity comfort, ventilation, and air filtration. This project is developed to find the best way to apply the concept of (HVAC) system design in Erbil Polytechnic University/ Refrigeration and Air-conditioning Engineering Department.HAP uses the ASHRAE transfer function method for load calculations and detailed 8,760 hour-by-hour simulation techniques for the energy analysis. The aim of this study is to calculate and compare between hand calculations and HAP program. The building consists of two storeys with 19 zones to be conditioned. The international standard is used in the presented study. This paper estimates the cooling load for different climate conditions by using CLTD method for the building. Cooling load such as, people, lighting, infiltration and ventilation heat gain can be easily entered to the MS-Excel program. In addition to other data such as the cooling loads due to walls and roofs. The results show that there are similarities between the two methods. The maximum total cooling load deference between hand calculation and HAP program is 2.1 %. Therefore, the hourly analysis program can be used for any building design to calculate the load and select the systems. |
