Abstract

There are many factors to study in designing sustainable heat pump systems. Among them, the loading calculation dictates the system’s equipment selection. Calculating the loading demand for equipment sizing and selecting high-performance system are important in the process to plan for sustainable energy system. When sizing a heat pump, it is essential to determine the required cooling and heating capacity. To begin, this chapter examines factors affecting the heating/cooling demand for indoor thermal comfort. Key variables of thermal comfort are also discussed. To further investigate energy efficiency, coefficient of performance (COP) is examined. There are several methods that exist in determining COP. Equations and methods to determine COP are investigated. Examples of COP calculation on water-to-water heat pump and air-to-water heat pump are illustrated. The findings indicate that the COP level varies with types of heat pumps.
