AT-2821 -- Air-to-Water Heat Pump Chiller System—An Analysis of Variance in Annual Electricity Consumption PDF

For the purpose of conserving energy, it is vitally important to analyze the annual consumption of electricity used in the air-conditioning systems of buildings. For this purpose, a simulation program was developed for calculating the annual electricity consumption of the air-to-water heat pump chiller system of a building's air-conditioning system. Using this program, an analysis of variance was made on the annual electricity consumption of an air-to-water heat pump chiller. As a result, one can determine the quantitative effects on the annual electricity consumption in a Tokyo building caused by the building's structure, internally generated heat, air-conditioning conditions, and method of control of the air-to-water heat pump chiller. Moreover, a simple method to calculate the amount of the annual consumption of electricity was devised.
