Abstract
Detailed design of air-conditioning and heating system is completed through various decisions on various stages. These stages are divided into three stages, such as "specification and usage of a building", "air-conditioning and heating system, and zoning" and "subsequent stage after decision on each load imposed on various equipments." This paper describes the last stage evaluating method for that. Section 1: The author classified various functions which exist between the stage after decision on each load imposed on various equipments and practical air-conditioning and heating system. Items of the classification are composed of heat exchange, transportation, equipment and its efficiency, etc. Loads, energy consumption by funs and pumps and equipment were classified into fitted items of the classification. Section 2: The author studied function of flow rate which occupied a main portion in energy consumption by funs and pumps. Function of air flow rate is classified into an amount of heat exchange (sensible and latent), satisfaction grade of air stream in a room, variation in sensibility of room environment to difference between load and amount of supply, and eliminating rate of dust and various gases. As for function of water flow rate, only heat exchange was taken into account. Section 3: The author made "a chart for analysis of energy consumption by funs and pumps" in order to show various items of the classification and flow rates of air and water to electric power consumption by funs and pumps, studying supposed air and water systems by means of the chart for analysis mentioned above.
