Popis:	The efficiency of the so-called econovent heat exchanging equipment located in the Institute of Laboratory Animal Sciences, Faculty of Medicine, Kagoshima University, was measured as follows: The air velocity was decreased to about 64% of that with the fresh air ducts, but a sufficient air volume was supplied maintaining an air change of 12 times per hour or more. The efficiency of the econovent showed a little difference depending upon air conditioning systems. The average efficiencies were 81%, 75% and 76% for temperature, absolute humidity and enthalpy, respectively. The energy required for the air conditioning in this facility in September 1975 and January 1976 estimated by enthalpy hour almost agreed with that estimated using a calorie meter or steam meter. It was assumed that a total of 63% and 60% energy were saved in the cooling and heating seasons, respectively, using the econovent.
