Abstract
Abstract A SPACE IS MAINTAINED BETWEEN 55 AND 85 DEGREES FAHRENHEIT, AND THEREBY BELOW BLOOD TEMPERATURE. THE BOUNDARY WALLS OF THE SPACE ARE REGULATED AS TO TEMPERATURE BY A SENSING DEVICE AND A SECOND SENSING DEVICE RESPONDS TO THE TEMPERATURE AND HUMIDITY OF THE AIR IN THE SPACE AND CONTROLS THE FIRST SENSING DEVICE. IN THIS MANNER, THE RADIANT LOSS FROM AN OCCUPANT OF THE SPACE TO THE WALLS AMOUNTS TO ABOUT 400 B.T.U. PER HOUR MINUS THE HEAT EXCHANGE BETWEEN THE OCCUPANT AND THE AIR WITHIN THE SPACE. THE WALLS MAY BE COVERED BY A DETACHABLE MATERIAL HAVING PASSAGES FOR A HEAT EXCHANGE MEDIUM OR INCORPORATING AN ELECTRIC HEATING FILM.
