\u2013 The immediate pre W.W.II years was a period of ever increasing expectations about the winter comfort that was now available for the Canadian home \u2013 for all those that could afford it. With the development of the forced air furnace, \u201cthe winter air conditioner\u201d, came many new possibilities for winter comfort. Included were, automatic combustion control for solid and liquid fuels [coal and oil], automatic room temperature control, air distribution [well beyond that possible with natural convection], constant air circulation. air filtration, as well as automatic humidification. These features would be promoted with great success by the warm air sector of the industry, as a competitive edge, over the \u201chot water heating systems [hydronic systems] of the times \u2013 once considered the preferred type of central heating for all that could afford it.
\u2013 By the mid 1930\u2019s many Canadians had become used to the new automated, in-door comforts now possible for the home. They had become used, also, to the glass stem thermometer conspicuously mounted on the wall thermostat and would check it regularly to make sure their heating system was operating properly. But what was new, here, with the advent of the \u201cwinter air conditioner\u201d, with forced air circulation, was the suggestion that temperature and humidity conditions should be more or less uniform throughout the entire home, not merely at the thermostat.
\u2013 With the marketing and popularization of such remote temperature and humidity measuring devices, homeowners were being invited to check it out for themselves. They were encouraged to purchase a set of scientific air temperature and humidity measuring instruments, make their own scientific measurements and consequently make such changes in the operation of the system, largely by opening and closing registers and dampers, as needed to bring the entire home into one uniform comfort zone. Needless to say many would quickly find the limitations of the new technology \u2013 for automatic zone control was still several decades away for most Canadian\u2019s with forced warm air heating systems.
\u2013 There was a sense that local heating technicians, such as Howard Oliver, Aurora, in marketing temperature and humidity, dial read-out devices such as these, was inviting the home owner to be part of a new \u201cdo it yourself generation\u201d. They were invited to take their own scientific measurements and make their own adjustments, within their own ability and that of the system to respond.<\/p>\n\n\n\n
\u2013 The 1930\u2019s and 40\u2019s would be a period characterised by much research in the field of in-door human comfort, its necessary and sufficient conditions and the means of creating it in Canada\u2019s climate of weather extremes. Warm air heating research would become a legitimate topic for university, as well as industrial research with technical papers and how-to-do-it manuals to follow. In the field of winter humidity control, for example, see \u201cWinter Air Heating and Winter Air conditioning\u201d, John Norris McGraw-Hill 1950, Chapter 9, Humidity and the properties of Air.
\u2013 Characteristic of the period and the emerging market for winter comfort was the creation of the National Warm Air Heating and Air Conditioning Association of Canada [forerunner of the Heating, Refrigeration and Air Conditioning Institute of Canada]. Their extensive set of engineering manuals produced through the 1950\u2019and 60\u2019s would be the standards of the field<\/p>\n\n\n\n
