Some notes on high pressure hot water heating. F .R.L. Wh:i,te. Journal of the Institute of Heating and Ventilating Engineers. v.l4, n.l33. Sept.-Oct., 1946. pp.2l6-30.

General discussion on the high-pressure high-temperature hot water type of heating in which remarks are made on a comparison of this system with steam heating. The characteristics of

high-pressure high-temperature ｳｹｳｴ･ｭｾ their advantages and shortcomings are discussed. Explanations of some of the points to be considered in the design together with a possible efficiency advantage over steam heat are also outlined. Remarks on the heat carrying capacities of hot water as compared with steam heat

carrying capacities are made.

Suggestion that for temperatures up to 400oF., water is the best transfer mediumJ but for higher temperatures other fluids are

more suitable.

Sizing of pressure vessels for med.ium pressure hot water heating systems. H. Pollak. Journal of the Institute of Heating and Ventilating Engrs. v.21, n.2l9. Nov. 1953.

. The paper deals with medium pressure hot water heating systems pressurized by thermal. expansion of the water in the

system. The ｰｲ･ｳｳｵｲ･ｾｴ･ｭｰ･ｲ｡ｴｵｲ･ expansion relationship for water is summarized and the theoretical basis of the sizing of a pressure vessel is described and discussed. Graphical means for the sizing are given. Special cases are mentioned and some practical and design considerations are added.

The high temperature water system. T.W. Reynolds. Ventilating. v.48, n.9. Sept. 1951. p.86-96.

Heating and

Advantages of high temperature water systems are discussed from the point of view of supplanting steam systems so widely used in America. The'emphasis is on simplicity:> economy and controlabi-lity and points peculiar to hot water systems are dealt with in detail.
