  • Cooling means the removal of heat. In HVAC, a cooling process is usually identified as one which lowers the temperature or humidity (or both) of the ambient air. The effective temperature includes not only the temperature and humidity of the ambient air but also radiant effects and air movement. Some adiabatic cooling processes, i.e., evaporative cooling, do not actually remove any heat, but create a sensation of cooling by lowering the sensible temperature of the air.

  • Spirax Sarco recirculating feedwater spray systems type RFS are designed to provide additional flash steam condensing capacity on boiler feedtank applications. When the condensate return flowrate is high and the cold make-up flowrate is intermittent it is likely that valuable flash steam will be lost through the vent. To ensure that this flash steam is condensed it is often worthwhile to take feedwater from a relatively cool part of the feedtank and pump it to a spray nozzle.

  • All solutions to engineering problems start with a calculation or estimation of the duty which must be met (i.e., quantifying the problem). The purpose of heating and cooling load calculations, then, is to quantify the heating and/or cooling loads in the space(s) to be conditioned. Rough estimates of load may be made during the concept design phase.

  • All air-handling units (AHUs) and many terminal units, if they are not self-contained, require a source of heating and/or cooling energy. This source is called a central plant, and the means by which thermal energy is transferred between the central plant and the AHU is usually a fluid conveyed through a piping system. The fluids used in HVAC practice are steam, hot or cold water, brine, refrigerant, or a combination of these. The equipment used to generate the thermal energy is described in Chap. 7. In this chapter we discuss the transport systems. ...

  • By definition, air conditioning involves control of the air temperature, humidity, cleanliness, and distribution. It follows that an air-handling unit (AHU) of some kind is an essential part of an air conditioning system, though not necessarily of a heating-only system. The function of the AHU is to provide air at a quantity, temperature, and humidity to offset the sensible and latent heat gains to the space (in the cooling mode) and the heat losses (in the heating mode), while maintaining the required temperature and humidity in the space....

  • The design and construction of central plants for heating and cooling is one of the most challenging and interesting aspects of the HVAC design profession. Central plants range in size from small to very large, from residential to industrial utility scale. There are many areas of individual expertise and many levels of competence among designers.

  • Heating is the first word in the acronym HVAC. It is the most important part because without heating mankind would have difficulty in surviving. Proper design of the heating system is even more critical than that of ventilation or cooling. Human history began to develop with the discovery and control of fire which increased people’s ability to survive in a harsh environment.overy and control of fire

  • The flashcards-although there aren't enough of them-are very cool in pointing out the common errors that students make on SAT I math problems. (I made a bunch of them myself, sad to say.) The McGraw-Hill guide uses a method that really focuses on the reasoning skills that are the basis of the SAT I, AND ACTUALLY TEACHES YOU THOSE SKILLS!! Unless you have looked at all of these books as I have, you don't know how refeshing that is! The "College Hill Lesson" format is incredibly clear and easy to follow, and helps students to actually become better readers, writers...

  • AbstractHumidity is one of the main causes of decay in buildings, particularly rising damp, caused by the migration of moisture from the ground through the materials of the walls and floors via capillary action. This water comes from groundwater and surface water. The height that moisture will reach through cap illary action depends upon factors such as the quantity of water in contact with the particular part of the building, surface evaporation conditions, wall thickness, building orientation and the presence of salts.
