Application of ground-air heat pumps in HVAC systems of apartment and office buildings. Heat recuperation
The heating, ventilation and air-conditioning (HVAC) system of a cottage is shown in figure 4.2. The HVAC system main elements are central sectional air conditioner, Continue reading
Ground-to-air heat pump
To analyze this type of pump let us consider the example of heat pump with a system of heat take-off from the closed ground (i.e. a cooling medium is circulated in a closed loop, thus taking off the low-grade heat) and with a horizontal ground manifold.
The ground, as known, is the most universal source of dissipated (low-grade) heat, since Continue reading
Water-to-water heat pump. Geothermal heat take-off via apertures
Let us consider an example of the open-type heat pump with low-grade heat take-off system in this article. The ground water, coming into the heat pump evaporator directly from an aperture, is a cooling medium (i.e. a medium, which is cooled down to give off its heat). Continue reading
Air-to-air heat pump
In heat pumps of the given type the aerothermal environmental energy is taken off the outside air and, owing to transformation and transfer, heats the indoor air.
The example of heat pump application is Continue reading
