Air Source Heat Pump Description and Operation: A heat pump is classified according to the source from which it extracts heat‚ i.e. the low temperature heat source. One that collects and utilises thermal energy from the outside air to heat the home and provide domestic hot water is called an air source heat pump. In an air source heat pump‚ outdoor air is drawn into the heat exchanger‚ which contains coils filled with a pressurised refrigerant gas. The refrigerant gas referred to here is

Vacuum is produced by the engine’s piston drawing air from the intake manifold during it’s down stroke. The throttle plate keeps air from freely flowing into the manifold creating manifold vacuum. When the throttle body is opened there’s a collapse or loss of vacuum. This collapse in vacuum is actually an increase in intake manifold air pressure. Vacuum is measured in inches of mercury (in. Hg). A quick snap of the throttle plate should drop the vacuum to around 5 in. Hg (inches of mercury)‚ and
