Heat Pump Flow Diagram
A process flow diagram pfd is a diagram which shows the relationships between the main components in a system.
Heat pump flow diagram. Heat pump energy flow. Process flow diagrams are widely used by engineers in chemical and process engineering they allows to indicate the general flow of plant process streams and equipment helps to design the petroleum refineries petrochemical and chemical plants natural gas processing plants and. As they say a picture worth a thousand words. As the name suggests a heat pump transfers or pumps heat from one place to another notice the use of the word pump heat is not generated but rather is moved.
Heat pump flow controller field supplied full port ball valve each heat pump must include p t ports to verify flow rates lwt ewt heat pump flow center ewt lwt lwt ewt to ground loop heat pump heat pump field supplied full port ball valve for balancing field supplied check valve to prevent short cycling. The expansion valve acts as a metering device regulating the flow of the refrigerant as it passes through the system allowing for a reduction of pressure and. The part of the heat pump system that reverses the flow of refrigerant allowing the system to operate in the opposite direction and switch between heating and cooling. As the illustration shows an electric heat pump can deliver more heat to a house than burning the primary fuel at 100 efficiency inside the house.
A wshp contains all the components of a refrigeration circuit including one or. You can also view the 2 modes showing the refrigerant states with buttons 4 and 5. The electric heat pump can overcome the thermal bottleneck imposed by the second law of thermodynamics for the purpose of heating a house. Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump air conditioning and refrigeration systems.
The heat pump is very simple once you understand the basic concept and i promise you will after reading this. The diagram below shows a heat pump piping layout. Sys apm010 en water source and ground source heat pump systems 1 overview of a water source heat pump system in a typical water source heat pump wshp system each zone has a dedicated wshp that cools or heats air to maintain the desired temperature in that zone.
