2. Nozzle and flapper - Wikipedia

   en.wikipedia.org/wiki/Nozzle_and_flapper

   The nozzle and flapper mechanism is a displacement type detector which converts mechanical movement into a pressure signal by covering the opening of a nozzle with a flat plate called the flapper. [1] This restricts fluid flow through the nozzle and generates a pressure signal.

3. Reversing valve - Wikipedia

   en.wikipedia.org/wiki/Reversing_valve

   Reversing valves are built into the heat pump by the manufacturer, and must be replaced by an HVAC technician if they fail. Since the valve is an integral part of the sealed refrigerant circuit, proper procedures for recovering and then later refilling the refrigerant must be followed, to prevent its loss into the atmosphere.

4. Pipe-in-pipe system - Wikipedia

   en.wikipedia.org/wiki/Pipe-in-pipe_system

   A pipe-in-pipe system [1] is a form of plumbing where all water pipes are running inside another pipe. Its purpose is to ensure that any leaks in the innermost pipe will not leak into the building structure and can be detected, as well as make for easier change of any internal pipes with leakage without opening the walls.

5. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as compared to a mid-efficiency forced-air or forced-draft furnace, is the capture of latent heat from the exhaust gases in the secondary heat exchanger.

6. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
