Templates – Enhance AWHP plant template to support plants with polyvalent (SHC) units

[AntoineGautier]

Description

This ticket is to track the enhancements of Buildings.Templates.Plants.HeatPumps.AirToWater to support new plant configurations with polyvalent units, as specified in the proposed G36 Addendum L (status: committee comments under review).
The specified configurations are:

• Plant with 2-pipe reversible heat pumps and 4-pipe polyvalent units

  • Addendum L specifies the SOO for a single 4-unit unit but the template should ideally support an arbitrary number of those, and plants with only 4-pipe polyvalent units as well.

• Plant with modular polyvalent unit

  • Addendum L specifies the SOO for a single modular unit (with an arbitrary number of modules). The template will be limited to single-unit support as well.

The proposed plant types are as follows.

type Plant = enumeration(
  HeatingOnly
   "Heating-only with non-reversible heat pumps",
  Reversible
    "Heating and cooling with reversible heat pumps",
  ReversibleHeatRecovery
    "Heating and cooling with reversible heat pumps and heat recovery chiller",
  ReversiblePolyvalent
    "Heating and cooling with reversible heat pumps and polyvalent (SHC) units",
  Polyvalent
    "Heating and cooling with polyvalent (SHC) units")
  "Enumeration to specify the type of plant";

The template should preserve compatibility with all pumping configurations currently supported for 2-pipe AWHP plants:

• Primary-only or primary-secondary
• Dedicated or headered primary pumps
• Variable speed or constant speed primary pumps for constant primary-variable secondary plants
