`plant_loop_prm_baseline_condenser_water_temperatures` for 90.1-2019

[JanghyunJK]

I can see this section from 90.1-2019:

but I don't think I'm finding the relevant code in os stds here. I did find the relevant code under 2013 subclass though:

openstudio-standards/lib/openstudio-standards/standards/ashrae_90_1/ashrae_90_1_2013/ashrae_90_1_2013.PlantLoop.rb

Lines 10 to 40 in 4299746

	def plant_loop_prm_baseline_condenser_water_temperatures(plant_loop, design_oat_wb_c)
	design_oat_wb_f = OpenStudio.convert(design_oat_wb_c, 'C', 'F').get
	# G3.1.3.11 - CW supply temp shall be evaluated at 0.4% evaporative design OATwb
	# per the formulat approach_F = 25.72 - (0.24 * OATwb_F)
	# 55F <= OATwb <= 90F
	# Design range = 10F.
	range_r = 10
	# Limit the OATwb
	if design_oat_wb_f < 55
	design_oat_wb_f = 55
	OpenStudio.logFree(OpenStudio::Info, 'openstudio.standards.PlantLoop', "For #{plant_loop.name}, a design OATwb of 55F will be used for sizing the cooling towers because the actual design value is below the limit in G3.1.3.11.")
	elsif design_oat_wb_f > 90
	design_oat_wb_f = 90
	OpenStudio.logFree(OpenStudio::Info, 'openstudio.standards.PlantLoop', "For #{plant_loop.name}, a design OATwb of 90F will be used for sizing the cooling towers because the actual design value is above the limit in G3.1.3.11.")
	end
	# Calculate the approach
	approach_r = 25.72 - (0.24 * design_oat_wb_f)
	# Calculate the leaving CW temp
	leaving_cw_t_f = design_oat_wb_f + approach_r
	# Convert to SI units
	leaving_cw_t_c = OpenStudio.convert(leaving_cw_t_f, 'F', 'C').get
	approach_k = OpenStudio.convert(approach_r, 'R', 'K').get
	range_k = OpenStudio.convert(range_r, 'R', 'K').get
	return [leaving_cw_t_c, approach_k, range_k]
	end

so, I'm assuming the same subclass should be available under 90.1-2019? or if it is unavailable in 2019, will it crawl back to find the method from 2013?
