There is also provision for editing the weather data as well as adding data for other cities. In addition, it can look up outdoor design weather data for over 2000 cities located around the world. Chvac automatically looks up all cooling load and correction factors necessary for computing loads. The program allows an unlimited number of rooms which can be grouped into as many as 100 air handling systems. The cooling loads can be calculated with either the CLTD method or the new RTS (Radiant Time Series) method. Prints Numerous Color Pie Charts and Bar GraphsĬhvac quickly and accurately calculates the maximum heating and cooling loads for commercial buildings.Rooms May be Optionally Grouped Under VAV Boxes.Allows Virtually Unlimited Number of Rooms.Selects Equipment from ARI/GAMA Databases.Calculates Runout and Main Trunk Duct Sizes.Allows Simultaneous Infiltration and Ventilation.Converts any project from English to Metric units and vice-versa.Calculates in both Metric and English Units.Automates Compliance with ASHRAE Standard 62.Allows 30 Walls, 30 Windows, and 12 Roofs per Room.Transfers data to the EnergyPro and eQUEST programs ( more on using eQUEST with Chvac).The Ps圜hart program can import Chvac system data directly into its Air Handler Model window.

Like the diverter valves, the ports on Jandy check valves are also 1.5”/2” or 2”/2.5”, accepting both pipe sizes, with a spigot or socket connection. The new style of plumbing check valve has a see-through lid, gasket-sealed diverter, and the ability to open it up to replace parts or clear clogs. Use these sample Jandy valve configurations to plan your own pool plumbing design, using 3-way valves to replace ball valves or gate valves.Įqually revolutionary in design are the Jandy Check Valves, introduced in 1998.

Jandy valves revolutionized pool plumbing, making it easy to control two pipes with one valve.

These pool piping plans are also useful for pool plumbing renovations, where you might replace all above ground plumbing, along with new pool equipment. Use these Jandy pool plumbing layouts to visualize how the water is pumped from the pool under vacuum, then through the filter and heater, and back to the pool, under pressure.
