Shipping and installation for heating, ventilation, and air conditioning (HVAC)
First Claim
1. A zone-control unit for use in a climate control system, the zone-control unit comprising:
- a thermal transfer assembly having a supply port and a return port;
an inlet piping assembly for supplying fluid to the thermal transfer assembly, the inlet piping assembly having a first passage coupled with the thermal transfer assembly supply port and a second passage coupleable with an upstream fluid source;
an outlet piping assembly for receiving fluid from the thermal transfer assembly, the outlet piping assembly having a first passage coupled with the thermal transfer assembly return port and a second passage coupleable with a downstream fluid destination;
a bracket that maintains the inlet piping assembly and the outlet piping assembly in relative positions appropriate for use in the climate control system;
a first seal comprising a member selected from the group consisting of a cap, a heat spun seal, and a stop valve, the first seal creating a seal by closing the second passage of the inlet piping assembly;
a second seal comprising a member selected from the group consisting of a cap, a heat spun seal, and a stop valve, the second seal creating a seal by closing the second passage of the outlet piping assembly; and
a pressure gauge,wherein a specified quality assurance amount of pressure is present within the thermal transfer assembly, the inlet piping assembly, and the outlet piping assembly, andwherein the pressure gauge is configured to measure and display the specified quality assurance amount of pressure.

Abstract
A zone-control unit adapted for facile inclusion in a building'"'"'s ductwork includes a mechanical terminal unit, inlet and outlet piping assemblies that are mechanically coupled together. The structure also includes at least one handle so the zone-control unit may be conveniently and safely handled both during shipping, and during installation into a HVAC system. Prior to installation into a HVAC system the fully-functional zone-control unit also includes a pair of caps respectively sealing the ends of the piping assemblies, and a pressure gauge for sensing pressurization of the piping assemblies and coil which the caps seal. Sealed in this way a pressure gauge permits testing to assure that the piping assemblies and coil are leak free, and readily assessing that zone-control units remain leak free until they are about to be installed into a building'"'"'s HVAC system.
