Flip-able vav piping package

Abstract

A piping package is provided for connecting a heating, ventilation, air conditioning, and refrigeration (HVACR) system to a building variable air volume (VAV) system. The piping package includes an enclosure containing a supply pipe and a return pipe. Each of the supply pipe and the return pipe include an air vent and a blow-down valve. The piping package can be configured such that it is flip-able and can be positioned on either side of a main unit of the HVACR system. The piping package can further include a heat exchanger configured to exchange heat between the HVACR system and the process fluid distributed to the building VAV system.

         4 . The piping package of  claim 1 , wherein the return pipe includes a control valve including an actuator. 
     
     
         5 . The piping package of  claim 4 , further comprising a bypass line extending from the supply pipe to the control valve. 
     
     
         6 . A heating, ventilation, air conditioning, and refrigeration (HVACR) system, comprising a piping package, the piping package comprising:
 a supply pipe, the supply pipe including a first blow-down valve and a first air vent;   a return pipe, the return pipe including a second blow down valve and a second air vent; and   an enclosure configured to surround the supply pipe and the return pipe, the enclosure including a first access opening configured to allow access to the first blow-down valve and a second access opening configured to allow access to the second blow-down valve.   
     
     
         7 . The HVACR system of  claim 6 , further comprising a heat exchanger, wherein the supply pipe and the return pipe are each connected to a process fluid side of the heat exchanger. 
     
     
         8 . The HVACR system of  claim 6 , wherein the enclosure has a removable side panel. 
     
     
         9 . The HVACR system of  claim 6 , wherein the return pipe includes a control valve including an actuator. 
     
     
         10 . The HVACR system of  claim 9 , wherein the actuator is terminated on a unit controller of the HVACR system. 
     
     
         11 . The HVACR system of  claim 9 , further comprising a bypass line extending from the supply line to the control valve. 
     
     
         12 . The HVACR system of  claim 6 , further comprising a main unit and a control box, wherein the VAV piping package is on a same side of the main unit as the control box. 
     
     
         13 . The HVACR system of  claim 6 , further comprising a main unit and a control box, wherein the VAV piping package is on an opposite side of the main unit from the control box. 
     
     
         14 . A method of installing a heating, ventilation, air conditioning, and refrigeration (HVACR) system at a location, comprising:
 installing a main unit of the HVACR system;   installing a pre-assembled piping package, the pre-assembled piping package including:
 a supply pipe, the supply pipe including a first blow-down valve and a first air vent; 
 a return pipe, the return pipe including a second blow down valve and a second air vent; and 
 an enclosure configured to surround the supply pipe and the return pipe, the enclosure including a first access opening configured to allow access to the first blow-down valve and a second access opening configured to allow access to the second blow-down valve; and 
   connecting the supply pipe and the return pipe to a building variable air volume (VAV) system.   
     
     
         15 . The method of  claim 14 , wherein the pre-assembled piping package is installed in a right-side orientation relative to the main unit of the HVACR system. 
     
     
         16 . The method of  claim 14 , wherein the pre-assembled piping package is installed in a left-side orientation relative to the main unit of the HVACR system. 
     
     
         17 . The method of  claim 14 , wherein the pre-assembled piping package includes a heat exchanger, wherein the supply pipe and the return pipe are connected to a process fluid side of the heat exchanger. 
     
     
         18 . The method of  claim 14 , further comprising installing a heat exchanger and connecting each of the supply pipe and the return pipe to a process fluid side of the heat exchanger. 
     
     
         19 . The method of  claim 14 , wherein the HVACR system includes a control box, and the pre-assembled piping package is installed on a same side of the main unit of the HVACR system as the control box. 
     
     
         20 . The method of  claim 14 , wherein the HVACR system includes a control box, and the pre-assembled piping package is installed on an opposite side of the main unit of the HVACR system from the control box.
