refrigerant piping insulation

REFRIGERATION PIPING Successful Installation of a Refrigeration System is Dependent Upon: 1. Tundra Polyethylene pipe insulation is a flexible and closed cell structure that allows it to function as an efficent insultion. 21 COPPER PIPE- BLUE STRIPE • Hard drawn •A Le TRpCy seamless tubing todetard•Dyhe remove moisture • Factory Sealed •Plugs. Cause:. Insulated suction lines are completed by Schneider Electric’s. With unslit tubular insulation, use a sharp knife to cut the insulation lengthwise on one side, as shown in Figure 12. What are the operating temperatures for the various refrigerant pipes. Why do we Insulate Refrigerant Piping? See Chapters 23, 25, 26, and 27 in the 2017 ASHRAE Handbook--Fundamentals for information about insulation … Owens Corning® SSL II® with ASJ Max Fiberglas™ Pipe Insulation is molded out of heavy density resin bonded inorganic glass fiberglas that come in one-piece, 36" (914mm) long, hinged sections. If we look at table 120.3-A above we see that the thickness requirement changes when we get over 200 F. Some of the VRF/VRV manufactures have stated temperatures above 200 F, which would require insulation that is 2-1/2” thick. Insulation thickness, insulation type … With energy codes getting stricter during each code cycle, and some large lawsuits related to refrigerant piping being improperly insulated, the need to get your insulation right is very important. Adhere insulation directly to the pipe every 12 to 18 feet, at the beginning and ends of run. Its imperative that they install the correct insulation, with the correct thickness, and one that meets the temperature rating and exterior protection requirements. You will find that the CMC & IECC codes along with ASHRAE standards require that insulation installed on the exterior of a building be protected from the sun’s UV rays and the weather. A good example would be when running liquid refrigerant line through the attic area where temperature often exceed 110°F. It is tough & flexible with a smooth and powdered inner surface for say installation on copper pipes used for Split air-conditioning systems and VRV/VRF applications as refrigerant piping insulation. Carefully selected piping insulation is critical to the efficiency of a refrigeration system. Prevent condensation on piping or insulation. Refrigeration applications encompass a variety of operating temperatures, piping materials, space and environmental conditions, refrigerants and fluids – all of which impact insulation selection. Click below to go to the Master List of all commercial resources. How many owners or management companies do you know that re-coat their insulation every 2 to 4 years? // //B.Refrigerant piping shall be sized, selected, and designed either by the equipment manufacturer or in strict accordance with the manufacturer’s published instructions. Sensors / Cameras / Licenses / Accessories. Write CSS OR LESS and hit save. 2. Prevent piping system corrosion; Prevent mold growth from occurring on construction materials. Be aware of pipe expansion and the possible movement of the saddle off the support. This is not what dictates insulation thickness. Owners and property managers need to be aware of the maintenance requirements of any exterior insulation and the signs of a poor installation. If it was, all VRV/VRF manufacturer’s would require 2-1/2” on the high-pressure lines. Product Advantages . Thank you for subscribing to updates from APC by Schneider Electric. LG in their literature on page 37 calls for a temperature rating of 227 F. You can see that knowing the VRF/VRV manufactures requirement for the temperature rating of the insulation can have an effect on the thickness of the insulation required for the same size of pipe in the system. For every layer of Cryogel-Z insulation a vapor barrier is present. VRF manufactures have specified in their engineering and installation manuals temperatures that any insulation used on their system must be rated for. CTRL + SPACE for auto-complete. This opens up another discussion, and that is the awareness of the requirements and enforcement by the regulatory officials. For many of the steam heating distribution pipes in buildings, with an operating temperature greater than 350°F, 5 in. In addition, any heat that enters the refrigerant adds to the superheat and reduces system efficiency. This is not to be considered legal advice, but is for the purposes of bringing to light the need to discuss with your contractor or city officials the proper application of the code covering insulation. obviously the owner or management company didn’t keep up with the continuous application of protective coating from the UV rays or the weather. I don’t know about you but I haven’t seen a lot of that being done. Controlling condensation and moisture on refrigeration cold-water lines is essential for long-term thermal performance. Make sure to use expansion loops where required. In almost every scenario involving a heating pipe, replacing 1/2" thickness pipe insulation with 1" thickness pipe insulation reduces the loss of heat transmission in half. The insulated tape enables simple attachment of PVC pipe insulation on many plumbing systems. I have found that from city to city or from one jurisdiction to another there is no consistency in enforcement. of insulation (such as mineral wool, fiberglass, or calcium silicate) will be required on all pipes except those with a size less than 1 in. We are excited that you have joined the group. Prevent condensation on piping or insulation. See armacell’s technical information bulletin on the “Outdoor Protection of Insulation”. Cryogel-Z has an integral vapor barrier. It’s important that you check the VRF manufactures literature for the required temperature rating of the insulation, as each manufacture differs. Here we describe defects in refrigerant piping insulation, problems caused by defective refrigerant piping insulation, recommended installation practices for refrigerant tubing insulation in building walls or cavities as well as outdoors where exposed to the weather, and interior leaks on & in wall below a split system air conditioner wall-mounted unit traced to missing insulation. For these reasons, suction lines should be insulated with a vapor proof insulation. All Product models, All serial numbers. The biggest impact is for the High Pressure Vapor side of the requirements. Avoid heat gains or losses. Maintain system capacity & efficiency. When is the last time you installed a project with 2-1/2” thick insulation on refrigerant piping for a VRF system? The insulation is tailored to fit for copper and iron pipe … The purpose of this document is to provide a clear communication regarding insulating the external copper refrigerant lines. GREENGUARD Gold Certified. Insulation performs a vital role in limiting heat gains in an industrial refrigeration system, ensuring that the compressor load does not become excessive. Use pipe inserts at Hangers/Attachments points to avoid insulation compression. Crimping the insulation along its refrigerant tubing pathway creates points of less and possibly inadequate insulation. Not sure what happen here, but there isn’t much protection for the piping. OK, so what’s the big deal with VRF Insulation? Also the pipe clamps were incorrectly attached directly to the pipes. refrigerant piping). 22 RED FLAG #1 • Copper Pipe-Blue Stripe. Check the current version of LEED. // Field refrigerant piping and associated drain and condenser water piping for mortuary refrigerators, including required pipe insulation. Those VRF manufactures that have High Pressure Vapor operating temperature above 200 F would require 2-1/2” of insulation. Related Topics . SSL II® with ASJ Max Fiberglas™ Pipe Insulation. A properl y designed and installed refrigerant piping system should: • Provide adequate refrigerant flow to the evaporators, using practical refrigerant line sizes that limit pressure drop • Avoid trapping excessive oil so that the compressor has enough oil to operate properly at all times • Avoid liquid refrigerant slugging • Be clean and dry This will probably … This document describes what is the purpose of Refrigerant Piping Insulation? NPS. Cleanliness of all refrigeration piping is of the utmost importance in the installation procedure.
