LPA® Model 925 15 to 75 GPM Liquid Pressure Amplification

925-ss-075-v1.1SM

Model 925 designed with minimal floor space in mind, this low foot print assembly makes it ideal for systems that suffer liquid line distribution issues or higher energy and maintenance running costs. Energy savings in the region of 40% is not uncommon and usually found in systems due to design; be that of a recent refrigeration conversion, plant location issue or a system that had previously been running at a higher condensing temperature.

    I service a large cold storage working with 507a and distribution center facility at 37F in Bogata Colombia. The company I work for make the installation of electronic valves from the manufacturer to save in energy consumption. The system is working since 5 weeks and the discharge pressure is set lower. Can you explain me how this system is different?

    Thanks for your post. If I can ask; what is and what was the condensing pressure level maintained at? When next on site; can you measure the pressure and temperature of the liquid at the farthest EEV and get back to us with that information?

    Thanks.

    Hello this is Frank in Bogata. I checked the cooler which is about 300 feet from the compressor set and up 30 feet. At the cooler there is already a sight glass. I can see gas sometime a lot.. I did not collect pressure information because there was no access point to read from my gage.

    It seems like your cold store energy incentive; by reduced head pressure control, has been adversely effected by flash “gas” due to pressure drop in your liquid line. At lower condensing temperatures, this is worsened. This is where our similarities end. As you probably know, flash gas does not produce useful refrigeration effect, it will continue to circulate around the refrigeration system often using up additional compressor staging or capacity controls leading up to higher power bills by doing so.

    thank you for this information. I have some notes about the system-
    the discharge temperature now is 85F and before it is set 100F. They also collect the kw reading every day but cannot see much better the energy consumption with the new equipment. Can you send us information on your sustem?
    Frank.
