NiCd, NiMH. Conditions That Can Cause High Discharge Pressure. High Discharge Temperature Just wondering what your opinions were on running your liquid and suction lines together as a heat exchanger for medium temperature coolers. Discharge of 1 st stage is passed through a water cooled inter cooler and outlet is fed to second stage. Is the intercooler as fouled as the cylinder jackets? Today I found a condensing unit running at 265 degrees discharge temp. Figure B high discharge temp of air compressor high discharge temp of air compressor terrorist (Mechanical) (OP) 31 Aug 14 05:14. 5. 2. Its a two stage double acting reciprocating compressor. Lead acid –20°C to 50°C (–4°F to 122°F) –20°C to 50°C (–4°F to 122°F) Charge at 0.3C or lessbelow freezing. With refrigerant undercharge you will have low head pressure but hi discharge temperature. Charge temperature. 0°C to 45°C (32°F to 113°F) –20°C to 65°C (–4°F to 149°F) Charge at 0.1C between –18 °C and 0°C. High condensing temperatures do not necesseraly increase head pressure. This Regulation establishes ecodesign requirements for the placing on the market of fluorescent lamps without integrated ballast, of high intensity discharge lamps, and of ballasts and luminaires able to operate such lamps as defined in Article 2, even when they are integrated into other energy-using products. CN802 QCN27 RED t. Check Point 2 . High temperatures yield higher capacity (see Figure C) but have a detrimental effect on life. This is the same as a clogged drier, restriction in liquid line defective TXV bulb, high superheat,etc. Safe temperatures have Should the discharge temperature exceed 250 degrees F, the system will likely begin to fail. This causes rings, pistons and cylinders to wear resulting in blow by, leaking valves, and metal debris in the oil. Air or non-condensables in system. 1. A dirty condenser raises the condensing tempera-ture (and pressure), resulting in even higher dis-charge temperatures. The max suction temperature that a booster can handle and still operate without shutting down on high discharge temperature would be somewhere in the 120-130˚F range. Discharge temperature. The three causes for high discharge temperatures are: High condensing temperature. Figure A Typical effects of discharge rate on battery capacity. 4. 3. The high limit temperature is always a maximum of 250 degrees F, but 225 degrees F is a more favorable high end temperature. Hi all we have a khosla make air compressor installed in our unit. Upvote (0) Downvote (0) Reply (0) How about the interstage temp? A restriction in the high-pressure line between the compressor and the receiver tank. What causes high discharge temperature? Check coil of EEV Remove connector, check each winding resistance Of Coil Read wire White - Red Yellow - Red 2. Restricted airflow across condenser. High suction vapor temperature, resulting from underfeeding TEVs. Failure will be in worn rings, acid formation, and oil breakdown and “carbonization” of the oil. Charge advisory. ... Lubrication problem and also when the air compressor is running with high discharge pressure than what required at the end use. High ambient temperature. A high suction temp at any cylinder will result in high discharge temp at that cylinder. Dirty condenser fins etc. If the valves are ok, then it is likely piston rings, assuming your suction temp is ok. 12/5/0511:24 AM. roots are in excessive discharge temperatures. I checked my superheat at the coil and it was 5 degrees. Lower V-threshold by 3mV/°C when hot. Colder operating temperatures will yield a little extra life, but also lower the capacity of lead acid cells. The superheat at the compresor was 65 degrees. The higher suction tempera-ture increases the discharge temperature. 1. H igh discharge tem perature is the resu lt of temperatures in the compressor head and cylinders becoming so hot that the oil loses its ability to lubricate properly.
