NiCd, NiMH. A restriction in the high-pressure line between the compressor and the receiver tank. The three causes for high discharge temperatures are: High condensing temperature. Is the intercooler as fouled as the cylinder jackets? 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. High ambient temperature. high discharge temp of air compressor high discharge temp of air compressor terrorist (Mechanical) (OP) 31 Aug 14 05:14. 5. A dirty condenser raises the condensing tempera-ture (and pressure), resulting in even higher dis-charge temperatures. Hi all we have a khosla make air compressor installed in our unit. 4. Should the discharge temperature exceed 250 degrees F, the system will likely begin to fail. Lower V-threshold by 3mV/°C when hot. Dirty condenser fins etc. High temperatures yield higher capacity (see Figure C) but have a detrimental effect on life. 1. This is the same as a clogged drier, restriction in liquid line defective TXV bulb, high superheat,etc. High condensing temperatures do not necesseraly increase head pressure. Figure B 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. 2. If the valves are ok, then it is likely piston rings, assuming your suction temp is ok. 12/5/0511:24 AM. Check coil of EEV Remove connector, check each winding resistance Of Coil Read wire White - Red Yellow - Red 1. Conditions That Can Cause High Discharge Pressure. Discharge temperature. What causes high discharge temperature? 3. CN802 QCN27 RED t. Check Point 2 . 2. The superheat at the compresor was 65 degrees. I checked my superheat at the coil and it was 5 degrees. roots are in excessive discharge temperatures. 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. 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. 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. 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. With refrigerant undercharge you will have low head pressure but hi discharge temperature. This causes rings, pistons and cylinders to wear resulting in blow by, leaking valves, and metal debris in the oil. Failure will be in worn rings, acid formation, and oil breakdown and “carbonization” of the oil. High suction vapor temperature, resulting from underfeeding TEVs. The high limit temperature is always a maximum of 250 degrees F, but 225 degrees F is a more favorable high end temperature. Restricted airflow across condenser. Figure A Typical effects of discharge rate on battery capacity. The higher suction tempera-ture increases the discharge temperature. Upvote (0) Downvote (0) Reply (0) How about the interstage temp? Colder operating temperatures will yield a little extra life, but also lower the capacity of lead acid cells. Today I found a condensing unit running at 265 degrees discharge temp. Charge temperature. A high suction temp at any cylinder will result in high discharge temp at that cylinder. Air or non-condensables in system.
