Hi there, I have a gas refrigeration system run by a bock fk2 compressor. The system is used in a fish hold on a trawler to keep catch chilled around 2 deg celcius. After replacing a damaged compressor the system hasn't been working correctly.
There are 2 banks of pipes in the fish hold connected to the system. Only the first half of each bank of pipes is freezing/chilling. The warmer of the 2 pipes from compressor to cooling area(passing through water pump area to cool) is running very hot and the other pipe which used to frost up before is only mildly cold.
Head unit is set at -1*c. Hp/lp settings are at 250psi first setting, diff at 20psi and third at 18psi. The lp gauge is Reading 35 and high pressure gauge 65 lb per sq inch.
My knowledge on refrigeration is limited. If anyone could give me advice on what the problem could be and how to remedy it. If more info is needed just ask.
