Hello, change the motocompressor of a split air conditioner of 6000 refrigerators, install the equipment and load it with r22 1,400 grams which is what the plate indicates. when put into operation the low pressure (suction) dropped only to 110psi and when checking the high pressure was also eln 110 psi, with a small oscillation. The equipment is a cold hot air conditioner. I checked for possible obstructions in the pipe but found nothing strange. I appreciate your collaboration...

Test in heating mode and comment pressures.
It can be the 4 way valve.

My personal opinion is past coolant ...... in low that pressure is very high should be at 60 to 65 psi and
What amperage do you have in aquaticity and what is the amperage indicated by the manufacturer?

hello, thanks to both, it seems that it is the reversing valve that is failing, producing a kind of bypass between the 3 outputs. Tomorrow I will desolder and convert to cold only what the client wants

What pressure does it indicate in heating?

Responder

Equally 110 high 110 low, does not vary, I manually exited the solenoid but I am almost certain that the reversing valve is not moving, the amount of refrigerant in response to (Jose Diaz Technical) is indicated in the equipment, anyway, if it were past coolant, it would have a high low pressure, and a high pressure above 250 psi or more, my problem is that THE TWO PRESSURES ARE EQUAL, identical, without variation, when turning on the equipment the two pressures lower a little, but they are still the same.

Since it will desolder, test the engine for compression when changing the 4-way valve.

yes yes, I will take advantage and measure the compression and tightness of it

Well: the solution was as follows, the 4-way valve was locked, and I didn't even manage to unlock it manually once outside the equipment.

Hi. Sorry but I don't see the point as a 4-way valve can balance high and low pressures. There is no compressor pumping or it is not starting.

Hi, thanks for your input, apparently the 4-way valve is producing a sort of bypass between the pipes. Tomorrow I'm going to remove the valve, the motocompressor is new

on the other hand, if the compressor was not starting, do you really think that I would not notice? The compressor is not compressing in the proper way it can be. but I prefer to discard it since it is a new compressor, and that I have previously tested outside the equipment.
