Cold / heat split does not reach the room cold

Hello good morning forum ... I have a problem with a 3.2W COVENTRY cold / heat split ... which had no gas ... I had lost in the connection nuts ... I cut and welded ... that is solved ... then I pressed with 400 psi nitrogen ... and threw me lost in the reversing valve in 2 of its 3 pipes ... I welded them and pressurized again and never lost again ... I continued to empty the needle did not move .. I broke the void with r22 and started the team. the compressor started and automatically the low pressure stagnated 100 psi ... but the cold does not reach the evaporator ... my doubt would be that the valve could have been clogged ... I really lost my way I could not solve it ... I would appreciate some help

Hi, you can release the coolant if there is little you loaded, loosen pipes and test the engine.

Even if there were problems in the inverter due to no gas flow or having sealed the gas flow in another area, the pressure should be empty, that compressor is not sucking. When you turn off the compressor, what pressure do you have?

When I turn it off the low pressure goes to the limit ... and when I turn it on it goes back to 90 or 100 psi

When it is switched on it is not going to be empty it remains stagnant in that pressure 90 psi

If the gas used by your device is r22a, you are exceeded by gas. This refrigerant works with 65 psi in the suction and high between 230 to 250. Just as you are going to nail the compressor

So what I have to do is take out gas ... and nothing else. At the time I solved the loss to the valve could be leaved

By the time I welded the valve it could have broken inside. "Or the capillary that passes x below." It is the first time I have a job like this ... the compressor starts the fan too ... only the stopcocks cool and nothing more ... the valve raises a lot of temperature

Put the manifold and see it slowly taking gas waiting for the system to stabilize until it reaches 65psi
