Answer by Armando who asked for clarification on the defrost cycle inversion. I believe it is absolutely the best way to defrost, although on larger systems the components to make it start to become expensive, that's why most people prefer the electric heaters at the expense of consumption (same old story) Now to the circuit:
The valve reverse cycle (position 1) allows to reverse the direction of passage of the fluid and the respective role of the exchangers. During the entire duration of the defrost the evaporator becomes the condenser, since it is fed by the discharge gas. The controller of Pego depicted allows you to perform all the functions required for this type of defrost. The solenoid valve (position 2) on the liquid allows to stop the compressor through the mass in vacuum, in order to facilitate the return of oil. (In defrost closed) solenoid valve (position 3) is of the type normally open, its role is to prevent the fluid contained in the liquid receiver flood the condenser, which must ensure the function of the evaporator during the defrost cycle. (In defrost fed then closed) The non-return valves (position 4) directing the liquid through the thermostatic valve in the cell (position 6) during the cooling cycle and through the other valve (reference 7) during defrosting. The filter (position 5) is of the type flow adapter seen that the direction is reversed on it. The thermostatic valve (position randell refrigeration 6) with external equalizer, essential, randell refrigeration given the presence of a liquid distributor and therefore takes into account the pressure drop in the evaporator. Note the regulator goodwill randell refrigeration (position 10) so it is not necessary a thermostatic valve with MOP point thermostatic valve manual (position 7) also called pressure valve, is used only in defrost. (You could also use a thermostatic valve to optimize the power of the capacitor, but in that case it would be mandatory to use a valve MOP to prevent overpressure in thermostatic system during the refrigeration cycle. randell refrigeration Thermostat defrost end (position 8) the same principle of defrosting electrical. Liquid randell refrigeration separator or accumulator (position 9) protects the compressor by the return of liquid in the moment of the inversion loop when the thermostatic valve is very open. And last but not least the regulator ZIP (position randell refrigeration 10) which maintains a constant pressure even after a defrost cycle. A circuit in the cooling randell refrigeration phase.
