'The pressure in the system shall be built up gradually and monitored by remote calibrated gauge or other indicator located in a safe place.' ...Absolutely there is pressure in the air conditioning or heat pump system when the compressor is not running. When the compressor shuts off the high side pressure is high - say 200 and the low side low - say 20 (these are just conceptual as actual pressure depends on the compressor, ambient temperature, refrigerant type).A high volumetric capacity also means less gas in a system for the same cooling results from R410A, making R32 more efficient. The running pressure is fairly similar to R410A so there should be no real difference in operating pressures when checked with gauges. In terms of transportation, the 'mildly flammable' R32 is no different to moving ...The amount of sub cooling can be determined by referencing the bubble temperature column.
