Heat is transferred from condensing refrigerant Within the coil to the external damp surface after which into the transferring airstream, principally by evaporation.
Suppliers’ tips and appropriate line sizing charts ought to be followed in order to avoid incorporating warmth to both suction or liquid traces. In substantial suppliers, both kinds of strains can be insulated profitably, specifically if subcooling is utilised.
• Lubricate motors if relevant (most Heatcraft condenser motors are completely sealed ball bearing kind and don't demand lubrication)
