| | | 9. COMPRESSOR COOLING | | |
| | | |
| | | An adequate heat removal mechanism from both the electronic driver and the compressor is fundamental for an optimal performance and reliability of the unit. The cooling method should be selected depending on the working conditions of the appliance, with major factors being the compressor speed and the evaporation temperature, and also, but secondary, the condensation temperature. FREE AIR CIRCULATION OVER THE COMPRESSOR AND THE ELECTRONIC DRIVER MUST ALWAYS BE GUARANTEED. | | |
| | | |
| | | Table 6 shows the recommended cooling method for a standard condensation temperature of 55°C. The table should be taken as a recommendation, as the only way to validate a design is testing the appliance at the highest evaporation, condensation and ambient temperature, verifying that the electronic driver overheat protection does not act. | | |
