TESTS CARRIED OUT ON VARIOUS CAR HEATERS, DEFROSTERS ETC. WITH A VIEW TO OBTAINING INFORMATION USEFUL FOR DE-ICING LAY OUTS. We have carried out tests on - (1) Clayton car heater. (2) Bosch combined car heater and de-icer. (3) Harrison 1937 type car heater. (4) Buick 1938 car heater. (5) Buick 1938 separate de-icer blower. (6) lce and car heater fan and Lucas motor as proposed for projected car heater. to determine - (a) Running speed of motor and fan assembly. (b) Were air pressure head available (i.e. with no delivery) for de-icing ducts etc. The results of the tests are as follows (rotational speed was measured optically). (1) Clayton Heater - Running speed of motor/fan unit. - 1170 RPM. Air Head available taking radial nozzle and blanking off other flow - 0.3" H2O. | ||
