We propose a new method for producing ice by winter air in cold regions, and perform tests with an apparatus assembled as trial. The apparatus consists of two parts, a heat exchanger and an ice making part, to get high thermal efficiency.
The tests yield the following results:
1) The production rate of ice is estimated to be 2---19 kg-h-' from the heat intake ability of the ice maker, which was obtained by the tests carried out at refrigerant (25 wt% calcium chloride) tempera-tures of -4.4- -14.5°C at the inlet of the ice maker and at refrigerant flow rates of 1. 0- 5.6 1-min-'.
2) The production rate of ice is 3.5-6.8 kg-h-' in the proof tests, which were carried out at outdoor temperatures of - 5 - -10°C (refrigerant temperatures of 3-8°C at the inlet of the ice maker) and refrigerant flow rates of 1.3-5.2 1-min-1.
