First, the principle of blocking the air cooler: rely on axial fan the air inside the cold store through the cooler in the evaporator with forced circulation, in the evaporator for hot-swap cooling air, thus cooling purposes. Ceiling-mount cooler classification: ceiling-mount cooler installed in cold storage rooms flat-topped, does not take the storeroom. According to the ceiling-mount cooler air supply forms, can be divided into single-sided air supply and ventilation; under its wing form, there are around the chip and chip set. Freon cooler is one-way ceiling set piece, cooling tube for general use-D10-20 of copper tube, their coat 0.2 ~ mm thin aluminium fins. In order to make the ceiling-mount cooler export of refrigerant has certain superheat, cooler in the refrigerant trend and air flows generally use cross flow.
Second, ceiling-mount cooler structural characteristics: 1, ceiling-mount cooler of the evaporator is made of copper tubes and aluminum fins, copper tube using vacuum annealing process, with a high level of cleanliness and bendability, aluminum finned generally use quadratic overturn a stamping process, copper tubes and aluminum fins with mechanical expanding combination firmly close after, with high heat transfer efficiency. 2, ceiling-mount cooler axial fan has a simple structure, stable operation, high efficiency, low temperature resistance, low noise and so on. 3. defrost using stainless steel electric heating, electric heating tube end seal adopt strict processing technology, the electric heating tube not leakage has a longer service life. 4, ceiling-mount cooler shell made of high quality cold plate spray, crimped aluminium or stainless steel plate, from the user selection. Third, ceiling-mount cooler installation instructions: 1, air cooler with 4 or 6 root length bolt lifting roof within the library. 2, installation of ceiling-mount cooler should remain level. 3. flip down the drain piping cooler to gallery should maintain a certain degree of slope, enabling smooth defrosting water out galleries. 4, ceiling-mount cooler inlet branch should not be tightly against a wall to guarantee sufficient air cooler air reflow.
