How many meters does a 1500 liter refrigerated cabinet coil have?

1 to 2 meters. The refrigerator coil is made of 8mm diameter copper pipe. The first circle is 5-6cm away from the mouth of the refrigerator, and then it is coiled downwards one by one. The interval between each circle is 7cm and the knot is about 10cm from the bottom, so it needs 1 to 2 meters. The 1500-liter refrigerator is an ultra-large-capacity freezer suitable for use in hotels and restaurants.
