Cold ton-horse-power-unit conversion-cooler matching knowledge Cold ton (RT): A unit of air-conditioning refrigeration. Cold ton is also known as frozen ton. Frozen ton refers to the energy required to freeze one ton of water into ice. (Note: 1 cold ton is the cooling capacity required to make 1 ton of 0 ° C water into 0 ° C ice in 24 hours.) 1 ton of 0 ° C water can be converted into 0 ° C ice in 24 hours , Frozen tons represent the refrigeration capacity of the freezer. Horsepower (HP): The number of horsepower (PH) in air-conditioning cooling capacity is calculated in kilocalories or watts (W). Generally speaking, 1PH = 2000 kilocalories, multiplied by 1.16 in international units. Calculate 2500W as the standard 1PH in daily life. 23 represents a small horse; the cooling area is 10-14 square meters. 26 stands for 1 horse; cooling area is 14-18 square meters. 32 represents a small 1.5 horse; the cooling area is 18-22 square meters. 35 represents plus 1.5 horses; refrigeration area is 22-25 square meters
