Waterway noise reduction device and noise reduction method for refrigeration equipment

Abstract

The invention discloses a waterway noise reduction device for refrigeration equipment, which comprises a water tank, a main water outlet pipe and a main return water pipe respectively connected to the water outlet and the water inlet of the water tank, a partial pressure pipe, a water inlet ball valve for the main pipe arranged on the main water outlet pipe, and a water pump . A water pressure gauge, characterized in that: at least two ball valves are arranged on the partial pressure pipeline, and the at least two ball valves have a certain valve opening angle. A noise reduction method is also disclosed: set the set water pressure to be achieved by the water pressure gauge of the refrigeration equipment according to the user's needs; only one ball valve is installed in the measuring partial pressure pipeline and the valve opening angle when the set water pressure is reached is taken as the valve opening limit angle ; Adjust the valve opening angles of at least 2 ball valves to be greater than 0 degrees and less than the valve opening limit angle and are unequal or equal to each other; under the premise of reaching the set water pressure, select at least 2 ball valves when the noise decibel number reaches the minimum The valve opening angle is taken as the optimal valve opening angle. The invention solves the problems of frequent maintenance, poor noise reduction effect, short service life and the like.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a water channel noise reduction device and a noise reduction method for refrigeration equipment. Background technique [0002] Industrial refrigeration equipment includes cold source and water pipeline. The method of use is: cool the water in the water tank through the cold source, and then deliver the cooled water to the user equipment through the water pipeline, and return the hot water from the user equipment back to the refrigeration equipment for re-use. Refrigeration, the re-cooled water is sent to the user equipment again through the water pipeline, and the cycle is repeated. In practical applications, the water pressure delivered to the user's equipment often needs to be divided according to the needs of the user. The method of dividing the pressure is to add a pressure-dividing pipeline to the main waterway pipeline and install a pressure-divi...
