Description

The principle of operation of the proposed apparatus for measuring the performance of refrigeration units is based on the direct volumetric measurement of the flowing refrigerant, the accuracy of which the apparatus reads depends on the specific gravity and viscosity of the liquid. A known turning device (a multi-chamber drum placed in a closed chamber connected to the vapor space of a condenser and equipped with a receiver for injecting a liquid agent into it) was used as a measuring instrument for the amount of flowing fluid. In order to convert said chamber into an air separator, a coil was installed in it.

In FIG. 1 shows a vertical longitudinal section of the apparatus; FIG. 2 is the same cross section.

The direct volumetric meter of the refrigerant is made in the form of a rotating multi-chamber drum (Figs. 1 and 2) placed in a closed chamber 24 and consisting of a distribution pipe of three chambers displaced at an angle of 120 ° and closed by bottoms on both sides. In the distribution pipe, supported by their ends on the ball bearings, on the fixed inlet pipe 5 there are horizontal slots 18, 19, 20, cm (273)

Also used at an angle of 120 °, which serves to transfer liquid into one or another chamber of the drum and three tubes 2 to release gas from the chamber filled with liquid refrigerant, to avoid creating a gas buffer in the upper part of the cat that can place the chamber filling liquid.

On the removable flange, under the sight-glass, the rev counter 6:. A swinging mechanism marks every turn of the drum.

The receiver 25 of the apparatus for monitoring the level of liquid therein is provided; measuring glass 7, fixed with its ends in valves 8 with non-return ball valves that prevent refrigerant leakage in case of damage to the glass. Measuring glass 7 is protected by a metal casing 9 to protect it from external mechanical impacts.

Thermometer sleeve 10 is designed to measure the temperature of a liquid refrigerant. The receiver 25 is provided with a bent pipe with an oil drain valve 11 for periodically lowering the oil deposited in the lower part of the vessel.

The grill 12, fixed at the bottom of the receiver 25, serves to prevent the liquid from bubbling from the outflow of the outflow from the drum / t chambers to obtain steady levels of flowing refrigerant both in the receiver 25 and in the measuring glass 7.

The evaporative coil 14, through which the throttled refrigerant passes through the control valve / 5, prevents the gas in the upper part of the vessel from cooling and condensing the refrigerant vapor, relieving the latter of non-condensable gases, which are released through the valve 76 into a glass flask 77 with water.

The apparatus is calibrated with water, for which a rotating drum with an inlet pipe and a rev counter, mounted on a removable flange, can be removed from the upper part of the vessel and, after calibration and appropriate adjustment of their mutual operation, are inserted back, and the lantry is screwed on.

The liquid refrigerant along the underwater pipe 3 (which is simultaneously the axis of the rotating drum) through the holes 4 is inserted into the distribution pipe of the drum /, from which slits 78 enters the chamber 2 /. After filling the chamber 2 / level in the distribution pipe (the liquid will rise, the liquid will flow into the chamber 22, which will cause the drum to turn and simultaneously fill the chamber 22. The chamber 2 / will be emptied through the narrow, 5, running along the whole drum; Thus, the camera 2 / will take the position of the camera 23, and the camera 22-position of the camera 2 /. Each turn of the drum corresponds to the volume content of all three cameras 2 /, 22 and 23.

The subject matter of the invention.
