A laboratory multifunctional cold and hot water unit test tool

Abstract

The invention discloses a laboratory multi-function cold and hot water unit testing equipment, which includes a four-way pipe and a connecting piece, the connecting piece is connected with the center of the bottom of the four-way pipe, and two adjacent ports of the four-way pipe A plug is screwed and connected, and a round hole is opened at the center of the outer surface of the plug, and a nut ring is fixed on the outer surface of the plug corresponding to the position of the round hole. In the present invention, the laboratory chiller test equipment is designed through the four-way pipe, which can reduce the types of equipment, reduce the number of elbows, and reduce the manufacturing cost of the equipment. By setting the plug and screwing the connecting stud on the plug, the four-way The criss-cross structure of the pipe, and the automatic exhaust valve connected to the top center of the four-way pipe can ensure the smooth direction of water flow. The test end of the tester can fully contact with water, thus ensuring the accuracy of the experimental measurement.

Description

technical field [0001] The invention relates to the technical field of testing heat pump water heaters, in particular to a laboratory multifunctional cold and hot water unit testing tool. Background technique [0002] In the refrigeration industry, it is divided into air-cooled chillers and water-cooled chillers. According to the compressor, it is divided into screw chillers and scroll chillers. In terms of temperature control, it is divided into low-temperature industrial chillers and normal temperature chillers. , The temperature of the normal temperature unit is generally controlled within the range of 0 degrees to 35 degrees. The temperature control of the low-temperature unit is generally around 0 degrees to -100 degrees. Chillers are also known as: refrigerators, refrigeration units, ice water units, cooling equipment, etc. Because they are widely used in various industries, the requirements for chillers are also different. Its working principle is a versatile machin...

Problems solved by technology

[0003] The existing laboratory cold and hot water unit test equipment is relatively bulky, inconvenient to install, and there are many elbows, the temperature sensor cannot fully contact with the water, and the direction of water flow is difficult to keep consistent, resulting in large test water resistance and temperature test. At the same time, due to the large number of test models, there are many types of tooling, and more experimental tooling needs to be made, which has poor versatility, and there is some inconvenience in the adjustment of the existing laboratory cooling and heating unit test tooling after fixing
