Embodiment Construction

[0029] The present invention will be further described below in conjunction with drawings and embodiments.

[0030] like figure 1 The performance automatic matching tester of the refrigeration equipment shown includes a negative pressure refrigerant bottle, a refrigerant bottle, an array of throttling parts and four check valves. There are 70 parallel branches in the array of throttling parts, and each branch It includes a solenoid valve and a short throttle tube. The throttling component array has one inlet and three outlets. The negative pressure refrigerant bottle and the refrigerant bottle are connected in parallel to the second outlet through the pipeline, and the inlet is connected to the first unit through the pipeline. The reverse end of the one-way valve, the first outlet is connected to the positive end of the second one-way valve through the pipeline, the reverse end of the second one-way valve is connected to the positive end of the first one-way valve through the ...

Abstract

The invention discloses an automatic performance matching experimental instrument for refrigeration equipment. The automatic performance matching experimental instrument comprises a negative-pressure refrigerant bottle, a refrigerant bottle, a throttling part array and four one-way valves, wherein a plurality of parallel branches are arranged in the throttling part array; each branch comprises a solenoid valve and a throttling short tube; and the throttling part array is provided with an inlet and three outlets. The invention also provides a matching method of the automatic performance matching experimental instrument. The automatic performance matching experimental instrument and the matching method have high matching efficiency; in addition, the refrigerant equipment achieves maximum refrigerating and heating amount and maximum energy-efficiency ratio.

Description

technical field [0001] The invention belongs to the technical field of refrigeration experiment equipment, which is used for the design and research experiments of household refrigeration equipment, commercial air conditioners or other refrigeration equipment, and in particular relates to an automatic performance matching experiment instrument for refrigeration equipment and a matching method thereof. Background technique [0002] At present, large-scale refrigeration equipment manufacturers are experimenting with using short throttle tubes with better performance, more convenient use, and lower cost to replace capillary tubes as throttling components. There is a large variance in performance, making substitution more difficult to implement. [0003] Refrigeration equipment research, design, production units, and enterprises, when matching the performance of refrigeration equipment, if the outdoor unit, indoor unit, and compressor are determined, the performance matching pro...
