Abstract

The invention relates to a performance testing device of a carbon dioxide refrigeration compressor for trans-critical and sub-critical refrigeration systems. The prior art is improved in the way thata component for pressure regulation and pressure reduction is connected between a compressor exhaust opening and an exhaust flowmeter in parallel; a safety valve component A is arranged on an oil separator; a safety valve component B is arranged on a condenser; a safety valve component C is arranged on a liquid reservoir; a subcooler is connected between a shutoff valve C of an outlet of the liquid reservoir and an electromagnetic valve in series; a safety valve component D is arranged on the subcooler; a refrigerant filling and recovering storage tank is connected between an inlet of a mass flowmeter and an outlet of a shutoff valve E in parallel; a recovering shutoff valve and a recovering electromagnetic valve are arranged at the position of an inlet of the refrigerant filling and recovering storage tank, a filling shutoff valve and a filling electromagnetic valve are arranged at the position of an outlet of the refrigerant filling and recovering storage tank, and a safety valve component E is arranged on the refrigerant filling and recovering storage tank; and a safety valve component F is arranged on a gas cooler. In the invention, most of parts can adopt products of the conventional pressure resisting grade, thereby solving the problem of higher pressure of the whole system, reducing the cost and improving the safety of the system.

Description

technical field [0001] The invention relates to a performance test device for a carbon dioxide refrigeration compressor, in particular to a performance test device for a carbon dioxide refrigeration compressor used in transcritical and subcritical refrigeration systems. Background technique [0002] In recent years, carbon dioxide, as a natural refrigerant, has been more and more widely used due to its advantages of non-pollution and high efficiency. In the carbon dioxide refrigeration equipment, the carbon dioxide refrigeration compressor (hereinafter referred to as: carbon dioxide compressor) is one of the most critical components. The compressor is a factory-assembled machine. Under different operating conditions, different compression principles, and displacements, the cooling capacity of the compressor is also significantly different. A structure in the compressor and a design replacement of a part will affect the final cooling capacity of the machine. Therefore, the ...
