Embodiment 1

[0047] Embodiment 1: 15.0% cuprous oleate, 12.0% zinc dipentyl dithiocarbamate, 10.0% 4.4-methylene bis(dibutyl dithiocarbamate), 10.0% polydecene are synthesized oil, 1.8ppm siloxane defoamer, and the rest of hydrogenated naphthenic oil are physically mixed in the liquid phase as a refrigeration energy-saving synergist.

[0048] Table 1

[0049]

[0050] As can be clearly seen from Table 1, using the composition of the present invention: the air outlet temperature is significantly reduced; the average temperature difference between the inlet and outlet water is increased; the noise of the unit is obviously reduced, and the power saving rate calculated by the power saving rate evaluation method is 21%.

[0051] Note: Evaluation method of electricity saving rate - comprehensive electricity longitudinal comparison method (comparison of electricity consumption before and after using the energy-saving synergistic composition).

[0052] The formula for calculating the power sav...

Embodiment 2

[0058] Embodiment 2: 12% copper oleate, 8% copper dibutyl dithiocarbamate, 12% N, N-dipentyl dithiocarbamate, 11% PAO6, 2.5ppm siloxane The foaming agent and the remaining amount of hydronaphthenic oil are physically mixed in the liquid phase.

[0059] Table 2

[0060]

[0061] It can be seen from Table 2 that after adding the refrigeration energy-saving efficiency synergistic composition of the present invention, the electricity saving rate is 16.5%.

Embodiment 3

[0062] Embodiment 3: 14% lithium 12-hydroxystearate, 7% cadmium diamyl dithiocarbamate, 8% 6-bromo-1-(N, N-dibutyldithiocarbamate ), 6% PAO8, a concentration of 2.0ppm siloxane defoamer and the rest of the hydrogenated naphthenic oil are mixed in the liquid phase (all components are percentages by mass).

[0063] table 3

[0064]

[0065] It can be seen from Table 3 of this embodiment that in addition to the energy-saving effect, the beneficial effect of current reduction is also obtained.

Abstract

The invention relates to a refrigeration energy-saving synergy composition which is suitable for enhancing the refrigeration effect of a compression refrigeration device, which is characterized by comprising a hydrogenation mineral oil basic component with viscosity of 28.5 to 36.5 mm / s at the temperature of 40 DEG C, a nanometer soft-metal organic salt component, a nanometer transitional soft-metal organic salt component, an acylate component and a hydrocarbon synthesized oil component. The composition is free from corrosion, has the corrosion resistance of grade A in a corrosion test (GB / T5096) at the temperature of 100 DEG C for 3 hours, is dissolved in mineral oil in the present refrigeration machine, has self-repairing function, and has better heat exchanging performance compared with that of the original refrigeration oil; the composition is free from containing phosphorous; and the electricity saving rate can generally reach 10 to 15 percent. The composition is of a refrigeration energy-saving synergy agent with high efficiency, safety and environmental protection.

Description

technical field [0001] The invention relates to a refrigeration energy-saving and synergistic composition, in particular to a refrigeration energy-saving and synergistic composition suitable for compression refrigeration equipment. Background technique [0002] In our country, the maintenance level of refrigeration system equipment is generally in an extensive state, and the refrigeration oil used, especially the refrigeration compressor oil of industrial and mining enterprises, the medium and low-grade base oil accounts for about 50% of the total amount. In addition, the system load is heavy during design. , The energy efficiency of the refrigeration system has been seriously attenuated. According to the survey and statistics of the national star hotel central air-conditioning system by Huicong Business Information, the energy efficiency of the units used for more than 2-3 years generally decreases by more than 25%. Industrial and civil refrigeration systems account for a c...
