Embodiment 1
[0067] Example 1 : 15.0% cuprous oleate, 12.0% zinc diamyl dithiocarbamate, 10.0% 4.4-methylene bis(dibutyl dithiocarbamate), 10.0% polydecene synthetic oil, 1.8 The ppm siloxane defoamer and the rest of the hydrogenated naphthenic oil are physically mixed in the liquid phase as a refrigeration energy-saving synergist.
[0068] Table 1
[0069]
[0070] It can be clearly seen from Table 1 that using the composition of the present invention: the temperature of the air outlet is significantly reduced; the average temperature difference between the inlet and outlet water is increased; the noise of the unit is significantly reduced, and the power saving rate calculated by the power saving rate evaluation method is 21%.
[0071] 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).
[0072] The formula for calculating...
Embodiment 2
[0078] Example 2 : 12% copper oleate, 8% copper dibutyl dithiocarbamate, 12% N,N-dipentyl dithiocarbamate, 11% PAO6, 2.5ppm silicone defoamer, The remainder of the hydronaphthenic oil is physically mixed in the liquid phase.
[0079] Table 2
[0080]
[0081] 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
[0082] Example 3 : 14% lithium 12-hydroxystearate, 7% cadmium diamyl dithiocarbamate, 8% 6-bromo-1-(N,N-dibutyldithiocarbamate), 6 %PAO8, siloxane defoamer with a concentration of 2.0ppm and the rest of the hydrogenated naphthenic oil are mixed in the liquid phase (all components are percentages by mass).
[0083] table 3
[0084]
[0085] 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 refrigerating energy-saving and synergistic composition suitable for enhancing the refrigerating effect of compression refrigerating equipment. Its characteristics include basic components of hydrogenated mineral oil with a viscosity of 28.5 to 36.5mm / s at 40°C, nano soft metal organic salt components, nano transition soft metal organic salt components, organic acid ester components, hydrocarbon synthesis oil component. The composition is non-corrosive, (GB / T5096) corrosion test 100°C.3h is grade 1, compatible with mineral oil in current refrigerators, has self-repairing function of wear and tear, and has better heat transfer than original refrigerator oil; the composition It does not contain phosphorus; the electricity saving rate can generally reach 10 to 15%. It is a high-efficiency, safe and environmentally friendly refrigeration energy-saving synergist.
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, the energy efficiency of the units used for more than 2-3 years generally has attenuated by more than 25%. Industrial and civil refrigeration systems account for a consider...
