Abstract

A thermal storage material capable of phase transition under normal pressure comprises the components of a mixture of alumina powder and magnesium dioxide powder in arbitrary proportion, an aqueous solution of copper sulfate with concentration of 15%, a surface active agent, borax and sodium chloride in the weight ratio of 100:15-20:1-2:1-2:1-3; and the surface active agent is a mixture of potassium sorbate and sodium sulfate in arbitrary proportion. The material conducts phase transition under normal pressure at 80 DEG C, is applicable to full range general reconstruction and promotion, and has thermal efficiency and high unit heat.

Description

Can the heat accumulating of phase transformation under a kind of normal pressure
Technical field
The present invention relates to a kind of heat storage type air-conditioning technical field, what the heat accumulation rod more specifically to a kind of heat storage type air-conditioning was used heats mixed solution.
Background technology
Gu electricity night of civil power existing heat storage type air-conditioning utilize to heat heat accumulation to heat accumulation rod, then come to indoor heating by the heat of release heat accumulation rod daytime again.The heat accumulation rod liquid used of current heat storage type air-conditioning mainly uses water, phase-change thermal storage under ultrahigh-temperature, thus stores amount of heat, but water ultrahigh-temperature phase transformation heating efficiency is low, and energy consumption is also high, uncomfortable popularization, so need high temperature phase change material (pcm), promote to facilitate the gamut of heat storage type air-conditioning.
Summary of the invention
Object of the present invention is exactly the deficiency for prior art, and provide under a kind of normal pressure can the heat accumulating of phase transformation, and its 80 DEG C of phase transformation at ambient pressure, can promote in the transformation of gamut versatility, and thermal conductance efficiency is high, and units of heat is also high.
Technology solution of the present invention is as follows:
Can the heat accumulating of phase transformation under a kind of normal pressure, each component is by weight, the mixture of aluminium sesquioxide powder and magnesium dioxide powder arbitrary proportion: mass concentration is the copper sulfate solution of 15%: surfactivity drug: borax: sodium-chlor=100: 15-20: 1-2: 1-2: 1-3; Described tensio-active agent is the mixture that the arbitrary proportion of sour potassium and sodium sulfate is ploughed on mountain.
Described each component is by weight, the mixture of aluminium sesquioxide powder and magnesium dioxide powder arbitrary proportion: mass concentration is the copper sulfate solution of 15%: surfactivity drug: borax: sodium-chlor=100: 20: 2: 1: 3.
Beneficial effect of the present invention is:
After testing, it at ambient pressure, temperature condition 80 DEG C just can phase transformation, and heat is 156.6KW/ cube.Heating efficiency is high, and units of heat is also high.
embodiment:
Embodiment: can the heat accumulating of phase transformation under a kind of normal pressure, each component is by weight, the mixture of aluminium sesquioxide powder and magnesium dioxide powder arbitrary proportion: mass concentration is the copper sulfate solution of 15%: surfactivity drug: borax: sodium-chlor=100: 15-20: 1-2: 1-2: 1-3; Described tensio-active agent is the mixture that the arbitrary proportion of sour potassium and sodium sulfate is ploughed on mountain.
Described each component is by weight, the mixture of aluminium sesquioxide powder and magnesium dioxide powder arbitrary proportion: mass concentration is the copper sulfate solution of 15%: surfactivity drug: borax: sodium-chlor=100: 20: 2: 1: 3.
Principle of work: use water as the liquid phase ratio in heat accumulation rod with prior art, the present invention after testing, it at ambient pressure, temperature condition 80 DEG C just can phase transformation, and heat is 156.6KW/ cube.Heating efficiency is high, and units of heat is also high, can the transformation of gamut versatility promote.
