Under the armament systems such as high power laser light, radar, electromagnetic pulse, heat load typically exhibits energy concentration, and heat density is very high,
Knock off the features such as making.Now, this kind of cold liquid machine generally requires to solve under limited space, time and power conditions, obtains most
Good comprehensive solution, wherein Cool Storage Technology are used as one of them.In Cool Storage Technology, due to the energy storage of phase-change material for cold storage
Density is far above same volume sensible heat energy storage, so utilization of the countries in the world to cool storage material is also quite paid attention to, especially effectively reduces
The volume of cold-storage device.On the other hand, cold liquid machine cold-storage early stage often uses ice cold-storage mode, and its phase transition temperature is too low,
During compressor cooling, evaporating temperature will often arrive -10 DEG C~-6 DEG C, cold-storage could preferably freeze, can so cause unit
Efficiency is low, high energy consumption.So, more suitably phase-change material for cold storage is found in industry and increasingly becomes focus, special phase transition temperature
The composite phase-change material between 3 DEG C~20 DEG C, to apply to air-conditioning and cold liquid machine field.
At present, the cold liquid machine of specific use is used as coolant using glycol water mostly, it is ensured that unit is in various works
Under condition and environmental condition, condensation phenomenon is not produced.How phase-change material for cold storage to be effectively combined with coolant, played each
From advantage, also as the emphasis studied in cold liquid machine direction.
For example, 1 m3, 66 % glycol waters are down to 0 DEG C from 20 DEG C, can cold storage capacity Q66% ethylene glycol = C·m· △
Glycol water physical parameter is made even samming in the kJ of t=2.97 kJ/ (kg DEG C) × 1095 kg × 20 DEG C=65043, formula
10 DEG C of degree is checked in.If 30% volume is used into phase transition temperature for 6.2 DEG C of phase-change material for cold storage（Such as laruyl alcohol-octanoic acid）, phase
It is about 173 kJ/kg to become latent heat, then phase transformation can cold storage capacity QLaruyl alcohol-octanoic acid173 kJ/kg of=hm=× 264kg=45672 kJ, then
Plus 70% volume glycol water cold storage capacity, then total cold storage capacity is about 91202 kJ.Both compare, and the latter's cold storage capacity increases
Add about 40%.On the other hand, according to ice cold-storage, by more than 6 DEG C under phase transition temperature, the Energy Efficiency Ratio of usual compressor can decline
More than 12%.Therefore, cold-storage will add energy-efficient cold liquid machine future to have larger prospect, wherein the water tank with cool storage function is just
It is the important step that this technology is combined.
