Description
Technical field
The present invention relates to a kind of HTHP electric heater.
Background technology
Current electric heater can be divided into two classes according to the GB range of definition: the one, storage-type electric water heater, another kind of is quick electric water heater, if in conjunction be about to issue the fast hot combined electric water heater of water storage, always have and can be divided into three types.
Wherein, there is following defect in storage-type electric water heater: storage-type electric water heater is limited by the structural behaviour of inner bag in real world applications, the highest water storage temperature generally only can maintain 75 ℃, its energy storage ability mainly depends on the size of storage tank volume, storage tank volume is larger can store more heats, but compact water storage tank increases, and has not only increased the material cost of product, and can cause water heater under low load condition preheating time overlength; In addition, according to the computational methods of hot water delivery rate, storage tank volume increases, and can reduce the hot water delivery rate of water heater.Cost defect high, weak effect cannot meet modern's life fast pace and energy-conservation requirement like this.In order to overcome above-mentioned defect, the application develops HTHP electric heater.
summary of the invention
Technical problem to be solved by this invention is that a kind of HTHP electric heater will be provided, and it can dwindle the volume of existing storage-type electric water heater, reduces material cost, improves the energy storage ability of its hot water delivery rate and unit volume.
No matter the energy storage ability of water, be the water of Living Water or other purposes, will be higher than the energy storage ability under gas phase state in the energy storage ability of liquid phase state.If the specific heat capacity under liquid phase state is " 1 ", and under gas phase state, its parameter is less than " 1 " certainly, the size of specific heat capacity is to weigh the important parameter of heat absorption capacity size, otherwise also can think the standard of unit mass energy storage efficiency.If at present the volume energy storage scarce capacity of storage-type electric water heater to cause the defect that hot water deliverability cannot adaption demand be key problem, not equal to be to have the hysteresis quality of know-why application in its heat accumulation mode.
