Detailed Description
The utility model is further illustrated by the following examples in connection with the accompanying drawings.
Example 1
Referring to fig. 1 to 4, an adjustable phase change heating apparatus of electric heating coupled with solar heating includes a heater 1, a solar heat collecting pipe 9 and a circulation pump 10.
The heater 1 comprises a shell 4, a partition 5 is arranged inside the shell 4, and the inner cavity of the shell 4 is partitioned into a first cavity 6 and a second cavity 7 through the partition 5.
The first cavity 6 and the second cavity 7 are provided with a heat source coil pipe 2, a cold source coil pipe 3 and heating rods 8, the heating rods 8 are arranged in a staggered mode, the whole first cavity 6 and the whole second cavity 7 are symmetrically designed, and the number of the heat source coil pipes 2 is generally two and distributed on two sides of the cold source coil pipe 3.
The first cavity 6 and the second cavity 7 are filled with heat conduction oil and phase change capsules, and valves are arranged on the heat source coil pipe 2 and the cold source coil pipe 3.
Referring to fig. 4, the solar heat collecting pipe 9 and the circulating pump 10 are connected in series through a pipeline to form a circulating passage 11, the heat source coil 2 of the first cavity 6 and the heat source coil 2 of the second cavity 7 are connected in parallel on the circulating passage 11 through a pipeline, and heat conducting oil is filled in the circulating passage 11.
Working principle:
the electric heating is mainly performed at night when the electricity price is low, and the solar heating is assisted in daytime.
In the period of low electricity price at night, the heating rod is used for heating and storing heat simultaneously as the first cavity 6 and the second cavity 7, and at the moment, the cold source walks the first cavity 6, and the first cavity 6 stores heat and heats the cold source.
And when the electricity price is recovered in the daytime, the electric heating is stopped, the heat stored in the phase-change capsules in the first cavity 6 is used as a cold source for heating, and when the heat in the first cavity 6 is insufficient, the cold source is transferred away from the second cavity 7, and the heat stored in the phase-change capsules is used as the cold source for heating.
Solar energy is utilized to assist in heating in daytime, and heat is stored for the first cavity 6 and the second cavity 7. If only one cavity is used, the temperature difference between the cold source and the phase change capsule is larger just at the beginning, and the temperature of the outlet of the cold source is far higher than the set temperature, so that energy waste and insufficient later heat are caused, and the temperature of the outlet of the cold source is too low.
After the two cavities are utilized, when the outlet temperature of the cold source in the first cavity 6 is lower, the cold source is converted into the second cavity 7 to heat the cold source.
The alternating use of the first cavity 6 and the second cavity 7 and the alternating use of solar energy and electric heating in the time period can keep the outlet temperature of the cold source relatively stable, and meanwhile, the energy cost is greatly reduced by using low electricity price and solar energy at night.
Compared with the traditional heater 1 only adopting a single heating cavity, the utility model can switch the two parts of heating cavities back and forth by different time periods and utilize the phase change capsule pair heat accumulating inside to cool source, which not only can ensure the stable temperature of the cool source outlet, but also greatly reduces the energy cost, which can not be achieved by the traditional heater 1 adopting a single heating cavity.
Example 2
This example was further optimized on the basis of example 1, in particular:
the embodiment also comprises a controller and a temperature sensor, wherein the controller is a PLC controller or a PC computer.
The temperature sensor is arranged at the outlet end of the cold source coil pipe 3, the valves on the heat source coil pipe 2 and the cold source coil pipe 3 are all electric control valves, the electric control valves are electromagnetic valves, and the electric control valves, the temperature sensor and the heating rod 8 are all connected with the controller.
The temperature is acquired through the controller, the electric control valve is controlled, an automatic temperature control switch can be realized, and compared with the traditional temperature measurement and manual valve opening and closing, the automatic temperature control valve is higher in degree of automation and more convenient to use.
Example 3
The embodiment is further optimized based on the embodiment, and specifically comprises the following steps:
the shell of the phase-change capsule is made of metal, the heat storage material in the phase-change capsule is aluminum ammonium sulfate dodecahydrate, the traditional phase-change material has the biggest defect of low heat conductivity, and the heat conduction is improved by utilizing the phase-change capsule structure of the aluminum ammonium sulfate dodecahydrate encapsulated by the metal shell.
