Detailed Description
The present invention will be described in further detail with reference to the following examples:
the solar energy-water source heat pump heating system which can obtain heat by means of solar energy and phase change is shown in fig. 1 and fig. 2 and comprises a first coil pipe 7 and a second coil pipe 8 which are arranged in a water pool 6, wherein a circulating medium ethylene glycol aqueous solution is arranged in the first coil pipe 7 and the second coil pipe, the first coil pipe 7 is connected with a water source heat pump 20, and the second coil pipe is connected with a solar heat collecting plate 1. When sunlight is sufficient, the temperature of the circulating medium in the solar heat collecting plate 1 absorbs the heat of the sun to rise, the circulating medium with the increased temperature releases the heat in the second coil 8, the water temperature near the second coil 8 in the water pool 6 rises, the density of the water decreases and the water flows upwards to the vicinity of the first coil 7, and the circulating medium in the first coil 7 absorbs the heat and the temperature rises to provide the heat source heat supply user 11 for heating for the water source heat pump 20.
The circulating medium between the solar heat collecting plate 1 and the second coil 8 and the circulating medium between the water source heat pump 20 and the first coil 7 are ethylene glycol aqueous solutions, and the concentration of the ethylene glycol aqueous solutions is 20-60%. The temperature of the glycol water solution is increased by absorbing heat, and the glycol water solution is more beneficial to the operation of equipment and has better heat exchange efficiency compared with water used as a circulating medium.
As shown in fig. 1, a water outlet of the first coil 7 is connected to a water inlet of a water source heat pump 20 through a fifth pipeline 5-5, a water outlet of the water source heat pump 20 is connected to a water inlet of the first coil 7 through a sixth pipeline 5-6, the water source heat pump 20 is connected to a heat consumer 11, a water inlet of a second coil 8 disposed below the first coil 7 is connected to a water outlet of a solar heat collecting plate 1 through a first pipeline 5-1, and a water inlet of the solar heat collecting plate 1 is connected to a water outlet of the second coil 8 through a second pipeline 5-2. Therefore, under the condition of sufficient sunlight in the daytime, the solar heat collecting plate 1 absorbs heat and releases heat through the first pipeline 5-1 and the second coil 8 to increase the temperature of water in the pool, and the temperature of the circulating medium after heat release is reduced and flows back to the solar heat collecting plate 1 through the second pipeline 5-2 to continuously absorb heat; the ice near the heat release of the second coil 8 slowly melts and the water temperature rises and floats upwards to the vicinity of the first coil 7, the heat absorption temperature of the circulating medium in the first coil 7 rises, the circulating medium flows back to the water source heat pump 20 through the fifth pipeline 5-5 to release heat for heating a heat user 11, and the temperature of the circulating medium after heat release decreases and flows back to the first coil 7 through the sixth pipeline 5-6 to continuously absorb heat. The whole heating process is clean and environment-friendly, no pollutant is discharged, and the ethylene glycol circulating medium is arranged in the solar heat collecting plate 1, so that the damage caused by the icing of the solar heat collecting plate 1 can be effectively prevented.
Solar energy is greatly influenced by day and night, if the system is used for heating normally under the condition that solar energy exists in the day, and the heat generated by changing water in the water pool 6 into ice at night supplies heat for users, so that the requirement of a heat user 11 is met. In order to ensure the normal operation of the system, a third pipeline 5-3, a fourth pipeline 5-4 and an intelligent control unit are additionally arranged. The operation thereof will be described in detail below.

The controller 21 is a PLC control unit, a single chip microcomputer or other products with intelligent control function.
When the temperature of the heat energy absorbed by the solar heat collecting plate 1 is increased, the first temperature sensor 2 transmits the measured temperature information to the input end of the controller 21 in real time, after the controller 21 analyzes, compares and judges, when the temperature of the first temperature sensor 2 reaches a set value, the controller 21 sends an opening command to the first electric control valve 3, the second electric control valve 12, the third electric control valve 17, the fourth electric control valve 18 and the circulating pump 13 which are connected with the output end, and the daytime heating mode is started. The circulating pump 13 can timely convey the circulating medium which is subjected to heat release in the second coil 8 into the solar heat collecting plate 1.
As shown in fig. 1, check valves 19 are disposed on the fifth pipeline 5-5 and the sixth pipeline 5-6, and the check valves 19 can effectively prevent water from flowing backwards.

As shown in fig. 1 and fig. 2, a second temperature sensor 16 is disposed at the water outlet of the water source heat pump 20, and the second temperature sensor 16 is electrically connected to an input end of a controller 21. At night, after the second coil pipe 8 absorbs the waste heat of the water in the water tank 6 to heat the user 11 for a period of time, when the temperature value measured by the second temperature sensor 16 is lower than the set value, the controller 21 sends a command to the output end to open the third electric control valve 17 and the fourth electric control valve 18, and at this moment, the first coil pipe 7 and the second coil pipe 8 absorb the heat released by the water in the water tank together to heat the user 11. When the heat released by the liquid water is changed into the liquid water at 0 ℃, part of the heat released by the liquid water is continuously condensed into the solid ice to form an ice-water mixture at 0 ℃, the water is changed from the liquid state into the solid state to release the heat, the heat is supplied to the hot users 11 by the water supply source heat pump 20, the temperature of the glycol water solution is increased when the concentration of the glycol water solution is 20-60%, and the temperature of the heat released by the condensation of the water into the ice is increased by the glycol water solution in the first coil 7 and the second coil 8, so that the hot users 11 can be heated at night.
Through experiment, the sun is sufficient daytime, freezes less in the pond 6 night, and when the sunlight was insufficient daytime, it can be more to freeze night, but 90% water freezes the heat of releasing in the at utmost pond 6 can satisfy the hot user 11 heating needs at night, and the water of the same volume becomes the water that ice releases and becomes the heat that 0 degree released equivalent to 80 degrees, proves through the experiment: the heat released by the freezing of water in the water pool 6 is sufficient to meet the heating needs of the user 11 at night. In cold winter, the pool 6 is preferably arranged indoors due to large temperature difference between the indoor and the outdoor, which is more beneficial to heat exchange.
To sum up, the system utilizes solar energy to heat at daytime and utilizes heat released by water phase change at night to heat, so that the requirement of a heat user 11 on continuous heating day and night is met, the intermittent and unstable conditions of heating by solar energy alone are avoided, and the system is energy-saving, environment-friendly, low in operation and maintenance cost, compact in structure, high in energy utilization rate and necessary for popularization.
