Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a system block diagram of an air-energy water heating apparatus according to the present invention is shown. The air energy water heating device 10 heats a water resource at normal temperature by adopting an air energy heating mode to provide hot water at a set temperature. The air-energy water heating device 10 comprises an inlet 11, a heat exchange module 13, a heat energy providing module 15, an energy storage 16, an evaporation module 17, a buffer tank 18 and an outlet 19. The inlet 11, the heat exchange module 13, the buffer tank 18 and the outlet 19 of the air energy water heating device 10 are connected in sequence to form a water circulation branch. In the water circulation branch, low-temperature water resources are heated to obtain high-temperature water for use. The heat energy providing module 15, the energy storage 16, the heat exchange module 13 and the evaporation module 17 of the air energy water heating device 10 are sequentially connected to form an air circulation branch. In the air circulation branch, the high-temperature air forms low-temperature air after circulating through the branch and is discharged to the surrounding environment.

The air-energy water heating device 10 is connected to an external water supply device (not shown) through a pipe, and the external water supply device supplies normal-temperature water or low-temperature water to the air-energy water heating device 10 through the inlet 11. Specifically, the external water resource supply device may be a drinking water supply device such as a tap. The normal-temperature water or the low-temperature water refers to water resources which need to be further heated to meet other purposes of drinking or cooling, such as: water from a faucet at a temperature between 25 degrees celsius and 30 degrees celsius is considered normal temperature water.

The heat exchange module 13 receives low temperature water from the inlet 11 and high temperature air from the energy storage tank 18. In the heat exchange module 13, the low-temperature water and the high-temperature air exchange heat with each other, so that heat energy transfer is realized. Specifically, the low-temperature water is subjected to heat energy exchange by the heat exchange module 13, and absorbs heat energy from the high-energy air to generate high-temperature water; on the other hand, the high-energy air is subjected to heat exchange by the heat exchange module 13, and the energy is released and transferred to the low-temperature water to generate low-temperature air.

The heat energy providing module 15 is an air compressor, which compresses low-pressure normal-temperature gas to apply work to obtain high-energy air, and stores the high-energy air in the energy storage device 16.

Two ends of the energy accumulator 16 are respectively connected with the thermal energy providing device 15 and the heat exchange module 13 through pipelines. The energy storage device 16 comprises a pressure sensor 160, which receives the high-energy air provided by the thermal energy providing module 15, so as to further increase the air pressure inside the energy storage tank 16, wherein the pressure sensor 160 correspondingly provides the high-energy air to sequentially pass through the thermal energy providing module 15, the energy storage tank 16 and the heat exchange module 13 based on the pressure difference between the energy storage tank 16 and the heat exchange module 13.

Further, when the pressure sensor 160 senses that the pressure value of the energy storage 16 is equal to a set value, the thermal energy providing module 15 stops providing the high-energy gas to the energy storage 16, so that the energy storage 16 always maintains the air energy with the constant pressure.

The evaporator module 17 is a fan set that receives the low temperature air from the heat exchanger module 13 and discharges it to the ambient environment. That is, the low-temperature air inside the heat exchange module 13 is circulated to the air in the ambient environment by the evaporation module 17, and heat exchange between the low-temperature air inside the heat exchange module 13 and the high-temperature gas in the external environment is realized.

To this end, the heat energy providing module 15, the energy storage 16, the heat exchange module 13 and the evaporation module 17 of the air-energy hydrothermal device 10 are sequentially connected to realize continuous circulation of air, and in the circulation process, the air realizes heat exchange twice, wherein the first time is that high-energy air transfers heat energy to low-temperature water in the heat exchange module 13, and the second time is that heat exchange between low-temperature air and the environment is performed, and cold air is discharged to the surrounding environment.

One end of the buffer tank 18 is connected with the heat exchange module 13, and the other end is directly connected with the outlet 19. The cache tank 18 stores the high-temperature water heated by the heat exchange module 13 for use. The buffer tank 18 comprises a temperature sensor 180 and a circulating water pump 181. The temperature sensor 180 senses a temperature value of the hot water in the cache tank 18 in real time, and drives the circulating water pump 181 to adjust a working state thereof based on the sensed temperature value corresponding to the feedback control signal. When the temperature sensor 180 senses that the temperature of hot water in the cache tank 18 is lower than a set value, the circulating water pump 181 is started to drive the water in the cache tank 18 to circulate to the heat exchange module 13 again for circulating heating, so as to further improve the water temperature; when the temperature sensor 180 senses that the temperature of the hot water in the buffer tank 18 is equal to a set value, the circulating water pump 181 stops pumping water, so that the water in the buffer tank 18 is stored at a constant temperature.

To this end, the inlet 11, the heat exchange module 13, the buffer tank 18 and the outlet 19 of the air-energy water heating device 10 are sequentially connected to realize continuous circulation of water, wherein the buffer tank 18 is bidirectionally connected with the heat exchange module 13. Flowing from the heat exchange module 13 to the buffer tank 18, and flowing the high-temperature water heated by the heat exchange module 13 to the buffer tank 18 for storage; and the water which flows from the cache tank 18 to the heat exchange module 13 and is lower than the set temperature circulates to the heat exchange module 13 again to realize reheating, and the temperature of the increased water meets the set value.

In the circulation process, the low-temperature water passes through the heat exchange module 13 to obtain heat energy to increase the water temperature to generate high-temperature water, and the high-temperature water is stored in the cache tank 18, when the water temperature in the cache tank 18 is lower than a set value, the circulating water pump 181 is correspondingly started to enable the cache tank 18 and the heat exchange module 13 to circulate again, so that the water is reheated, and the water temperature in the cache tank 18 is ensured to reach the set value.

Referring to fig. 2, a flow chart of a control method of the air-energy water heating device shown in fig. 1 is shown. When the air-to-water heating apparatus 10 is in operation, it includes the steps of:

step S01, providing low-temperature water from the inlet 11 to the heat exchange module 13;

step S02, the heat energy providing module 15 compresses atmospheric air to obtain high energy air, and the high energy air is provided to the heat exchange module 13 through the energy storage device 16;

step S03, in the heat exchange module 13, the low-temperature water and the high-energy air are heat exchanged to generate high-temperature water and low-temperature air respectively;

step S04, providing a buffer tank 18 to receive the high-temperature water heated by the heat exchange module 13 and store the high-temperature water in the buffer tank 18;

step S05, the evaporation module 17 is provided to receive the low temperature air passing through the heat exchange module 13 and discharge the low temperature air to the environment.

In the working process of the air-energy water heating device 10, the heat energy providing module 15, the energy storage 16, the heat exchange module 13 and the evaporation module 17 are sequentially connected to form an air circulation branch, so that circulation of air from high temperature to low temperature is realized; meanwhile, the inlet 11, the heat exchange module 13, the buffer tank 18 and the outlet 19 are sequentially connected to form a water circulation branch, so that circulation from low-temperature water to high-temperature water is realized.

In the method for controlling heating of water by the air-source water heating apparatus 10, the step S01 and the step S02 may be performed simultaneously, and the step S04 and the step S05 may be performed simultaneously, without any order.

In step S02, a pressure sensor 160 is disposed in the energy storage 16, and when it is sensed that the pressure value in the energy storage 16 is lower than a set value, the thermal energy providing module 15 correspondingly pumps high-energy air into the energy storage 16, otherwise, the thermal energy providing module 15 stops working. In this step, the energy storage 16 is used as a high-energy air buffer device disposed between the thermal energy providing module 15 and the heat exchange module 13, and it ensures that the high-energy air provided to the thermal energy exchange module 13 is always provided in a constant-pressure steady-state manner, and is not limited by unstable factors caused by the limitation of the working conditions of the compressor such as power, so as to greatly reduce power consumption, and at the same time, ensures that the high-energy air in the thermal energy exchange module 13 continuously and stably provides thermal energy.

In step S04, a buffer tank 18 is additionally installed between the heat exchange module 13 and the outlet 19 to store the high-temperature water with the water temperature up to a predetermined value for standby. Meanwhile, the buffer tank 18 and the heat exchange module 13 are circulated in two directions, and when the temperature of water in the buffer tank 18 is lower than a set value, the water is circulated again from the buffer tank 18 to the heat exchange module 13 through the circulating water pump 181, and then is heated again.

Compared with the prior art, in the air energy water heating device 10 of the present invention, the energy storage 16 and the buffer tank 18 are respectively added in the air energy circulation branch and the water circulation branch, so as to respectively control the high energy air entering the heat exchange module 13 to have a constant pressure and the high temperature water flowing out from the outlet to reach a set temperature value, further reduce power consumption, and perform intelligent control.

The above description is only a part of the embodiments of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present invention as described in the specification and the accompanying drawings, or applied directly or indirectly to other related technical fields, are included in the scope of the present invention.
