Description

Technical Field

[0001] The invention relates to the field of heating and heat supply, and in particular to the field of a freezing-proof solar water heater heating control device. Background Art

[0002] At present, indoor heating mostly adopts centralized heating, wall-mounted boiler heating and air energy. The former has the disadvantages of high laying cost and the latter two have high purchase cost. As the country vigorously advocates the implementation of energy conservation and emission reduction, environmental protection and economic measures, and the requirements for energy conservation and environmental protection are increasing, solar water heater heating has practical problems:

[0003] 1. It is limited to hot water used in the kitchen and bathing, and does not provide constant temperature heating for indoor use, and fails to give full play to the heating function of solar water heaters.

[0004] 2. Due to the existing technology, solar heating devices are often damaged by freezing. Severe freezing damage affects the normal use of heating, and it is difficult to keep the indoor temperature constant to a comfortable living temperature in winter. Summary of the invention

[0005] The purpose of the present invention is to provide an antifreeze type solar water heater heating control device, which is characterized in that it includes: a solar water heater, a primary circulation system, a relay insulation barrel, a secondary circulation system, a heat dissipation device, a liquid storage tank, a circulation pump, a tap water pipe, a domestic hot water pipe, a control device, and a heat transfer liquid. The solar water heater insulation barrel has a built-in heat exchanger to provide a heat source. The solar water heater contains heat transfer liquid and the built-in exchanger contains tap water. The primary circulation system is a heat circulation system between the solar water heater and the relay insulation barrel, which transfers the heat of the solar energy to the relay insulation barrel through a circulation pump and heat transfer liquid for storage. The relay insulation barrel has a function of storing and heat-insulating the exchanged heat of the solar water heater. The relay insulation barrel has a built-in heat exchanger to provide a heat source for the heat dissipation device. The secondary circulation system is a heat circulation system between the relay insulation barrel and the heat dissipation device, which transfers the heat in the relay insulation barrel to the heat dissipation device through a circulation pump and heat transfer liquid. The heat dissipation device performs heat exchange with the room. The liquid storage tank is a heat exchange tank for storing heat transfer liquid and can also serve as an auxiliary heat device. The auxiliary heat tank is used for heating when there is no sunlight for many days. The circulation pump plays a role in maintaining the normal circulation of the heat transfer liquid in the system. The tap water pipe is a pipe-in-pipe structure of the primary circulation system. The outdoor part is a sleeve-type structure with a pipe in a pipe. The pipe for providing domestic hot water is provided through the internal heat exchanger of the solar water heater and the internal heat exchanger of the relay barrel. When there is no heating in summer, the stop valve can be opened to directly provide domestic hot water without passing through the heat exchanger in the relay barrel. The domestic hot water pipe provides hot water pipes for kitchens and bathrooms. The control device is an electronic device, including at least one memory and at least one processor; the memory stores executable instructions of the processor; the processor is configured to execute the above method, control the start and stop of the circulation system, make the system work normally, and ensure that the room temperature is constant at a comfortable temperature; the heat transfer liquid is antifreeze and / or heat transfer oil suitable for different regions.

[0006] The present invention realizes a freezing-proof solar water heater heating control device, which has the following advantages:

[0007] 1. The indoor constant temperature device of solar water heater heating can achieve constant indoor temperature to a livable temperature in winter, and the use of water in the relay barrel greatly saves the cost of use;

[0008] 2. Set the working parameter value of the control device to automatically control and achieve the required constant heating temperature;

[0009] 3. Heat exchange is carried out through the heat exchanger in the solar insulation barrel and the heat transfer liquid in the relay insulation barrel, which neither affects the use of hot water in the kitchen and bathroom nor the normal use of the heating system; the use of antifreeze greatly reduces the freezing loss of the heating system and improves the comfort of heating.

[0010] 4. Using an antifreeze solar water heater to heat the room with a constant temperature device can achieve high efficiency, energy saving, low carbon, environmental protection, clean and economical use effects. BRIEF DESCRIPTION OF THE DRAWINGS

The top heat exchanger (11) in the relay insulation barrel is connected to the water distributor (15) through a pipeline and then connected to the indoor heat dissipation device (17), and is connected to the liquid storage tank (14) through the water distributor (16). The liquid storage tank (14) is connected to the circulation pump (12), and the circulation pump (12) is connected to the top heat exchanger (11) in the relay insulation barrel, forming a closed loop of the indoor heat circulation system of the heat transfer liquid, that is, a secondary circulation system.

[0017] Reference Manual Attached Figure 2 As shown, the control device (19) is connected to the probe (20), the probe (21), the probe (22), the probe (23), the circulation pumps (6) and (12).

[0018] As a specific example, please refer to Figure 1As shown, the solar water heater insulation barrel (1) is connected to the bottom heat exchanger (13) in the relay insulation barrel through the upper liquid outer tube (2), the lower liquid outer tube (3) and the circulation pump (6), and plays the role of heat exchange with the relay insulation barrel. The circulation pump (6) plays the role of maintaining the normal circulation of the heat transfer liquid, so that the heat in the solar insulation barrel is transferred to the relay insulation barrel through the primary circulation system and stored. The top heat exchanger (11) in the relay insulation barrel is connected to the heat dissipation device (17) through the water distributor (15), and then connected to the liquid storage tank (14) through the water distributor (16). The liquid storage tank (14) plays the role of storing the heat transfer liquid; the liquid storage tank (14) is connected to the circulation pump (12), and the circulation pump (12) plays the role of maintaining the normal circulation of the heat transfer liquid. The circulation pump (12) is connected to the top heat exchanger (11) in the relay insulation barrel to maintain the normal circulation of the heat transfer liquid in the closed loop of the heat cycle, so that the heat in the relay insulation barrel is transferred to the heat dissipation device (17) through the secondary circulation system, and the heat dissipation device (17) exchanges heat with the indoor cold air.

[0019] As a specific example, please refer to Figure 2 As shown, when the water temperature probe (20) of the solar water heater on the control device (19) detects that the water temperature of the solar water heater is greater than the bottom temperature of the relay insulation barrel measured by the bottom temperature probe (21) in the relay insulation barrel, the control device (19) sends a command to the circulation pump (6), the circulation pump (6) is powered on and started, and the primary circulation system operates, so that the heat of the solar insulation barrel and the heat of the relay insulation barrel are heat exchanged. When the bottom temperature in the relay insulation barrel reaches the water temperature of the solar water heater, the control device (19) stops sending commands, the circulation pump (6) is powered off and stops running after there is no command, and the heat transfer liquid in the closed loop of the primary circulation system stops running. When the indoor temperature probe (23) on the control device (19) measures that the indoor temperature is lower than the set value of the indoor temperature and the indoor temperature is lower than the top temperature of the relay insulation barrel measured by the top temperature probe (22) in the relay insulation barrel, the control device (19) sends a command to the circulation pump (12), the circulation pump (12) is powered on and started, and the secondary circulation system operates, so that the heat of the relay insulation barrel exchanges heat with the heat exchange device (17). When the indoor temperature probe (23) on the control device (19) measures that the indoor temperature is higher than the set value of the indoor temperature, the control device (19) stops sending commands, the circulation pump (12) is powered off and stops operating after there is no command, and the heat transfer liquid in the closed loop of the secondary circulation system stops running.

[0020] Through the alternating cycle of normal heating and stopping heating, the indoor temperature gradually reaches the set indoor temperature value and finally becomes constant within the set temperature range, achieving the purpose of indoor constant temperature and energy saving.

[0021] The size of the solar water heater insulation storage tank and relay insulation barrel should be higher than the average winter temperature in the region and selected in combination with the required heat parameters of the most unfavorable factors, and the specifications and quantity of the heat collecting tubes should be matched to meet the winter heating needs. The heat transfer liquid of the primary circulation system and the secondary circulation system is preferably antifreeze that matches the regional temperature, followed by heat transfer oil that matches the regional temperature. In areas above freezing point, water can be used for heat transfer and the corresponding heat exchangers and storage tanks can be reduced to save costs.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
