[ EXAMPLES one ]
As shown in fig. 1, an aquaculture facility includes a facility body 10, and a culture pond 30 provided in the facility body 10, wherein the facility body 10 includes a glass greenhouse, a vinyl house, and the like.
Further, a heat pump system 100, a circulation pump 60, and a heating coil 40 are provided in the facility body 10. Wherein the heat pump system 100 is installed inside the facility body 10 outside the aquaculture pond 30. The heat pump system 100 is directly in contact with the air in the facility body 10, and transfers the heat energy in the air to the water body by using the heat energy generated by the greenhouse effect of the facility. Specifically, the heat pump system 100 includes a heat pump unit 20.
Further, the heat pump system 100 is connected to the heat supply coil 40 through a water pipe 90, and the heat supply coil 40 is installed at the bottom of the culture pond 30, and the bottom of the culture pond 30 includes: in the culture pond 30 or in the soil below the culture pond 30. The circulation pump 60 is water-linked to the heat pump system 100 through a water pipe 90 at one end and to the heating coil 40 at the other end. The circulation pump 60 is used to press the hot water heat-exchanged by the heat pump system 100 into the heating coil 40 by water pressure. After the hot water flows for one circle in the heat supply coil pipe 40, the heat is absorbed by the water body in the culture pond 30, the water temperature in the pipeline is reduced, and the hot water enters the heat pump unit 20 again for heat exchange, so that circulation is realized, the heat is continuously conveyed to the culture pond 30, and the effects of stable heat supply and no pollution are achieved.
Further, the heat pump system 100 is provided with a temperature sensor and a controller, the temperature sensor is electrically connected with the controller, and the controller is electrically connected with the heat pump unit 20 and the circulation pump 60. The electrical connection fingers may be directly connected by wires or may be connected by a wireless signal transmitter/receiver such as bluetooth. The temperature sensor is used for detecting the air temperature in the facility body 10 and transmitting a temperature signal to the controller, and the controller controls the working states of the heat pump unit 20 and the circulating pump 60 according to the relative magnitude of the temperature signal and the preset temperature.
In practical application, the preset temperature can be selected according to regional climate and habit of fish. When the temperature in the facility body 10 is greater than or equal to the preset temperature, the controller starts the heat pump unit 20 and the circulating pump 60; at this time, sufficient heat is provided in the facility body 10 to heat the heat pump unit 20, and the heat of the air in the facility body 10 is transferred to the culture pond 30. When the temperature in the facility body 10 is lower than the preset temperature, the controller turns off the heat pump unit 20 and the circulation pump 60. At this time, the heat of the air in the facility body 10 is not enough to provide the heat pump unit 20 for heat exchange, and the heat pump unit 20 and the circulation pump 60 are turned off to avoid unnecessary energy waste. In addition, when the temperature is low, the efficiency of the heat pump unit 20 is reduced, the heat pump unit 20 is turned off, and the power consumption is reduced. Meanwhile, the heat stored at the bottom of the culture pond 30 is transferred to the water body of the culture pond 30, and the temperature of the water body is ensured.
[ example two ]
This embodiment is an aquaculture facility, as shown in fig. 1, which includes all the technical features of the first embodiment, and similar parts are not repeated herein.
Further preferably, the heat pump unit 20 includes a water inlet and a water outlet, the water outlet is connected in parallel with the plurality of sets of heating coils 40 through the water collecting and distributing device 50, and the heating coils 40 are finally connected to the water inlet to form a hot water circulating system. In other words, the aquaculture facility is provided with a plurality of groups of heat supply coils 40, the synchronous connection of the plurality of groups of heat supply coils 40 is realized through the water dividing and collecting device 50, and hot water discharged from the water outlet of the heat pump unit 20 can simultaneously enter the plurality of groups of heat supply coils 40, so that on one hand, the hot water simultaneously enters the plurality of groups of heat supply coils 40, and the water temperature is uniformly heated by utilizing the same-process water supply principle; on the other hand, the problem that the temperature difference between the first section and the tail end of the heating coil 40 is large due to the fact that the heating coil 40 is too long is solved.
In a preferred embodiment, the aquaculture facility further comprises a water supply tank 70 and a heat preservation structure, wherein the water supply tank 70 is connected with the heat pump unit 20 through a water pipe 90, and preferably, the water supply tank 70 is an expansion water tank provided with a water supply system interface. It should be noted that the water supply system 80 may be a tap water system or a common water source, and is aimed at supplying clean water to the hot water circulation system in time due to the change of water volume caused by temperature change in the hot water circulation system. The water supply tank 70 or the expansion tank is designed to supply water pressure to the inside of the hot water circulation system, thereby preventing air bubbles from being generated according to the volume change of water in the water pipe 90. The heat insulation structure is installed on the surface of the facility body 10, is located on the top and the side of the facility body 10, and is matched with the facility body 10 to form a closed space. Preferably, the heat-insulating structure comprises a heat-insulating curtain, and the heat-insulating curtain is a light nano-scale heat-insulating quilt or other heat-insulating curtains, such as a plastic curtain; wherein, the heat preservation curtain positioned at the top of the facility main body 10 can be controlled to be folded or unfolded through a gear rack transmission system; the thermal insulation curtain on the side wall of the facility main body 10 can be controlled to be folded or unfolded through a curtain rolling device. The material of the heating coil 40 is any one of PE, PE-RT, PPR and PE-X, or other materials in the prior art.
In practical applications, the ambient temperature is different due to the different light intensities during the day and at night. When the sunlight reaches a certain intensity, the heat-preservation curtain is folded manually or by a heat-preservation curtain control device to supplement the internal temperature of the facility main body 10; when the sunlight is lower than a certain intensity, the heat-insulating curtain is unfolded manually or by a heat-insulating curtain control device to block the internal temperature loss of the facility main body 10. When the outside temperature is lower, the heat preservation curtain delays the folding time; when the outside temperature is higher, the heat preservation curtain is unfolded for a time in advance. On one hand, whether the heat preservation curtain is folded or not can be judged according to the light intensity, and the room temperature of the facility main body 10 is supplemented; on the other hand, whether the folding heat preservation curtain can cause the room temperature of the facility main body 10 to be lost or not can be judged by detecting the external temperature, so that the facility can adapt to climates of different seasons and regions.
It should be noted that the difference between aquaculture and planting is that the maximum light input quantity of planting facilities is required as far as possible, and aquaculture is not required, so that the heat preservation curtain is covered as far as possible in a delayed and early manner when the temperature is low in the morning and evening. In addition, the water temperature required by aquaculture is higher and is required to be 25-32 ℃, the air temperature has little influence on aquaculture, and high temperature in the facility can be utilized to improve the efficiency of the heat pump unit 20 (when the temperature of the planting shed exceeds 28 ℃, ventilation is needed, so that the unit is difficult to utilize higher temperature in the facility). Therefore, how to utilize the requirement of aquaculture on solar rays, reduce the loss of the facility main body 10 at room temperature and increase the conversion efficiency of the heat pump unit 20 has certain innovation in the technical field.
In the actual manufacturing process, in order to increase the heating area of the water body of the culture pond 30, the heat supply coil pipes 40 are S-shaped, double rows are horizontally laid at the bottom of the culture pond 30, the diameter of each heat supply coil pipe 40 is 20-50mm, and the arrangement distance of different heat supply coil pipes 40 is 400-800 mm. In order to further increase the stability and durability of the system heat supply, the heat supply coil 40 can be buried in the soil at the bottom of the culture pond 30 and is 600mm away from the bottom of the culture pond 30.
In addition, as shown in fig. 2, an automatic exhaust valve 91 may be disposed at the water outlet of the heat pump unit 20, and the automatic exhaust valve 91 is installed on the water pipe 90 to discharge air at any time when air is present in the hot water circulation system, so as to supplement water in time through the water supplement tank 70. And different heating coils 40 are simultaneously connected with the heat pump unit 20 through the water dividing and collecting device 50. As shown in fig. 3, a ball valve 51 is disposed at an interface of the water distributor and collector 50, and can be used to close a connection water pipe 90 between the water distributor and collector 50 and the heat pump unit 20, so as to prevent the heat supply coil 40 from leaking.
[ EXAMPLE III ]
The present embodiment is a water body heating and heat storage method for an aquaculture facility, and the aquaculture facility is the same as the aquaculture facility in the above embodiments, and is not described herein again.
Further preferably, when the sunlight reaches a certain intensity in the daytime, the heat preservation curtain is folded to supplement the internal temperature of the facility main body 10; when the sunlight is lower than a certain intensity in the daytime, the heat preservation curtain is unfolded to block the internal temperature loss of the facility main body 10; when the outside temperature of the facility main body 10 is low in the daytime, the heat preservation curtain delays the folding time; when the outside temperature of the facility main body 10 is high in the daytime, the heat preservation curtain is unfolded for a time in advance.
Further preferably, in summer or in high-temperature seasons, when the temperature of the water body in the culture pond 30 approaches the upper limit of the suitable culture temperature, the temperature in the facility and the temperature of the water body can be reduced through measures such as ventilation and shading of the greenhouse, and the temperature of the water body can also be reduced through refrigeration of the heat pump.
In practical application, when the sunlight and the outside temperature of the facility main body 10 both satisfy a certain range, the heat-insulating curtain can be folded, and at the moment, the sunlight is sufficient, the outside temperature is high, and the air temperature in the facility main body 10 can be rapidly raised. When the air temperature in the facility main body 10 rises to the preset temperature, the controller starts the heat pump unit 20 and the circulating pump 60, the heat pump unit 20 performs heat exchange, and the heat of the air in the facility main body 10 is transferred to the aquaculture pond 30. When the solar ray and the outside temperature of the facility main body 10 are both at a lower level, the heat preservation curtain is in an unfolded state, so that the heat loss of the air in the facility main body 10 is reduced to the maximum extent.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
