Background
As is well known, in the breeding industry, maintaining an environment temperature suitable for a breeding house is a key factor for success of poultry breeding; especially in summer, winter and early spring, it is more important to control the environmental temperature of the breeding house.
Generally speaking, the ideal temperature of poultry such as chicken and duck is 30-33 ℃ in brooding period and 20-25 ℃ in brooding period. Therefore, in general, the heat preservation in brooding period is to prevent the invasion of harmful wind and intercalary wind. The chicks are ensured to be evenly distributed, have normal appetite, are quiet and can move freely, and the problem of pricking and heating caused by frostbite is avoided. Similarly, in early spring or winter, the breeding density is high, the people should pay attention to cold prevention and warm keeping, ventilation and air exchange are needed, and if the people do not frequently ventilate and exchange air, the air in the house is easily polluted, germs grow and diseases are caused. However, the temperature of the breeding house needs to be reasonably lowered frequently in summer, poultry infection germs caused by overheating of the temperature are avoided, and the problem that feeding is reduced after overheating to influence growth is avoided.
In this regard, the conventional breeding houses often adopt the following technical means to control the ambient temperature for the above situations:
in winter, the traditional breeding house can be heated by heating equipment, but if a large amount of heating equipment is adopted, the energy consumption is greatly increased, the breeding cost is increased, and meanwhile, the energy waste is also caused.
Meanwhile, in summer, a large amount of refrigeration equipment is also needed to be installed in the traditional breeding house to reasonably cool the temperature of the breeding house, so that the normal growth temperature of poultry in the house is ensured; this would result in the reinstallation of a new refrigeration plant, which, however, would further increase the cost of the farming.
In summary, a technical problem to be solved by the technicians in the field needs to be solved urgently how to design an energy-saving and environment-friendly cultivation equipment device integrating multiple functions of comprehensive central heating, refrigeration, air exchange and the like.

The underground pipe ventilation system, the fresh air heat exchange system and the indoor heat exchange system are basically in normally open states; in extremely cold weather in winter, in case that the fresh air temperature provided by the buried pipe ventilation system is too low, the fresh air unit is damaged or cannot work normally, the ground source heat pump auxiliary heating system needs to be started; in general, in non-arctic weather, the ground source heat pump auxiliary heating system does not need to be started.

The outside new trend of breed house gets into the flow direction as follows among the buried pipe ventilation system: fresh air firstly enters from a first fresh air inlet pipe, then enters into a first buried pipe, and finally flows into a fresh air unit from a first fresh air outlet pipe. In the first buried pipe, the fresh air exchanges temperature with the surrounding strata of the first buried pipe buried in the strata below the surface of the earth. Generally, in summer hot weather, the temperature of the stratum below the ground surface is lower than that of the air, so that the temperature of fresh air in the first buried pipe is reduced; in cold weather in winter, the temperature of the stratum below the earth surface is higher than that of the air, so that the temperature of the fresh air in the first buried pipe can be raised.
In extremely cold weather in winter, the flow direction that the outside new trend of breed house gets into in the supplementary heating system of ground source heat pump is as follows: fresh air firstly enters from a second fresh air inlet pipe, then enters into a second buried pipe, and finally flows into the fresh air unit from a second fresh air outlet pipe. Because of the second buried pipe buries in the stratum of being dark in first buried pipe position underground, so, the temperature in second buried pipe place stratum will be higher than the temperature in first buried pipe place stratum, so the temperature rise value of new trend in the second buried pipe will be higher than the temperature rise value in first buried pipe, the new trend temperature that flows out by second new trend play tuber pipe promptly will be higher than the new trend temperature that flows out of first new trend play tuber pipe, both coacts and is used for making the new trend temperature that flows in the new fan unit can guarantee the normal operating of new fan unit.
In the indoor heat exchange system of the breeding house, air in the breeding house enters the air exhaust pipe through an air exhaust port on the air exhaust pipe, and then enters the fresh air unit through air in the breeding house entering the air exhaust pipe; under the action of the fresh air handling unit, the air in the house can exchange heat with fresh air flowing into the fresh air handling unit from a first fresh air outlet pipe in the buried pipe ventilation system; thus, the temperature of the fresh air can be changed again to be closer to the indoor adjusted comfortable temperature (warm in winter and cool in summer).
The temperature of the fresh air which is subjected to temperature pre-adjustment in the fresh air handling unit can be adjusted again under the action of the air cooling module, and the energy consumption of the air cooling module can be saved due to the fact that the fresh air is subjected to temperature pre-adjustment; then, the fresh air adjusted in temperature by the fresh air unit enters an air inlet pipe in the indoor heat exchange system and finally enters the room through an air inlet on the air inlet pipe, so that the indoor temperature is always in a comfortable state.

the depth of the second buried pipe 430 is deeper than the depth of the first buried pipe 130.
Correspondingly, referring to fig. 7, the invention also provides a breeding house, which comprises a breeding house body and the environment-friendly temperature-supplying and ventilating heat exchange device for the breeding house, wherein the environment-friendly temperature-supplying and ventilating heat exchange device for the breeding house is used for realizing ventilation and temperature-adjusting operations on the breeding house body.
In the system, the buried pipe ventilation system 100, the fresh air heat exchange system 200 and the indoor heat exchange system 300 are basically in a normally open state; in the extremely cold weather in winter, in case that the fresh air temperature provided by the buried pipe ventilation system 100 is too low, and the fresh air unit 220 is damaged or cannot normally work, the ground source heat pump auxiliary heating system 400 needs to be started; in general, in non-arctic weather, the ground source heat pump auxiliary heating system 400 does not need to be started. The four systems are directly or indirectly connected with each other to jointly complete the tasks of ventilating the breeding house and adjusting the temperature in the breeding house, and the underground pipe ventilation system 100 and the ground source heat pump auxiliary heating system 400 can also achieve the purpose of energy conservation.

In extremely cold weather in winter, the flow direction of fresh air outside the breeding house entering the ground source heat pump auxiliary heating system 400 is as follows: fresh air firstly enters the second fresh air inlet pipe 410, then enters the second buried pipe 430, and finally flows into the fresh air unit 220 through the second fresh air outlet pipe 420. Because the second buried pipe 430 is buried in the stratum deeper than the first buried pipe 130, the temperature of the stratum where the second buried pipe 430 is located is higher than the temperature of the stratum where the first buried pipe 130 is located, so the temperature of the fresh air in the second buried pipe 430 is higher than the temperature of the fresh air in the first buried pipe 130, that is, the temperature of the fresh air flowing out from the second fresh air outlet pipe 420 is higher than the temperature of the fresh air flowing out from the first fresh air outlet pipe 120, and the two pipes work together to ensure that the temperature of the fresh air flowing into the fresh air handling unit 220 can ensure the normal operation of the fresh air handling unit 220.
In the indoor heat exchange system 300 of the breeding house, the air inside the breeding house enters the exhaust duct 320 through the exhaust port 321 on the exhaust duct 320, and then enters the fresh air unit 220 through the air inside the breeding house entering the exhaust duct 320; under the action of the fresh air handling unit 220, the air in the house exchanges heat with the fresh air flowing into the fresh air handling unit 220 from the first fresh air outlet pipe 120 in the buried pipe ventilation system 100; thus, the temperature of the fresh air can be changed again to be closer to the indoor adjusted comfortable temperature (warm in winter and cool in summer).
The temperature of the fresh air which is subjected to the temperature pre-adjustment in the fresh air handling unit 220 can be adjusted again under the action of the air cooling module 210, and the energy consumption of the air cooling module 210 can be saved due to the fact that the fresh air is subjected to the temperature pre-adjustment treatment; then, the fresh air adjusted in temperature by the fresh air unit 220 enters the air inlet pipe 310 of the indoor heat exchange system 300, and finally enters the room through the air inlet 311 of the air inlet pipe 310, so that the indoor temperature is always in a comfortable state.
In conclusion, the environment-friendly heating and ventilating heat exchange system and the breeding house provided by the invention integrate multiple functions of central heating, refrigeration, air exchange and the like, are energy-saving and environment-friendly, and have novel and stable system structure.

The first buried pipe 130 is arranged into two layers, so that the occupied area is reduced on the basis of ensuring the contact area of fresh air and a mud layer, and a pit for burying the first buried pipe 130 is dug a little more to the deep part; and the difference between the two layers is 1 meter, so that the heat exchange effect between the fresh air in the first buried pipe 130 and the surrounding soil layer can not be influenced completely. The depth of the first buried pipe 130 may withstand the weather of a temperature higher than-15 deg.
In addition, the areas of the planes occupied by the first upper buried pipe and the first lower buried pipe are equal, and the space of the pit is fully utilized, so that the unnecessary area of the pit is reduced, and further, the labor time consumed by pit digging is reduced.
Referring to fig. 1 and 2, in the specific structure of the first buried pipes 130, two layers of the first buried pipes 130 are both composed of a plurality of groups of pipes with a certain structure; the pipelines with a certain structure are all composed of two main straight pipes 131 with equal length and a plurality of auxiliary straight pipes 132 with equal length, the two main straight pipes 131 are placed in parallel, two ends of the auxiliary straight pipes 132 are respectively communicated with the two main straight pipes 131, and the auxiliary straight pipes 132 are also arranged in parallel to form a structure similar to an escalator; and the main straight pipes 131 in the plurality of groups of first buried pipes 130 are all parallel to each other. The two ends of the main straight pipe 131 are respectively communicated with the first fresh air inlet pipe 110 and the first fresh air outlet pipe 120, so that fresh air enters from one end and flows out from the other end.

A condensate water drain pipe 133 with an upward opening is further formed on the main straight pipe 131, and the condensate water drain pipe 133 is communicated with the main straight pipe 131 and is used for draining condensate water formed by fresh air entering the main straight pipe 131 in the main straight pipe 131; generally, the fresh air entering the main straight pipe 131 will form more condensed water at the position of the tail end of the main straight pipe 131, which is about to enter the first fresh air outlet pipe 120, so the condensed water drain pipe 133 is disposed at the end close to the first fresh air outlet pipe 120.
In the specific structure of the ground source heat pump auxiliary heating system 400 provided by the embodiment of the invention, the second buried pipe 430 is also provided with an upper layer and a lower layer, which are respectively located on the third layer 730 and the fourth layer 740, and a second upper buried pipe (not shown in the figure) located on the third layer 730 is arranged on a plane with a depth of 4 meters from the ground 700 and is opposite to the first lower buried pipe; a so-called second underground buried pipe (not shown) located at the fourth layer 740, which is provided on a plane at a depth of 5 m from the ground 700 and is opposite to the second upper buried pipe; the second upper and lower buried pipes 135 are each surrounded by a layer of earth to absorb the temperature in the earth. The second buried pipes 430 are arranged into two layers, so that the occupied area is reduced on the basis of ensuring the contact area of fresh air and a mud layer, and the second buried pipes 430 can be conveniently dug a little more deeply in a deep pit; and the difference between the two layers is 1 meter, so that the heat exchange effect between the fresh air in the second buried pipe 430 and the surrounding soil layers can not be influenced completely. The depth of the second buried pipe 430 is fully resistant to weather temperatures between-15 degrees and-25 degrees.
In addition, the second upper buried pipe and the second lower buried pipe are equal to the first lower buried pipe and the first upper buried pipe in area of the plane, the space of the pit is fully utilized, the unnecessary area of the pit is reduced, and further, the labor time consumed by digging the pit is reduced.
Referring to fig. 5, in the specific structure of the second buried pipe 430, each of the two floors 430 includes a plurality of spiral pipes 431, and the spiral pipes 431 of the upper and lower floors are sequentially arranged in a plurality of rows; the specific structure of the spiral pipeline 431 on the upper layer and the lower layer has the following characteristics: the second fresh air inlet duct 410 is communicated with the head end of the head-most spiral duct 431, the tail end of the head-most spiral duct 431 is communicated with the head end of the adjacent spiral duct 431, the same can be done in a dragon shape until the tail-most spiral duct 431 is reached, and the tail end of the tail-most spiral duct 431 is communicated with the second fresh air outlet duct 420. So that the temperature of the fresh air entering the second buried pipe 430 can be sufficiently raised to meet the temperature requirement of the fresh air flowing out of the second fresh air outlet pipe 420.
