Description

Technical Field

[0001] The invention relates to the technical field of incubators, and in particular to an air energy incubator system and a control method. Background Art

[0002] Hatching equipment is one of the important equipment in modern chicken farming equipment. The whole set of hatching equipment includes incubators, hatchers and other supporting devices. An incubator is a machine that artificially simulates the maternal nature of oviparous animals to develop fertilized eggs into life after a certain period of time under conditions such as temperature, humidity and egg turning. There are many types of incubators. Although the degree of automation and capacity are different, their structural principles are basically the same. They are mainly composed of the body, active temperature control device, active humidity control device, active egg turning device and ventilation device.

[0003] Traditional incubators use electric heating with high energy consumption and low stability, resulting in low hatching quality. Therefore, there is a need for an air energy incubator system and control method that is energy-saving and energy-efficient with a heat pump incubation, uses frequency conversion technology, and can also ensure the quality of hatching. Summary of the invention

[0004] The purpose of the present invention is to provide an air energy incubator system which is energy-saving and energy-efficient, adopts frequency conversion technology to ensure the quality of incubation, and flexibly adjusts the air volume and wind direction through precise intelligent control to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an air energy incubator system, comprising a variable frequency compressor, a condenser, a condensing variable frequency EC fan, an electronic expansion valve, an evaporator, an evaporating variable frequency EC fan, an air duct 1, an air duct 2, an air duct 3, a temperature sensor 1, a temperature sensor 2, a temperature sensor 3, a temperature sensor 4, an egg rack, a vent A, a vent B, a vent C, a vent D, a vent E, a vent F, an exhaust port I and an air supply port H,

[0006] A vent B is provided above the egg rack, and the vent B is connected to the air duct 2 and the exhaust port I in sequence. A condensing variable frequency EC fan is installed on the left side of the exhaust port I. A condenser is installed on the left side of the condensing variable frequency EC fan. The upper and lower ends of the condenser are respectively connected to the lower end of the evaporator and the variable frequency compressor through pipelines;

[0007] A vent D and a vent A are respectively arranged on the left and right sides below the egg rack, and the vent A is connected to the air duct three.

[0008] Furthermore, an electronic expansion valve is installed on the pipeline between the condenser and the evaporator, and a temperature sensor 1 is installed on the upper right side of the vent B.

[0009] Furthermore, the upper end of the evaporator is connected to the variable frequency compressor through a pipeline.

[0010] Furthermore, a vent C is provided at the upper left of the egg rack, and a temperature sensor 2 is installed on the left side of the vent C. A vent E and an air supply port H are sequentially provided on the air duct 1 on the left side of the vent C.

[0011] Furthermore, the egg rack is configured as an array structure with arc-shaped grooves.

[0012] Furthermore, temperature sensor 4 and temperature sensor 3 are installed on the left sides of the vent A and the vent D respectively.

[0013] Furthermore, an evaporator is installed on the left side of the ventilation port D, and an evaporative variable frequency EC fan is installed on the left side of the evaporator, and a ventilation port F is arranged at the lower left of the evaporative variable frequency EC fan.

[0014] A control method for an air energy incubator system comprises the following steps:

[0015] Step 1: The variable frequency compressor starts, and the high-temperature refrigerant reaches the condenser through the pipeline. The condensing variable frequency EC fan discharges the heat to the inlet. At this time, vents A and C are closed, and vents B and D are opened. The high-temperature refrigerant passes through the condenser, reaches the electronic expansion valve, and then reaches the evaporator, and then returns to the variable frequency compressor for energy recovery;

[0016] Step 2: When the vents and vent C are closed, and vents B and vent D are opened, the heat is blown downward through vent B and then sucked back from vent D. At this time, the upper part of the eggs is heated for incubation. When the conditions meet the control requirements, the wind direction is switched. At this time, vents A and vent C are opened, and vents B and vent D are closed. At this time, the heat is blown upward through vent A and then sucked back from vent C for heat recovery.

[0017] Step 3. Calculate the time to switch wind direction according to the temperature and time of the incubator. When the machine is turned on for incubation again, vents A and C are closed, vents B and D are opened, and high-temperature hot air first enters from vent B, then passes through the incubated object and is sucked back from vent D. As the temperature rises, when the humidity, temperature and time meet the requirements, switch the wind direction, vents A and C are opened, vents B and D are closed, and high-temperature hot air first enters from vent A, then passes through the incubated object and is sucked back from vent C.

[0018] Before the step starts, the temperature and humidity in the box are detected first, and the initial rotation speed of the condensing variable frequency EC fan and the evaporating variable frequency EC fan is determined according to the current box temperature. At the same time, the maximum rotation speed and the minimum rotation speed are designed. When the humidity does not meet the hatching requirements, the variable frequency compressor stops starting. At this time, humidification is performed. After the requirements are met, the fluctuation is maintained within 5% for three minutes. At this time, the variable frequency compressor is started, and the return air temperature difference is checked. When the outlet air temperature difference is greater than the set temperature, the condensing variable frequency EC fan and the evaporating variable frequency EC fan increase the rotation speed. At this time, the frequency of the variable frequency compressor remains unchanged. When the rotation speed of the condensing variable frequency EC fan and the evaporating variable frequency EC fan reaches the maximum value, the temperature difference is still large. The variable frequency compressor reduces the frequency according to the temperature difference until the set temperature value is reached. After it remains stable, the frequency is changed according to the actual situation. The fan remains unchanged at this time;

[0019] When the air outlet temperature is less than the set temperature, the condensing variable frequency EC fan and the evaporating variable frequency EC fan will reduce speed, and the variable frequency compressor frequency will increase until the air outlet temperature reaches the set value, and the compressor frequency will be reduced;

[0020] The humidity is tested every 10 seconds. When the humidity is lower than the set value, the humidification mode is turned on. When it reaches the set value and remains unchanged for 1 minute, the humidification mode is exited. When the humidity is higher than the set value, the fresh air dehumidification function is turned on, the exhaust port I and the air intake port H are opened, the humidity of the incubator is first reduced, and then the incubation mode is started.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the air energy incubator system adopts a method of evenly supplying air from top to bottom to ensure that the incubated eggs are heated evenly, avoids periodic turning of eggs and saves manpower, and judges the speed of the fan by controlling the humidity and the temperature difference between the supply air and the return air, thereby determining the fresh air volume and the exhaust air volume, further ensuring the reliability of the machine; the energy efficiency is above 3.0, and precise control logic is adopted to switch the wind direction at the right time, and the air volume is controlled by an intelligent algorithm to ensure product quality; a fully enclosed heat recovery system is adopted to recover most of the heat, and no matter the air is supplied from the bottom or from the top, it will eventually pass through the evaporator for heat recovery, which is more energy efficient than traditional electric heating incubators, and is energy-saving and environmentally friendly.

[0029] A vent B is provided above the egg rack 14 for passing gas from above into the egg rack 14, and the vent B is connected to the air duct 2 8 and the exhaust port 1 in sequence. A condensing frequency conversion EC fan 3 is installed on the left side of the exhaust port 1. The condensing frequency conversion EC fan 3 adopts an EC motor, which has the characteristics of high intelligence, high energy saving, high efficiency, low vibration, low noise and continuous and uninterrupted operation, and can ensure the perfect operation of the device. A condenser 2 is installed on the left side of the condensing frequency conversion EC fan 3 for cooling the high-temperature refrigerant to make it low temperature. The upper and lower ends of the condenser 2 are respectively connected to the lower end of the evaporator 5 and the variable frequency compressor 1 through pipelines, and the upper end of the evaporator 5 is connected to the variable frequency compressor 1 through a pipeline. The variable frequency compressor 1 controls the speed of the compressor through a power supply with a variable frequency, and different speeds output different cooling capacities to adjust the temperature. An electronic expansion valve 4 is installed on the pipeline between the condenser 2 and the evaporator 5, and a temperature sensor 10 is installed on the upper right side of the vent B. The evaporator 5 is used to convert the low-temperature refrigerant generated by the condenser 2 into a high-temperature refrigerant.

[0030] Ventilation holes D and ventilation holes A are respectively arranged on the left and right sides below the egg rack 14, and ventilation holes A are connected to the air duct three 9. Temperature sensors four 13 and three 12 are respectively installed on the left sides of ventilation holes A and ventilation holes D; an evaporator 5 is installed on the left side of ventilation holes D, and an evaporation variable frequency EC fan 6 is installed on the left side of the evaporator 5, and a vent F is arranged on the lower left side of the evaporation variable frequency EC fan 6 for transmitting the gas blown out by the evaporation variable frequency EC fan 6;

[0031] A vent C is provided at the upper left of the egg rack 14, and a temperature sensor 11 is installed on the left side of the vent C for detecting the temperature coming out of the vent C. A vent E and an air supply port H are sequentially provided on the air duct 7 on the left side of the vent C. By providing four temperature sensors, the temperature of the air in the equipment can be monitored in real time and the air can be controlled in time.

[0032] The control method of the air energy incubator system comprises the following steps:

[0033] Step 1: The variable frequency compressor 1 starts, and the high-temperature refrigerant reaches the condenser 2 through the pipeline. The condensing variable frequency EC fan 3 discharges the heat to the inlet. At this time, the vents A and C are closed, and the vents B and D are opened. The high-temperature refrigerant passes through the condenser 2, reaches the electronic expansion valve 4, and then reaches the evaporator 5, and then returns to the variable frequency compressor 1 for energy recovery;

[0034] Step 2: When vents A and C are closed, and vents B and D are opened, the heat is blown downward through vent B and then sucked back from vent D. At this time, the upper part of the eggs is heated for incubation. When the conditions meet the control requirements, the wind direction is switched. At this time, vents A and C are opened, and vents B and D are closed. At this time, the heat is blown upward through vent A and then sucked back from vent C for heat recovery.

[0035] Step 3. Calculate the time to switch wind direction through the temperature and time of the incubator. When the machine is turned on for incubation again, vents A and C are closed, vents B and D are opened, and high-temperature hot air first enters from vent B, then passes through the incubated object, and is sucked back from vent D. As the temperature rises, when the humidity, temperature and time meet the requirements, switch the wind direction, vents A and C are opened, vents B and D are closed, and high-temperature hot air first enters from vent A, then passes through the incubated object, and is sucked back from vent C. Changing the wind direction improves the safety of the incubated object and saves time for manual egg turning.

[0036] Before step 1, it is necessary to detect the temperature and humidity in the box before starting the machine. According to the current box temperature, the initial speed of the condensing variable frequency EC fan 3 and the evaporating variable frequency EC fan 6 is determined to prevent the air volume from being too large, resulting in the temperature not rising in the early stage. At the same time, the maximum speed and the minimum speed are designed. When the humidity does not meet the hatching requirements, the variable frequency compressor 1 stops starting. At this time, humidification is carried out to ensure that after meeting the requirements, the fluctuation is maintained within 5% for three minutes. At this time, the variable frequency compressor 1 is started, and the return air temperature difference is checked. When the outlet air temperature difference is greater than the set temperature, the condensing variable frequency EC fan 3 and the evaporating variable frequency EC fan 6 increase the speed. At this time, the frequency of the variable frequency compressor 1 remains unchanged. When the speed of the condensing variable frequency EC fan 3 and the evaporating variable frequency EC fan 6 reaches the maximum value, the temperature difference is still large. The compressor 1 reduces the frequency according to the temperature difference until the set temperature value is reached and remains stable. Then, the frequency is changed according to the actual situation. The fan remains unchanged at this time.

[0037] When the air outlet temperature is less than the set temperature, the condensing variable frequency EC fan 3 and the evaporating variable frequency EC fan 6 reduce their speeds, and the frequency of the variable frequency compressor 1 increases until the air outlet temperature reaches the set value, and the compressor reduces its frequency.

[0038] The humidity is tested every 10 seconds. When the humidity is lower than the set value, the humidification mode is turned on. When the humidity reaches the set value and remains unchanged for 1 minute, the humidification mode is exited. When the humidity is higher than the set value, the fresh air dehumidification function is turned on, the exhaust port I and the air intake port H are opened, the humidity of the incubator is first reduced, and then the incubation mode is started. Through multi-directional and precise control, product quality and efficiency are guaranteed.
