Description

Technical Field

[0001] This utility model relates to the technical field of constant temperature and humidity heat pump units, specifically a constant temperature and humidity heat pump unit for planting. Background Technology

[0002] A constant temperature and humidity heat pump unit is a device that integrates heating, cooling, and humidity control, and is widely used in environments with high temperature and humidity requirements. It not only provides the necessary temperature environment but also regulates air humidity, thereby ensuring stable environmental conditions and preventing the impact of external climate changes on the environment. In some planting areas, especially in greenhouse cultivation and precision agriculture, the application of constant temperature and humidity heat pump units is also very important. Plants are very sensitive to changes in environmental conditions, especially temperature and humidity. A constant temperature and humidity heat pump unit can provide a stable growing environment, thereby promoting plant growth and increasing yield. Existing constant temperature and humidity heat pump units mainly focus on temperature and humidity regulation, but do not address other key factors for plant growth (such as carbon dioxide concentration), and therefore cannot effectively assist in plant growth.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a constant temperature and humidity heat pump unit for planting, comprising: a housing 1 with an air inlet 2 at one end; a cooling and dehumidifying section located inside the housing 1 near the air inlet 2, the cooling and dehumidifying section including an evaporator 5 fixed inside the housing 1 and a wet film 6 placed on one side of the evaporator 5, the top of the wet film 6 being provided with a spray section; an air duct 11 positioned in the air outlet direction of the spray section, a heater 10 installed inside the air duct 11, the heater 10 being a PTC heater, and a fan 13 fixedly connected to one side of the air duct 11. The input end of fan 13 is connected to air duct 11; air duct 2 14 is fixed to the output end of fan 13, and an air outlet pipe 16 is installed at one end of air duct 2 14. A carbon dioxide generator 17 is installed at the bottom of air outlet pipe 16 to increase the carbon dioxide content in the planting area. The structure of carbon dioxide generator 17 adopts the existing setting scheme. For details, please refer to the patent document with patent number 202210449053.6; heat exchange cylinder 19 is fixed inside the box 1. A connector for introducing high temperature Freon is installed on the top of heat exchange cylinder 19, and a water inlet 21 is installed on one side of heat exchange cylinder 19.

[0016] It should be noted that in this embodiment, a controller is provided, and a pyramidal connecting duct is installed between the evaporators 5. Temperature and humidity sensors are fixed inside the connecting duct and inside the duct 11. The air inlet 2 and the air outlet 16 are connected to the air duct of the planting space. Under the action of the fan 13, the air in the planting space enters the evaporator 5 through the air inlet 2. The air is cooled by the low temperature of the evaporator 5. When the humidity is high, the moisture in the air is liquefied by the low temperature of the evaporator 5. The liquefied water droplets are collected below. When the air passes through the duct 11, when the temperature is low, the heater 10 heats the passing air. After the air is heated, it enters the air outlet 16 through the fan 13. There is a carbon dioxide concentration detection device inside the planting space. When the concentration is low, the controller controls the solenoid valve of the carbon dioxide generator 17 to open, so that the carbon dioxide is discharged into the planting space through the air outlet 16. This realizes the circulation treatment of the air in the planting space, which can remove dust, heat, cool down and dehumidify it.

[0017] In one embodiment, a filter screen 3 is installed on one side of the housing 1, a heat dissipation vent is opened at the end of the housing 1 away from the air inlet 2, an ultraviolet germicidal lamp 12 is embedded inside the air duct 11, and a filter screen 15 is installed inside the air duct 14.

[0018] It should be noted that in this embodiment, filter screen 3 is installed in the connecting air duct on one side of the air inlet 2. Filter screen 3 is a polyester fiber filter screen used to filter large particles. Air enters the air duct 11 and comes into contact with the ultraviolet germicidal lamp 12. The air is sterilized by the ultraviolet germicidal lamp 12. Then the air is blown into the air duct 2 14 by the fan 13. A filter box is installed inside the air duct 2 14. Filter screen 2 15 is installed inside the filter box. Filter screen 2 15 is made of HEPA filter material.

[0019] In one embodiment, the spray unit includes a circulating water tank 9 installed at the bottom of the wet film 6, a water tank connected to the circulating water tank 9 is fixedly connected to the bottom of the evaporator 5, a water pump 8 is installed on one side of the circulating water tank 9, the input end of the water pump 8 is connected to the circulating water tank 9, and a spray pipe 7 is fixedly connected to the output end of the water pump 8, with the spray pipe 7 located above the wet film 6.

[0020] It should be noted that in this embodiment, when the temperature and humidity sensor inside the connecting duct detects low air humidity, the controller controls the water pump 8 to operate. The water pump 8 sprays water from the circulating water tank 9 onto the wet membrane 6 through the spray pipe 7. As air passes through the gaps between the multiple wet membranes 6, it comes into contact with the water, thus achieving humidification. Excess water flows along the wet membrane 6 into the circulating water tank 9, thus circulating.

[0021] In one embodiment, an outdoor unit is provided at one end of the housing 1. The outdoor unit has an air vent for air intake. A condenser 18 and a fan for cooling the condenser 18 are installed inside the outdoor unit. A compressor 4 connected to a heat exchange cylinder 19 and an evaporator 5 is installed in the outdoor unit. An inner cylinder 20 is fixedly connected to the top of the inner wall of the condenser 18. One end of the inner cylinder 20 is inserted into the inner cylinder 20. A spiral tube 22 is wound around both the water inlet 21 and the outer side of the inner cylinder 20. The two ends of the spiral tube 22 are connected to the Freon in the refrigeration system through connectors.

[0022] It should be noted that in this embodiment, the refrigeration system includes a compressor, an evaporator, a condenser, an expansion valve, and a four-way valve. Both the evaporator and condenser are connected to the compressor. The expansion valve is installed between the condenser and evaporator to regulate the refrigerant flow and pressure. The four-way valve is used to change the refrigerant flow direction and adjust the cooling and heating modes. The refrigeration system piping is connected to both ends of the spiral tube 22 via a reversing valve and a connector. The water inlet pipe inside the planting space is connected to the water inlet 21, and the water outlet pipe is connected to one side of the top of the heat exchange cylinder 19. The internal components of the water pipes need to be inspected. When heating, water enters the inner cylinder 20 through the inlet 21, spreads downwards from the inner cylinder 20, then enters the bottom of the heat exchange cylinder 19 through the bottom of the inner cylinder 20, and then spreads upwards inside the heat exchange cylinder 19, allowing it to be discharged through the outlet pipe on one side of the heat exchange cylinder 19. During this period, under the action of the reversing valve, the high-temperature Freon of the refrigeration system enters the spiral tube 22 inside the inner cylinder 20 through the connector, then flows into the spiral tube 22 outside the inner cylinder 20 and then flows back into the refrigeration system through the connector, thereby heating the water pipe through heat exchange.
