Natural ventilation temperature and humidity regulation device for crop ambient-temperature transporters and natural ventilation temperature and humidity regulation method thereof

Abstract

The invention discloses a natural ventilation temperature and humidity regulation device for crop ambient-temperature transporters and a natural ventilation temperature and humidity regulation method thereof. The natural ventilation temperature and humidity regulation device comprises an air conditioning carriage and a plurality of adjustable exhaust mechanisms. The air conditioning carriage comprises an adjustable ventilation mechanism, an air filter, a wet curtain cooling system, a temperature and humidity sensor, an intake valve actuator, an exhaust valve actuator, a controller, and an air speed sensor. Through the natural wet curtain ventilation device and the adjustable ventilation and exhaust mechanisms, under coordinative control of the sensor and the controller, ventilation quantity can be automatically controlled according to intake quantity and ambient temperature; accordingly, ventilation quantity in the carriage is kept relatively stable. The natural ventilation temperature and humidity regulation device can be installed at the front end of the carriage of a common transporter with no vehicular air conditioner and can also be installed on a transporter with a vehicular air conditioner; energy is saved, environment is protected, power consumption is low, and production and application costs are reduced.

Description

technical field [0001] The invention relates to intelligent control equipment for logistics transportation of agricultural products, in particular to a natural ventilation temperature and humidity regulation device and method for a normal-temperature transport vehicle of agricultural products. Background technique [0002] For a long time, the logistics cost of agricultural products in my country has been high, and the logistics cost of fresh agricultural products accounts for more than 70% of the product sales cost. According to statistics, in the normal temperature circulation of agricultural products in our country, the loss due to grade interval, transportation and processing loss reaches hundreds of billions of yuan every year. In view of the particularity of agricultural products themselves, the logistics conditions required for them have higher technical and management requirements than general non-living goods. Due to the lack of logistics equipment and cost conside...

Problems solved by technology

For example, Chinese utility model CN202764659U discloses a system that uses the airflow generated by the running of the vehicle to ventilate and cool down. It utilizes the airflow that is generated during the driving of the vehicle and is opposite to the direction of the vehicle to cool down the cabin through evaporative cooling. Refrigeration and cooling equipment, but the air volume sent into the compartment can only be determined according to the air flow introduced from the outside. The air flow is large when driving fast, and the air flow is small when driving slow. It is very likely that there will be insufficient or excessive ventilation.
