Description

Technical Field

[0001] The utility model relates to the technical field of grain depot temperature control machines, in particular to a variable frequency anti-corrosion grain surface temperature control and air conditioning integrated machine. Background Art

[0002] At present, the grain warehouse cooling units on the market are all fixed-frequency units, which all operate at a fixed speed and cannot output cooling capacity according to actual demand, which easily leads to energy waste; the temperature fluctuates greatly when the fixed-frequency air conditioner adjusts the temperature and humidity, and cannot accurately adjust the temperature in the warehouse, affecting the quality of grain; the fixed-frequency air conditioner is noisy due to its fixed speed operation; the starting current of the fixed-frequency air conditioner is large, which has a great impact on the power grid and may cause a heavy burden on the power grid; when the fixed-frequency air conditioner adjusts the temperature and humidity, under the condition that the target temperature and humidity are reached, the air conditioner will frequently start and stop at the temperature difference above and below the target temperature, causing greater wear on transmission components such as the compressor and fan, resulting in a shortened machine life; the cooling effect of the fixed-frequency air conditioner is reduced at higher temperatures, and it cannot adapt to relatively harsh practical environments.

[0003] High energy consumption: Non-inverter air conditioners operate at a fixed power and cannot flexibly adjust power according to actual demand. They consume the same amount of electricity even when the load is low, resulting in energy waste.

[0004] Large temperature fluctuations: Since the cooling or heating output power cannot be automatically adjusted, the temperature inside the grain warehouse is prone to large fluctuations, making it difficult to accurately maintain a stable temperature and humidity environment, which may affect the storage quality of grain.

[0005] Frequent start and stop: In order to reach the set temperature, non-inverter air conditioners will frequently start and stop the compressor, which will not only shorten the service life of the compressor, but may also cause a greater impact on the power grid at the moment of start and stop.

[0006] Loud noise: Frequent starting and stopping and continuous operation at high power will result in relatively loud noise, which may have an adverse impact on the working environment of the grain warehouse.

[0007] Poor adaptability: When the external ambient temperature changes greatly or the grain warehouse load changes frequently, non-variable frequency air conditioners are difficult to quickly and effectively adjust their operating status to maintain stable temperature and humidity in the grain warehouse.
