• Pre-failure management of cooling equipment at mushroom growers

The period of culturing the mushroom bacteria in the medium factory that produces the mushroom medium varies depending on the type of mushroom. Usually, the cultivation period for oyster mushrooms is 1 month, and for shiitake mushrooms, 4 to 5 months depending on the variety is relatively long.

The medium managed in the culture room or growth room is not a small amount, from tens of millions to hundreds of millions of won.

The optimal culture temperature for the culture room is 20℃, and the optimal temperature for the growth room varies depending on the mushroom species, but it is usually managed at a low temperature of about 10-20℃.

Huge damage due to air conditioner failure

Although there are some differences, mushroom bacteria are often killed or seriously damaged when exposed to high temperature and room temperature.

In the case of mushroom growers, when the air conditioner fails in summer, the room temperature rises rapidly within a few hours. In this process, the room temperature rise due to the inflow of high-temperature outdoor air is unavoidable, and the rate of increase in the indoor temperature rises sharply faster than the rate of rise in other buildings, such as the rise in temperature due to respiration heat generated during the respiration process and heat loss in buildings due to the difference between indoor and outdoor temperatures. .

For this reason, the breakdown of air conditioning equipment in summer often leads to serious property damage.

Moreover, due to the nature of these air conditioners, it takes a considerable period of time to fix the cause and requires the skills of experts in the relevant field, so it is difficult to find workers in an emergency.

However, when the heating, ventilation, humidification, etc. are stopped due to a malfunction, there is no problem in the mushrooms and emergency measures such as repair, exchange and replacement with similar facilities are easy in the case of a short period of time.

Pre-diagnosis function before failure of cooling equipment

As mentioned above, it is most important to manage the failure of the air conditioner in a high temperature in summer so that it does not break down as a serious situation. In general, large-scale growers with many air-conditioning facilities have a separate professional manager or manage it under a service contract with an external professional company. Companies also fill in time only formally, which is not effective.

Therefore, by combining our patented technology (patent name: Plant Cultivation and Air Conditioning Facility) with smart farm communication technology, it is a system that manages the complex environment controller of a grower and multiple refrigeration systems installed by each grower into one. A monitoring computer installed inside the outdoor unit. Logic is a function that detects abnormal signs inside the equipment before failure based on the operation data of various sensors installed in the main circuit of the refrigeration system and notifies the facility manager of the relevant information. It is a technology to prevent failure in advance.

Sensors installed inside the outdoor unit cooling unit and fault diagnosis
① High and low pressure sensors: installed on high and low pressure pipes of the gas system to notify when the set pressure is deviating
② Noise sensor: The noise measurement of the compressor and condenser cooling fan is also notified at the setting db or higher.
③ Current sensor: Measure current by phase of power supply Short circuit of three-phase power Notifies when the set value exceeds the set value due to equipment failure, etc.
④ Temperature sensor: By measuring the temperature of the suction and discharge part of the compressor, it is possible to determine whether the amount of gas filling, whether the evaporator and condenser are operating normally, or whether the refrigerator is overheating.
In addition, it notifies the contents when the set temperature corresponding to the optimum operation condition is deviated.
Technology that installs these sensors in air-conditioning and air conditioning systems and sets preset values suitable for each room’s operating conditions, such as cultivation and cultivation rooms, and notifies the contents of regular monitoring when deviations from the set values
