Air-cooled VS straight-cooled which refrigerator is more suitable for you?

Many consumers now choose the refrigerator to hear the salesman's "wind and frost-free" sales term, its biggest selling point is no frost. In fact, air-cooled refrigerators (hereinafter referred to as "air-cooled refrigerators") are relative to traditional direct-cooling refrigerators (hereinafter referred to as "straight-cooled refrigerators"). So how do you choose these two types of refrigerators?

Monocrystalline Solar Panel

Sunlight shines on the p-n junction of the semiconductor to form new hole-electron pairs. Under the action of the electric field of the p-n junction, the holes flow from the n region to the p region, and the electrons flow from the p region to the n region. After the circuit is turned on, a current is formed. This is how photoelectric effect monocrystalline silicon solar panels work.
Application fields:
1. Household lamp power supply: such as garden lamps, street lamps, portable lamps, camping lamps, mountaineering lamps, fishing lamps, black light lamps, rubber tapping lamps, energy-saving lamps, etc.
2. Photovoltaic power station: 10KW-50MW independent photovoltaic power station, wind-solar (firewood) complementary power station, various large parking plant charging stations, etc.
3. Solar buildings: Combining solar power generation with building materials to make future large buildings self-sufficient in electricity is a major development direction in the future.
4. Other fields include (1) Supporting cars: solar cars/electric cars, battery charging equipment, car air conditioners, ventilation fans, cold drink boxes, etc.; (2) Solar hydrogen production plus fuel cell regenerative power generation system; (3) Sea water Power supply for desalination equipment; (4) Satellites, spacecraft, space solar power plants, etc.
