Cooling appliances are devices designed to lower the temperature of a space or preserve food. Common examples include air conditioners, refrigerators, and fans. These appliances work by removing heat from the air or items, creating a more comfortable environment or keeping perishable goods fresh. In homes and offices, air conditioners help maintain a cool atmosphere during hot weather, while fans circulate air to provide relief. Refrigerators are essential in kitchens, keeping food safe to eat by slowing down the growth of bacteria. Together, these cooling appliances play a vital role in our daily lives, enhancing comfort and food safety.
