DC-BUS for Appliances
Wiring plays a significant role in White goods such as refrigerators, Air conditioners, Washing machines etc. Reducing wires saves weight, cost and space while increasing reliability. While the copper becomes rare and expensive, the silicon is widely available and the cost of silicon semiconductors is decreasing. Using the AC/DC-BUS simplify the installation; reduce the manpower required to assemble the appliances and its installation (air conditioner). Allow common modules for many models of same appliance. The maintenance becomes much simpler using the communication capabilities between the modules.
Modular Refrigerator AC-DC BUS
Modular architecture for a Refrigerator based on AC-DC BUS is described hereby. This architecture is applicable to other White good products such as Dishwashers, Washing machines where complicated harness is used. A Refrigerator consists of a main controller (Master) that controls the operation of all the modules such as Compressor, Heater, Relays, while reading sensors such as Temperature, door switches etc (Slaves). Using the AC-DC Bus, all these modules are connected to a single harness consisting only 4 wires 24V and 110V/230V. The data between the modules is transferred over the 24V supply line.
Air conditioner distributed network
In an Air conditioning system, the communication between the outside and the inside units, can be made reliably, by using the DC-BUS technology. By adding Yamar’s devices to each unit, one can remove the controlling wires and control many units that are connected over the same power line.
