What is the principle of direct heating heat pump water heater?

Answer:

The heater heat pump water heater is arranged in a groove frame, the groove frame cannot withstand the pressure is too high, and the groove box side pole and two pole electric wire is introduced, the water pressure will be damaged if the long-term by. Therefore, the direct heating type heat pump water heater can not be made after the standard, are made before the standard. In addition, in order to ensure the safe use of heat pump water heater, no water dry, with water as the pressure sensing signal excited switch is installed in the cold water inlet, the ability to switch the diaphragm pressure sensor excited under pressure, and not for a long time under pressure, so the heat pump water heater generally made before the standard.A typical heat pump water heater is mainly composed of a heating plate, pressure sensor, power regulator, water regulation leading components such as inlet and outlet pipe, wherein the heating plate is a key component of heat pump water heater, the structure of right by the tank, a sealing ring, cover and electric components, the electric heating element in the slot board slot.
According to different heating forms, the direct heating heat pump electric water heater can be divided into the following three kinds:Exposed electric heating electric water heater;Electrothermal film heating electric water heater;Electrothermal tube heating electric water heater.
Principle of direct heating type heat pump water heater:Direct heating type heat pump water heater is also known as fast or faster heat type heat pump water heater, the basic characteristics of heat pump water heater is a hot water outlet: cold water, as long as a faucet, a few seconds in which energy sources continue to continuous supply of hot water, not hot water, turn off the tap.
The direct heat type heat pump water heater works by direct conduction heating method, because the electric heating element is placed in the groove of the groove plate, so when the cold water flows through the tank, it can flow directly through the surface of the heat element and is heated. Because the water tank is like a snake, the cold water flowing into the water inlet is gradually heated, and the hot water with higher temperature can be obtained at the water outlet.
