Water tank of air-energy heat pump water heater

Abstract

The invention discloses a water tank of an air-energy heat pump water heater, which comprises a shell, an inner container, a heat exchanger, a tap water inlet pipe, a hot water outlet pipe and a temperature control system. The heat exchanger is a parallel type heat exchanger disposed in an inner cavity of the inner container and is provided with a first branched heat exchanger and a second branched heat exchanger, the first branched heat exchanger is connected with the second branched heat exchanger by a first flow divider, the inner container is divided into an upper hot water cavity and a lower cold water cavity by the first branched heat exchanger, the second branched heat exchanger is disposed in the hot water cavity, and both the first branched heat exchanger and the second branched heat exchanger are connected with a second flow divider; one end of the tap water inlet pipe is arranged in the cold water cavity of the inner container and provided with a sprinkler type water outlet capable of discharging water downwards, and the other end of the tap water inlet pipe is disposed on the outer portion of the shell and connected with a one-way relief valve; and the temperature control system is inlaid in the shell. A heating effect is unaffected when pressure of refrigerant inside the heat exchanger is increased, cold water and hot water are separated from each other to prevent the hot water from cooling to affect a service effect of the hot water, tap water is also prevented from being directly mixed with the hot water, and the water tank has the advantages of high-efficiency heating capability, energy conservation and simple structure.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to the technical field of an air energy heat pump water heater water tank. Background technique [0002] The traditional air energy heat pump water heater tank has two types of internal heat exchangers: series heat exchanger and parallel heat exchanger. Both the series heat exchanger and the parallel heat exchanger are completely normally open heat exchangers. As the pressure of the refrigerant inside the water tank heat exchanger increases to the critical point, the operation effect of the entire air energy heat pump water heater system will be affected, resulting in Ineffective heating and wasted energy. The nozzle of the tap water inlet pipe directly upwards or bends downward to discharge water. The disadvantage is that the mixing of tap water and hot water causes the water temperature to drop, which affects the effect of hot water. The heat exchanger is in the sh...

Problems solved by technology

Both the series heat exchanger and the parallel heat exchanger are completely normally open heat exchangers. As the pressure of the refrigerant inside the water tank heat exchanger increases to the critical point, the operation effect of the entire air energy heat pump water heater system will be affected, resulting in Ineffective heating and wasted energy

The nozzle of the tap water inlet pipe directly upwards or bends downward to discharge water. The disadvantage is that the mixing of tap water and hot water causes the water temperature to drop, which affects the effect of hot water.

The heat exchanger is in the shape of bamboo rafts or spirally wound, and its heating effect is not good
