Baffle plate type bearing water tank

Abstract

A baffle type pressure water storage tank is characterized in that a cold water port is formed in an inner container of a water tank and positioned at the bottom part of the inner container of the water tank, and a hot water port is positioned at the top part of the inner container of the water tank; baffles are respectively arranged on the left and the right side walls of the inner container of the water tank, the upper and the lower adjacent baffles are respectively positioned on the left and the right positions in the inner container of the water tank, a water flow channel is formed between the two adjacent baffles, and a circuitous flow channel is formed between the outer edges of the baffles and the side walls of the inner container of the water tank. The baffle type pressure water storage tank can not only retain the advantages on the water supply pressure aspect of the pressure water tank, but also effectively improve the hot water efficiency, simultaneously simplify the structure, reduce the cost and miniaturize the water tank.

Description

technical field [0001] The invention relates to a water storage device of a heat pump water heating unit using air as a heat source, in particular to a pressurized water storage tank in the heat pump water heating unit. Background technique [0002] The water storage tanks of the existing air source heat pump hot water units are divided into two types: pressure-bearing type and non-pressure-bearing type. [0003] The non-pressurized water storage tank uses a water supply pump to supply hot water, and the hot water utilization rate is high, up to 100%, but it needs to be equipped with a water supply pump, so it has the following disadvantages: [0004] 1. It is difficult to match the water supply pressure of the water supply pump with the tap water pressure, and it is difficult to mix the water during use; [0005] 2. The weight and volume of the water supply pump are large, which is not conducive to the miniaturization of the unit; [0006] 3. The price of the water supply...

AI Technical Summary

Problems solved by technology

[0004] 1. It is difficult to match the water supply pressure of the water supply pump with the tap water pressure, and it is difficult to mix the water during use;

[0005] 2. The weight and volume of the water supply pump are large, which is not conducive to the miniaturization of the unit;

[0006] 3. The price of the water supply pump is high, which increases the design cost of the unit;

[0007] 4. The power of the water supply pump is relatively large, which increases the cost of the unit

However, the entire inner cavity of the traditional pressure-bearing water storage tank has no separation. After the tap water enters the inner cavity of the water storage tank at the water inlet at the bottom of the water storage tank, the cold water and hot water are quickly convected and mixed in a large area across the entire inner cavity of the water tank. As a result, the temperature of hot water drops rapidly, so that it cannot be used, and the utilization rate of hot water is very low

To ensure the amount of hot water used, the volume of the water tank needs to be made large, resulting in increased costs, increased installation space, and increased heat preservation energy consumption of the water tank
