High-efficiency heat exchange and anti-corrosion heat pump hot water storage tank

Abstract

The invention discloses an efficient heat exchange and corrosion resistant heat pump heat accumulation water tank which comprises a heat accumulation water tank inner container, and the heat accumulation water tank inner container is provided with a water inlet, a water outlet, a circulation medium inlet and a circulation medium outlet. The efficient heat exchange and corrosion resistant heat pump heat accumulation water tank further comprises a combined type coil pipe heat exchange device arranged in the heat accumulation water tank inner container. The combined type coil pipe heat exchange device is composed of a cooling coil pipe and a heat exchange coil pipe, wherein the cooling coil pipe is arranged in the heat accumulation water tank inner container and does not make contact with the inner side wall of the heat accumulation water tank inner container, the heat exchange coil pipe is arranged in the heat accumulation water tank inner container and connected with the inner side wall of the heat accumulation water tank inner container, and the inner side wall of the heat accumulation water tank inner container becomes a heat exchange face because the heat exchange coil pipe is connected with the inner side wall of the heat accumulation water tank inner container. According to the efficient heat exchange and corrosion resistant heat pump heat accumulation water tank, the inner wall of the heat accumulation water tank inner container is fully utilized to increase the heat exchange area, the speed of corrosion of the heat accumulation water tank inner container because of high temperature of high-temperature circulation media is lowered greatly, and therefore the efficient heat exchange and corrosion resistant heat pump heat accumulation water tank has the advantages of being simple in structure, high in reliability, low in cost, efficient in heat exchange and corrosion resistant.

Description

technical field [0001] The invention relates to a hot water storage tank, in particular to a high-efficiency heat exchange and anti-corrosion heat pump used in a heat pump hot water unit and used in conjunction with a heat pump system, which can reduce the consumption of electric energy and reduce the cost of use Storage tank. Background technique [0002] The existing hot water storage tanks with heat exchange coils or heat exchangers on the market can basically be classified into three categories. The first type is that the coils are directly placed in the hot water storage tanks, and the coils are not in contact with the inner tank. Contact with water to heat water, although the efficiency is high, but the selection of ordinary coils is easy to corrode, while the selection of corrosion-resistant coils is expensive and difficult to market; the second type is external coils, which are installed in the inner tank of the hot water storage tank The outer surface is wrapped ar...

[0002] The existing hot water storage tanks with heat exchange coils or heat exchangers on the market can basically be classified into three categories. The first type is that the coils are directly placed in the hot water storage tanks, and the coils are not in contact with the inner tank. Contact with water to heat water, although the efficiency is high, but the selection of ordinary coils is easy to corrode, while the selection of corrosion-resistant coils is expensive and difficult to market; the second type is external coils, which are installed in the inner tank of the hot water storage tank The outer surface is wrapped around the heat exchange coil. This method can reduce the cost and eliminate the corrosion of the water on the coil, but the heat exchange efficiency of this method is low; There is also an inner tank, the innermost inner tank is a hot water storage tank, the heat exchange medium is installed between the two inner tanks, and the jacket is actually a heat exchanger. This method has complex structure, low reliability and high cost. Low heat transfer efficiency
