Enamel inner container water tank with condenser

Abstract

An enamel inner container water tank with a condenser is characterized in that: a case is arranged outside an end of the enamel inner container of a water tank, the case includes a seal head with a larger size, and a cylinder body, and likes a haft inner container which is radially cut open with a diameter greater than that of the enamel inner container; the case covers the enamel inner container from the end of the enamel inner container, an opening position of the case is connected to a circular rack which is arranged on a cylinder body of the enamel inner container and decides the size of a gap, and the case and a part of the enamel inner container covered by the case form a finite space; the finite space is the condenser of a heat-pump water heater. An enough heat exchanging area is arranged between the condenser and the enamel inner container, so that heat exchanging is fluent, and the energy efficiency ratio and the cost performance of a whole enamel inner container water tank can be improved. The enamel inner container water tank is small in size, can control the flow of hot water in cooperation with a heat pump machine, and can become an instant heating type heat-pump water heater; and the hot water capacity can transcend that of the other volumetric water heaters.

Description

Technical field [0001] The invention relates to a hot water storage tank of a pressure-bearing heat pump water heater. Background technique [0002] Usually, the enamel inner tank of the heat pump water heater contains a condenser, and the condenser is mostly in the form of a metal coil. The coil is usually made of pure copper because of the large thermal conductivity, and for the sake of water safety, the coil has to be wrapped in enamel. On the outer wall of the inner tank, the heat exchange effect is not good, and the "energy efficiency ratio" is low, and the coil is made of expensive pure copper, so that this kind of enamel tank with a condenser is not cost-effective. SUMMARY OF THE INVENTION [0003] The invention provides an enamel inner tank water tank containing a condenser, which aims to improve the heat exchange efficiency to ensure a high energy efficiency ratio, and to reduce the material cost and improve the product cost performance. [0004] The technical so...

[0002] Usually, the enamel liner water tank of the heat pump water heater contains a condenser, and the condenser is mostly in the form of a metal coil. The coil is usually made of pure copper because of the need for a large thermal conductivity, and the coil has to be wound on the enamel for the sake of water quality safety. On the outer wall of the inner tank, the heat exchange effect is poor and the "energy efficiency ratio" is low, and the coil is made of expensive pure copper, which makes this type of enamel inner tank with a condenser less cost-effective
