Embodiment Construction
[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0029] see figure 1 As shown, according to an embodiment of the present invention, a water tank for a heat pump water heater is provided. The water tank of the heat pump water heater includes a shell 10 , an inner tank 20 and a coil 30 . Wherein, the housing 10 is surrounded to form a receiving chamber; the inner tank 20 is arranged in the receiving chamber; There is an empty part, at this moment, the distance between the lowest point of the coiled pipe 30 and the bottom end of the liner 20 is h=H×α×β×γ. Wherein, H is the height of the inner tank 20, α is the height conversion coefficient of the inner tank 20, and α is in the range of 0.20 to 0.50; β is the diameter conversion coefficient of the inner tank 20, and β is in the range of 0.20 to 0.30...

The invention provides a water tank for heat-pump water heaters, a design method of the water tank and a heat-pump water heater. The water tank comprises a housing, a liner and a coil; the housing encloses a holding cavity; the liner is disposed in the holding cavity; the coil is disposed in the holding cavity and winds outside the liner. A distance h from a lowest point of the coil to the bottom end of the liner is H*Alpha*Beta*Nu; H is height of the liner; Alpha is conversion coefficient of the height of the liner and ranges from 0.20 to 0.50; Beta is conversion coefficient of the diameter of the liner and ranges from 0.20 to 0.30; Nu is a correction coefficient of the distance h from the lowest point of the coil to the bottom end of the liner and ranges from 0.80 to 1.00. The performance of a unit with the water tank can be improved, system running load is reduced, and running reliability of the unit is guaranteed.
Description
technical field [0001] The invention relates to the technical field of water heaters, and more specifically, to a heat pump water heater water tank, a design method for the heat pump water heater water tank, and a heat pump water heater. Background technique [0002] Patent No. CN200920237716.8 discloses a gall wall heat exchange inner tank. This inner tank body only limits the inner tank body structure, and does not require related coils, etc., only through the inner tank body structure Designed to improve heat transfer efficiency. [0003] Most of the water tanks of heat pump water heaters on the market are of the outer coil type, and there are various ways of outer coils, and there is no fixed form. Double-convex water tanks usually coil the coil near the bottom of the water tank to reduce the capacity of cold water at the bottom, and this method is not the best solution for single-convex water tanks. [0004] The existing single-convex water tank coils the coil near th...
