Problems solved by technology

[0002] In the prior art, the hot water storage tanks of heating devices such as boilers or heat pumps generally have two types: closed and open. The closed water tank has heat stratification effect and high heat release efficiency, but it is a kind of pressure vessel, which must meet the relevant pressure. Container regulations require manufacturing and regular inspections every year. The manufacturing and maintenance costs are much higher than that of open hot water storage tanks. In addition, the amount of hot water supplied is equal to the amount of replenished water. Partial heating and rapid hot water storage cannot be controlled.
The open water tank has a simple structure and low cost. It is suitable for heat storage heating devices such as heat pumps and electric heaters that require a large amount of hot water storage. The water is completely mixed to reduce the hot water supply temperature and reduce the heat release efficiency of the water tank; in addition, the tank has no heat stratification effect, and all the hot water needs to be heated at the same time, resulting in a slow rise in the temperature of the hot water, especially when the demand for different hot water storage is different. When multiple hot water storage tanks are connected in parallel, the temperature rise rate of the hot water produced is even slower, which cannot meet the instantaneous demand for hot water
Applied to the heat pump hot water system, the heat pump inlet temperature is close to the hot water supply temperature, the heat pump is often operated at a higher hot water temperature, and the heat pump system has low operating efficiency

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples.

[0020] see figure 2 , is the system architecture diagram of the open hot water storage tank of the present invention. It can be seen from the figure that the system mainly includes:

[0021] Hot water storage tank 1;

[0022] The heat-insulating floating member 11 is arranged inside the hot water storage tank body 1, and the heat-insulating floating member 11 can not only move with the water surface, but also isolate the water surface from the air, so that the tank body 1 has a thermal stratification effect; In addition, a hot water supply temperature sensor 15 is arranged on the heat insulating floating part 11, and the temperature sensing part is in contact with the hot water and is close to the supply hot water inlet and outlet opening 124 of the flexible telescopic pipe fitting upper part 121 (near the heat insulating floating part 11 plac...

Abstract

The invention discloses an open type hot water tank, which comprises a hot water tank body, a heat insulation floating part, a flexible telescopic pipe, a hot water pipe group, a liquid level sensing device and a horizontal pipe, wherein the hot water tank body is provided with the heat insulation floating part capable of moving with water level and the flexible telescopic pipe; the upper part ofthe pipe is connected with the heat insulation floating part and is provided with a hot water circulation inlet and a hot water circulation outlet; and the heat insulation floating part insulates thewater surface from the air, so that the open type hot water tank has the layered-heat hot water supply effect of the closed type water tank and the hot water supply heat release efficiency of the hotwater tank is improved. In addition, the liquid level sensing device is arranged in the hot water tank, so the function of quickly heating and supplying hot water can be realized according to different hot water supply volume and temperature requirements.

Description

【Technical field】 [0001] The invention relates to an open heat storage tank, in particular to an open heat storage tank supplied with hot water by a heat pump or a heat recovery device. 【Background technique】 [0002] In the prior art, the hot water storage tanks of heating devices such as boilers or heat pumps generally have two types: closed and open. The closed water tank has heat stratification effect and high heat release efficiency, but it is a kind of pressure vessel, which must meet the relevant pressure. Container regulations require manufacturing and regular inspections every year. The manufacturing and maintenance costs are much higher than that of open hot water storage tanks. In addition, the amount of hot water supplied is equal to the amount of replenishment water. Partial heating and rapid hot water storage cannot be controlled. The open water tank has a simple structure and low cost. It is suitable for heat storage heating devices such as heat pumps and elec...
