CN202133025U - Heating hot-water system with heat accumulating type domestic electric water heater - Google Patents

The utility model discloses a heating hot-water system with a heat accumulating type domestic electric water heater. The heating hot-water system comprises the heat accumulating type domestic water heater, wherein a hot water outlet and a cold water inlet are respectively formed on the side wall of the heat accumulating type domestic water heater; an electric heating rod is arranged at the upper part of the inner chamber of the heat accumulating type domestic water heater; the hot water outlet and the cold water inlet are respectively communicated with an upper layer hot water distributor and a lower layer return water distributor; the other ends of the hot water outlet and the cold water inlet are respectively connected with radiators; the cold water inlet is also connected with a tap water inlet; and a bathing hot water outlet is formed at the top of the heat accumulating type domestic water heater. When working under the lowest power, the heating hot-water system supplies hot water and heating for domestic consumers, has a good thermal insulation effect, and achieves temperature drop less than 1 DEG C within 15 hours.

Heat accumulating type household electrical hot water stove hot-water central heating system

Technical field

The utility model relates to domestic heating hot-water heating system field, specifically belongs to a kind of hot-water central heating system that utilizes heat accumulating type household electrical hot water stove.

Background technology

Boilers heated electrically is that electric energy is converted into heat energy; Being heated to the hot water of pressure or a kind of heat power equipment of swallow vapour (saturated swallow vapour) to water. it need not burner hearth, flue and chimney; Also need not the place of storage of fuels, greatly reduced the pollution that conventional suspicion coal burning boiler brings.In private residence, villa, minimized office place, need often to use hot-water central heating system, if can combine, utilize the heat of boilers heated electrically will produce a lot of energy-conservation effects with boilers heated electrically.

The utility model content

The purpose of the utility model provides a kind of heat accumulating type household electrical hot water stove hot-water central heating system, when the electric power low ebb moves, to the domestic consumer hot water and heat supply is provided, high insulating effect, and 15 hours temperature drops are less than in 1 ℃.

The technical scheme of the utility model is following:

Heat accumulating type household electrical hot water stove hot-water central heating system; Include the heat accumulating type back boiler; Be respectively equipped with hot water outlet, cooling water inlet on the sidewall of heat accumulating type back boiler; Heat accumulating type domestic hot water furnace chamber top is provided with electrically heated rod, and hot water outlet, cooling water inlet are communicated with upper strata hot water water-locator, lower floor's backwater water-locator respectively, and the other end of hot water outlet, cooling water inlet is connected respectively to radiator; Cooling water inlet also is connected with running water inlet, and the top of heat accumulating type back boiler is provided with the bath hot water outlet.

Being connected between described hot water outlet and the radiator is provided with frequency conversion constant temperature water pump in the pipeline.

The beneficial effect of the utility model is following:

(1) utilize high-temperature water density little, the principle that water at low temperature density is big at upper and lower each cloth one deck water-locator, makes hot water all the time in the above, and cold water makes full use of the capacity of hot water storage tank below.

(2) water outlet variable frequency pump according to return water temperature (can set, as 40 ℃), is regulated the rotating speed speed automatically, guarantees the indoor heating effect.

(3) when night dip period accumulation of heat, electric heating tube starts heating, and the control system is according to payload, automatically start-stop electrothermal tube group number.Electrical power is greater than heating load power, Yi Bian keep the heating requirement, Yi Bian heating water tank water makes temperature reach the temperature (can establish, as 85 ℃) of setting.

(4) peak period by day, electric heating tube stops heating, leans on the hot water that water tank held, and is the heat supply on daytime.The backwater Yin Wendu of system is low, and density is big, flows out through water-locator, reduces the turbulent flow of water, in the lower floor of equipment.Passing in time, the cold water layer raises gradually.During to low-valley interval, cold water pushes up near water tank.The hot water storage tank volume size disposes according to the room heating area.

(5) open the running water inlet valve, hot water goes out hot water from the top, and the user is provided hot water.
