Problems solved by technology

[0008] The first type of mixed water single water tank is relatively simple and the most widely used, but the hot water supply is small (especially when the water supply temperature is low), and the water temperature stability and energy efficiency ratio are poor.
Its main defect 1: use more than 1/3 of the hot water of the water tank volume in a short period of time, and the water temperature will drop rapidly
Main defect 2: low energy efficiency ratio, small heating capacity, high equipment configuration power, long-term operation of the equipment in a bad state of high condensation temperature, high condensation pressure, and large operating current
It is very common for the inlet water temperature to be 5-10°C in winter, and winter is when the operating load of the equipment is the largest and the working conditions are the worst. The working principle will seriously affect the use effect of heat pump equipment: increase power consumption, reduce heating capacity, reduce hot water supply, and the water temperature drops rapidly during use. This phenomenon is especially serious for air source heat pumps.
In winter, if the heat pump equipment of the mixed water type single water tank method needs to provide sufficient heating capacity, the only way is to use the following methods: first,

Embodiment 1

[0039] Embodiment 1: The specific structure and working process of the present invention on the circulating heat pump water heater:

[0040] Such as figure 1 The shown multi-chamber immiscible water insulation water tank includes an insulation box body 1, a cold water supply port 4, a hot water supply port 10 and a temperature probe arranged in the insulation box body 1. The inside of the insulation box body 1 is surrounded by a plurality of insulation The plate 2 is isolated into N cavities from the 1st to the Nth, and N is a natural number not less than 8; the water hole 3 of the first cavity is only connected with the second cavity, and the first cavity is equipped with a water outlet 5. The water outlet 5 is externally connected to the water outlet pipe 8, and the water outlet pipe 8 is connected with the water inlet of the external water pump 12; the water hole 3 of the Nth cavity is only connected with the N-1th cavity, and the Nth cavity is installed with a heat sink. ...

Embodiment 2

[0047]Embodiment 2: The specific structure and working process of the present invention on the heat pump water heater with a built-in heat exchanger in the water tank: the structure and working process of the water tank are basically the same as in Embodiment 1: the heat exchanger (condenser) is installed in the first to the second Between the M cavities, the water supply port is the M+1 cavity, the water outlet on the first cavity is connected to the water inlet of a small power pump, and the N and M cavities are respectively provided with two return ports and corresponding return pipes , 2 return pipes communicate with the water outlet of the water pump through a three-way solenoid valve. When heating, the three-way solenoid valve makes the second water return pipe conduct, the first water return pipe is closed, the water pump runs, the water body circulates between the first to the Mth cavities and heats up, when the outlet water temperature of the host reaches the set tempe...

Embodiment 3

[0048] Embodiment 3: The specific structure and working process of the present invention on the electric water heater: In addition to the cold water replenishment port of the M+1th cavity and the hot water supply port of the Nth main engine of the water tank, the first cavity on the water tank has one outlet Water outlet, the Nth cavity has a water return port, there is a small power water pump between the water outlet and the water return port, and the electric heating tube is between the 1st and Mth cavities. If electric heaters are installed in each cavity from the 1st cavity to the Mth cavity according to the volume ratio of the cavity, the second water return port is not provided, and the water pump does not run during heating, and the water body between the 1st to the Mth cavity When the average temperature reaches the temperature, the water pump will run and pump the heated water into the Nth cavity; the outlet water temperature of the water pump will drop to the set tem...

Abstract

The invention relates to a multiple-cavity heat preservation water tank free of water mixing. The multiple-cavity heat preservation water tank free of water mixing is characterized in that the inside of a tank body is divided by a plurality of separation plates or separation films into N hollow cavities, each hollow cavity is provided with water passing holes, the water passing holes of the first hollow cavity are communicated with the second hollow cavity, the Nth hollow cavity is provided with a hot water supply port, the water passing holes of the Nth hollow cavity are only communicated with the (N-1)th hollow cavity, the water passing holes of the other hollow cavities are respectively communicated with a former hollow cavity and a later hollow cavity, the inside of the water tank forms a through path, and in the through path, series connection is formed from the first hollow cavity to the Nth hollow cavity, and all the hollow cavities are communicated. The first hollow cavity is provided with a water outlet which is communicated with a water outlet of an external water pump through a water outlet pipe, the water tank is provided with at least one water return port which is communicated with the water outlet of the external water pump through a water return pipe, the Nth hollow cavity is provided with a water return port, one hollow cavity in the middle of the water tank is provided with a cold water supplementing port. The multiple-cavity heat preservation water tank free of water mixing can basically avoid the phenomenon of mixing of cold water and hot water, improves the energy efficiency ratio and the heating capacity of a system, guarantees the hot water supply and the stability of outlet water temperature, adopts a sectional heating method, reaches a required temperature rapidly, and reduces power of equipment configuration and the size of the water tank.

Description

technical field [0001] The invention relates to an insulated water tank used in a water storage type water heater (water heater), in particular to an insulated water storage tank with multiple cavities and non-mixed water. The main application scope is: various water storage water heaters, water heaters, especially various heat pump water heaters (water heaters), including air source, water source, and ground source heat pump water heaters. Background technique [0002] The hot water use of water heaters and water heaters generally has peak and trough periods. In order to reduce the power configuration and cost of the host equipment, most of them do not use instant heating, but use water storage. Therefore, heat preservation storage is used. water tank. [0003] Heat pump water heaters are currently the most energy-efficient among all types of water heaters. Compared with electric water heaters, they can save an average of 75% of electricity. Therefore, they are also the fa...
