Detailed ways

As shown in Figures 1 to 3, a multifunctional thermal insulation water tank includes a tank body 1, a water inlet 2 and a water outlet 3 are arranged on the tank body 1, and at least two sets of independent replacement parts are arranged in the tank body 1. As for the heat coils, the two ports of each heat exchange coil extend out of the box body 1 .

There are three sets of heat exchange coils, of which there are two hot water heat exchange coils, namely hot water heat exchange coil 7 and hot water heat exchange coil 10, and the other is a refrigerant heat exchange coil, and the refrigerant The heat exchange coil includes the upper section 5 of the refrigerant heat exchange coil and the lower section 6 of the refrigerant heat exchange coil at a certain distance, the two are connected by a connecting straight pipe 8, and an electric heater is also provided on the box body 1. Opening 4; three heat exchange coils are fixedly connected with box body 1 through fixed steel rope 9.

The refrigerant heat exchange coil is divided into two sets of coils, which are respectively located at the upper part and the lower part of the box body 1. The high-temperature and high-pressure refrigerant liquid coming out of the air source heat pump water heater passes through the upper part of the refrigerant heat exchange coil 5, and the refrigerant heat exchange coil The lower section 6 returns to the air source heat pump water heater. The refrigerant fully exchanges heat with the water in the tank 1 and warms it. The reason why the refrigerant circuit uses two sets of coils is to increase the heat transfer area and make the The heat exchange is more complete; at the same time, the water temperature in the tank 1 shows a gradually decreasing stratification trend from top to bottom, and the temperature difference between the highest water temperature and the lowest water temperature can reach about 20°C. Such a temperature distribution makes the condensation pressure not too high. If it is too high, the water temperature at a suitable temperature can be obtained, which greatly guarantees the reliability of the air source heat pump water heater.

The heat exchange coil 10 can be directly connected to the urban water supply system. The water used for daily life enters the heat exchange coil and is reheated by the water in the tank 1, which is finally about 5°C lower than the highest water temperature in the tank. The reason why the circulating domestic water loop enters from the lower part of the tank 1 and then comes out from the upper part is that in view of the stratification of the water temperature in the tank 1, the water with a lower temperature enters the lower water first. The lower part of the box body 1, after heat exchange, comes out from the upper part with a higher water temperature to obtain outlet water at a suitable temperature. This arrangement not only enables the circulating water to exchange heat evenly and fully, and increases the temperature of the outlet water in the shortest time, but also differs from the direct The water in the tank 1 can be used to obtain clean and hygienic domestic water, and the domestic water is completely isolated from live equipment, making it safer and more reliable for users to use.

The heat exchange coil 7 can be connected with the solar heat exchange circuit. In the sunny season, the water in the box 1 can be heated through the set of coils. Since the set of heat exchange tubes is located in the lower part of the box 1, it is mainly for heating The water in the lower temperature part of the tank 1 can accelerate the speed of water temperature rise and achieve the purpose of more energy saving. The set of coils can be selected according to the specific usage of the customer. Whether it needs to be increased.

The electric heating reserved opening 4 on the box body 1 can be used for the electric heating function, and is respectively located in the middle upper part and the middle lower part of the box body 1. The user can choose to open one or two electric heating systems according to the difference in outdoor ambient temperature to ensure It can provide hot water normally under the harsh environment of low temperature.

In addition to being used as the domestic water circuit in the secondary heating heat exchange coil 10, the water in the tank 1 can be used with air-conditioning terminal equipment such as fan coil units or floor heat exchange systems or other heating exchange systems in view of the phenomenon of water temperature stratification. The heating equipment is connected and used to achieve the heating purpose of heat exchange with the indoor air; the water in the middle of the box body 1 enters the indoor heating heat exchange equipment through the water outlet 3 on the upper part, and after heat exchange, the returned water with a lower temperature passes through the water inlet 2 Returning to the tank 1, the water at the water outlet 3 is located in the middle and upper part of the tank 1, where the water temperature is lower than the highest water temperature in the tank 1 and the outlet temperature of the domestic water. It is used as water for indoor heating and heat exchange, which can make the user feel To the cozy warmth of the space.

This embodiment has the following advantages:

1. The cabinet 1 or the heat exchange coil inside it can be connected with the floor heat exchange system, air conditioning and heating system, water heater, etc., so that the insulation cabinet has more functions and wider applicability;

2. When the heat exchange coil is connected to the water heater, the hot water in the tank 1 will not enter the water heater, that is, the water heater can have its relatively independent pipe network, which can better avoid water pollution of the water heater and make it more hygienic to use;

3. The refrigerant heat exchange coil has two sections. When the refrigerant is passed into the heat exchange coil, the water temperature in the box 1 can be distributed in steps. When the heat preservation box 1 is connected to the heat pump water heater, it can make Heat pump water heaters are more reliable in operation and can obtain suitable water temperature;

3. Realized the energy-saving effect of air source heat pump water heater which can save 3/4 of electricity compared with ordinary electric water heater. In sunny season, when used with solar heat exchange system, the energy-saving effect is better.
