Pipe and tank insulation. The pipeline insulation includes the insulation of the circulation pipe and the hot water supply pipe and the return pipe. Water pipe insulation can use insulation cotton or polyurethane foam two. Small diameter pipes are usually insulated with insulation wool, and large pipes are insulated with polyurethane foam. When the ambient temperature is low, the temperature of the water is particularly severely reduced. If the water supply pipe is used as a water return system and the heat supply pipe and the return pipe are not insulated, the waste heat will be greatly increased and the energy efficiency ratio will be drastically reduced. Water tank insulation is equally important, and stainless steel insulation tanks will generally use polyurethane foam 5mm insulation layer, and then add a layer of stainless steel outside the insulation layer. This tank insulation effect is good.
In the engineering installation method will also affect the heat pump energy saving effect. From the use of different methods can be divided into all-weather water supply and regular water supply two modes: all-weather water is mainly used in hotels, hotels, hospitals and other places, regular water is mainly used in schools, factories and other places.
The timing water supply installation method is relatively simple. As long as the two tanks on the tank and the main unit are used for cycle heating, then the hot water is used up after a certain period of time, then the cold water is added again, and the heating is resumed. This installation method is very energy-efficient.
There are many installation methods for all-weather water supply, such as the use of direct-heating, circulating, large and small water tanks, and so on.
Direct heating means that hot water can be used directly after the cold water is heated by the main unit. The outlet temperature can reach 45-55°C. This principle is controlled by a throttling device to make up the amount of water, and the water flow cannot fill the entire heat exchanger. Therefore, the heat exchanger must be considered when the heat exchanger is to be made. Repeated debugging to select the most reasonable diameter and water way.
Cyclic heating type is the host to increase the temperature of the water in the tank by circulating heating. When the water in the tank is used in part, the water tank will be replenished and then recirculated and heated to the required temperature. This installation method is relatively simple. .
The size of the water tank mode means that the host first heats a small tank to a certain temperature, then supplies all the water from the small tank to the large tank, and then heats the small tank to make up the water, and continuously circulates until the large tank is filled with hot water. This approach is relatively complex in terms of control, but it does not appear that the mainframe is heated at a high temperature, such as cyclic heating. Therefore, the energy-saving effect is relatively high.
