The difference between the plate change and the sleeve heat exchange is divided from the heating method of living hot water. There are two main types of thermal and volumetric forms, namely thermal models and tubes. Two kinds.
First, the principle of heat transfer: the sleeve heat exchanger is the tube heat transfer, the living hot water sleeve is nestled in the main heat exchanger, and the hot water is prioritized by the pump. The water pump stops working when living in hot water is running, and the hot water is heated in a high temperature water in the main heat exchange. The board is switched through a plate heat exchanger to heat the electric fireplace manufacturer hot water, and the priority operation of the hot water is completed by the electric three-way valve. When there is a hot water demand, the electric three-way valve will be inside the main heat exchange. The high temperature water introduction plate is heated to heat the hot water.
Second, the technical contrast: 1. The comfort of the hot water is moderately uses the living hot water process. When the user temporarily tu off the production of hot water and opens in a short time, because the water in the main heat is not flow, the remaining heat of the main heat exchange A high temperature water will continue to heat the hot water in the casing. At this time, there will be a high temperature water when you open your hot water, causing hot water and extremely hot, or even bus. On-board heat exchange form can be completely avoided, and hot water is safe and comfortable.
2, fouling When heating, the high temperature water will continue to heat the hot water in the casing, resulting in high temperature fouling; when the use of hot water is used or temporarily closed, due to the water in the main heat, the main heat The heat of the heat exchanger and a high temperature water continue to heat the hot water in the sleeve, which will cause high temperature fouling. As the use time increases, scale is getting worse, affecting the use efficiency of wall-hung fuace, especially water quality. In a harder area, there is often blocked phenomenon. Water temperature is generally limited to 60 ° C or lower (the actual use of water temperature is 50 ° C below 50 ° C), and the disassembly and cleaning of the plate change is also very convenient for 60 ° C below 50 ° C. 3, life life When the use of hot water is used or temporarily closed, since the water in the main heat is not flowing, the waste heat of the main heat exchange cannot be taken away in time, causing local high temperature, affecting the service life. Plate changed heat transfer form When the water pump is latency after the end of life, it can effectively avoid local high temperatures. Third, the structure and price comparison: the casing machine has no electric three-way valve valve, there is no separate living hot water heat exchanger, so the structure and control are simple, the price is relatively cheap.
The board is exchanged due to increasing the living hot water plate replacement and electric three-way valve, and the inteal components are relatively large, the price is also expensive. The casing is generally referred to as an economical model, and the board is called a comfort model. Fourth, the product model comparison: the casing machine is easy to foul, and there will be overheating during the start and stop of the hot water. The heat exchanger is determined that the casing is impossible to do too much, the power of the casing machine Located 18,24kw, the current market is up to 28kW. The switch can effectively reduce the risk of fouling from the structure, design, function and use. Effectively avoid the overheating of the casing in the start-stop process, and the comfort of hygienic hot water is higher.
How to hang up electric wall hung fuace energy saving power saving electricity coupon electric wall hanging fuace how to hang up? Come to make a family heating. According to the function, the electrical walls can be divided into a single heater, heating bathing, heating bath solar three-purpose home electric shelling fuace. The heating fuace can be divided into two ways of pressure and pressure, the inteal structure of the pressure is a water pump integrated waterway expansion water tank heating body control element, and there is a pressure-free primary expansion water tank, and a water pump waterway heat control element.
How to hang up the electric wall - there are two types of heating the heating principle of the electric wall hung fuace. There are two kinds of heating fuaces. Different heating methods are different: one is the electrical energy adopted by the electric energy to heat energy, its heating principle is The electrical energy is converted into thermal energy by energizing the pure resistance of electric appliance, ie Q = I * V * t. When designing this device, the problem should be considered, and the electrical energy is converted into thermal energy as much as possible. The other is to use a high-frequency alteating magnetic field that makes it a molecule to generate high-speed random motion and collision, rubbing each other with a metal surface that needs to be heated and the heated medium in high frequency alteating vortex. Generate thermal energy. How to hang up electric wall - Compare the electric wall housing fuace and gas wall hang fuace usage, although compared, the cost of purchasing electric walls is lower than the gas wall mounting fuace, but the use of gas walls is comfortable, energy-saving and service life. It is better than the electric wall. From the long-term perspective, the cost of using the gas wall is lower than the cost of the electric wall. For example, a residential area is about 100 square meters of owners. He installed gas wall hanging fuace installations in the comfort of 100, mainly for heating and living hot water. China Electric Fireplace It took approximately 6,000 yuan to bought a very good imported gas wall. In the peak of heating, the owner's daily gas consumption is only about 10 square meters, and only 2000 yuan will be spent in a heating season.
If it is a choice of an electric heating fuace, the electricity consumed is far more than these. Electrical wall hung fuace energy saving power saving small coups 1. Power selection of electrical walls. The power of the wall-hung fuace is different. The power of the electric wall-hung fuace must match the size of the room. The power of the electric wall required for the heating area of the room is large, otherwise the temperature in the room cannot be supplied, the electric wall is hung Work all day does not reach the heating effect of the desired heating. If the power of the electric wall is too big, it will cause waste of resources, so it is a very important factor in the power choice of the electric wall. 2. Laying pipeline problem during installation, the pipeline is reasonable, reducing unnecessary curves and pipeline laying, then reducing the energy consumption of the electrical wall hanging fuace in invisible. 3. The warm effect of the building, the warmth of the building wall is very important, the wall insulation effect is good, the heat consumption is small, the electric wall is in line with small, naturally, the wall insulation effect is not so hot. From the wall, it has caused heat waste. 4. The location of the house, such as the same area of the building, the same area, but due to the difference, the preserved thermal energy is not the same, it is different, and it is not the same in the family of a household. The rooms in the yang and the mulberry surface are also different from the energy consumption during heating. 5. The renovation of the house is also an important factor. If the same building, the same location, if the glass used in the decoration is different, it is very large, the double glass insulation will be more than a single layer of glass. Good effect, then save a part of the thermal energy. 6. The heating of the surrounding neighbors, the neighbors around it will hear, the temperature around his home will be high, if the neighbors are not heating, then their own walls are heating, self-utilization The workload of the wall-mounted fuace is increasing.
