Some basic knowledge you need to know as a qualified air source heat pump distributor1. Essential common sense: national energy conservation policy
As the whole world attaches great importance to environmental protection, the governments of various countries have issued corresponding support policies to improve their own natural environment. The same is true in China. The government is increasingly promulgating energy-saving policies, and the production requirements of various enterprises are also getting higher and higher. Therefore, being familiar with the country’s new energy policy is very helpful for dealers to increase their sales confidence.
The use of air source water heaters is very common in some developed countries. Survey data shows that in Japan, the sales volume of air source water heaters has far exceeded that of electric water heaters. About 30% of the hot water equipment in the United States uses air source water heaters, and in Europe, Australia, New Zealand and other countries, air source water heaters are also included in the promotion of government financial subsidies. In China, with the continuous advancement of coal-to-electricity projects, governments at all levels have continuously increased policy support for the new energy industry. As an important part of the new energy industry, air source heat pumps are bound to usher in greater development opportunities.
2. Essential common sense: the characteristics of the air source heat pump
Since the air source heat pump absorbs the heat in the air, the temperature in the air has an impact on the energy saving effect of the heat pump water heater and the speed of hot water production. The energy efficiency of 1:3.8 mentioned above refers to the average energy efficiency for a year. When the temperature in the air is lower than 15°C, the hot water production speed will be relatively slow, and the energy efficiency ratio will decrease as the temperature in the air decreases; vice versa, when the temperature in the air continues to rise , The energy efficiency ratio will continue to rise. Agents must be aware of the water production rate and energy efficiency ratio of air source heat pumps at various air temperatures to avoid misleading.
An agent recommended a 1.5 HP machine with a 200L water tank when selling products. This is what he said to the client at the time: The water in this water tank is used for bathing for five people. After it is used up, the temperature of the hot water can be raised to 55 degrees within 95 minutes. When installing this air-element heat pump water heater, the weather was still relatively hot, which fully met the standards stated by the agent. With the slow coming of winter, users slowly feel that the water in the water tank can no longer wash 5 people, and they cannot raise the water temperature to 55 degrees in 95 minutes. The user called the manufacturer with questions and said that the machine was not working. Since the agent did not explain to the user these conditions during the winter use, the user firmly believed that the unit was abnormal and required a new one, which caused unnecessary losses to both the manufacturer and the agent. Therefore, when communicating with users, agents and distributors must pay attention to the use of air energy.
As a brand manufacturer, you will generally have a systematic product technical training for distributors, and will also give a detailed introduction to the characteristics of the product. Therefore, dealers must not blindly promise customers the unachievable functions to avoid customer misunderstanding.
3. Essential basic knowledge: working principle of air source heat pump
Hot water can be produced with air, and hot water can be obtained by using the heat in the air. Do you believe this? Many consumers are very mysterious! Therefore, as a distributor, you must be familiar with the energy-saving principles of air source heat pump water heaters, and use the simplest and popular metaphors to quickly popularize knowledge among customers.
Most of the heat produced by air source heat pump water heaters to produce domestic hot water comes from the air, but this product still needs electricity to be "assisted". When promoting this product, most customers will ask the same question: You said that the air source heat pump is energy-saving. Isn't it still using electricity? Electricity is needed to drive the machine. When the air source water heater heats water, the heat mainly comes from the air. There is a substance called refrigerant (commonly known as refrigerant) in the unit to absorb heat from the air to heat the cold water! The electricity used only allows the refrigerant to continuously circulate in the sealed system to absorb the heat in the air to heat the cold water. The heat ratio of the two is about 1:3.8, which means that the air source heat pump saves 3.8 times of electricity compared to the equipment that uses electricity alone to produce hot water. This is why it saves energy.
Consumers actually don't understand it very much, and simply explain it this way, that is, the heat emitted by the air conditioner is recycled and reused. Electric water heaters can save more than half of the electricity than electric water heaters. In fact, more emphasis on the safety of products is what ultimately impresses customers.
4. Essential common sense: reasonable configuration of heat pump
What size to wear and what size clothes to wear. The same is true for air source water heaters. How many people and what kind of temperature are equipped with power equipment.
Some agents and distributors in the air source heat pump industry, in order to seek higher profits, the configuration for users is unreasonable. There is a user who runs a small hotel in the Yangtze River Delta, and the daily water consumption is about 3 tons. An agent used a 3-hp machine with 3 tons of water. When it was installed, it was summer, the weather was relatively hot, and hot water could be supplied normally. When autumn slowly came, users felt that the working hours of the unit were getting longer and longer. In winter, 24 hours a day can no longer be supplied normally. There is hot water, which makes users regret it. But now the only solution is to install electric heating. In this case, the operating cost will be greatly increased, and the gain is not worth the loss. In places like Shanghai, Hunan and other places where the temperature is low in winter (the average temperature is around 5°C), it cannot be configured according to the ratio of 1:1. The normal configuration is about 1:0.6 to 0.8, which means that 5 tons of water will be used for the main engine. If the agents of air source heat pump water heaters are profit-seeking, it will only make users gradually lose confidence in the product of air source heat pump water heaters, triggering a vicious circle! According to this phenomenon, there must be strict guidance requirements for dealers, not to be greedy for immediate benefits and forget about long-term benefits. In the long run, the dealers will not only hurt the brand but also the development of the entire industry. Because consumers only think that this product is definitely not good.
5. Essential common sense: master the knowledge of electricity usage
An excellent distributor of air source heat pumps must be a person who understands basic electrician knowledge. Since air source water heaters use water and electricity at the same time, it is the minimum requirement to master the most basic knowledge of electricity use. Especially for commercial air source heat pump units, the electricity consumption of the entire site must be considered before certain countermeasures can be taken.
Air source heat pump water heaters use electricity to drive the main engine to work. The main engine can be divided into multiple models according to the heating capacity. The size of the main power cord used by each model is different. There is a problem with the line should be able to handle it. I once encountered a dealer of a certain brand because they didn't know much about electricity usage, and a 5-hp engineering machine had a leakage switch tripped. I was anxious to call the manufacturer's after-sales staff and asked to take a car to Hunan to help him repair the machine. But people are in Guangzhou, and it takes another day to get there by car. In fact, this is a very simple problem. Leakage tripping can be solved by the elimination method. The after-sales staff of the manufacturer teaches the dealer to remove the power supply of the compressor, fan, and circulating water pump of the main unit through the telephone. The result is still tripping. It means that this is not about the main engine. Then he asked him to remove the power supply of the water supply solenoid valve, water supply solenoid valve, and return water solenoid valve, and finally found that as long as the power supply of the water supply pump is removed, it will not trip. This proves that there is a problem in the makeup pump. As a result, the water pump was disassembled and found that there was a short circuit inside. If someone at the dealer has mastered these basic knowledge, he can quickly help the user solve the problem and save the time and travel expenses of the manufacturer. In this way, customers do not have to complain that the machine has a problem all at once, which affects their own business.
Once you have understood all the basic knowledge, the next step is to sell the air source heat pump!
