When choosing a home air-conditioning system, heat pump air-conditioning and regular air-conditioning are two options that attract a lot of attention. They are significantly different in terms of working principle, energy efficiency, and applicable environment.

　　Working Principle:

　　Heat pump air-conditioning: heat pump air-conditioning adopts heat pump technology by extracting heat from indoor or outdoor and then transferring the heat energy through the heat pump circulation system. Therefore, it can not only cool in summer, but also provide heating function in winter.

　　Ordinary Air Conditioner: Ordinary air conditioners use a refrigeration cycle system that removes heat from the room by compressing refrigerant to achieve a cooling effect. Ordinary air conditioners usually only provide cooling service and require additional electric auxiliary heat to achieve heating in winter.

　　Energy efficiency performance:

　　Heat Pump Air Conditioner: Heat pump air conditioners are known for their efficient energy transfer method and are able to perform well in both heating and cooling modes. Compared to regular air conditioners, heat pump air conditioners are usually more energy efficient and can effectively reduce energy bills.

　　Ordinary air-conditioners: Ordinary air-conditioners usually perform better in cooling mode, but require additional electric heaters or other heating equipment for heating, and are therefore less energy efficient than heat pump air-conditioners.

　　Applicable environment:

　　Heat pump air-conditioners: heat pump air-conditioners are applicable in a wide range of environments and are capable of providing a comfortable indoor environment in different climatic conditions. However, in extreme cold environments, its heating effect may be affected to some extent.

　　Ordinary air-conditioners: ordinary air-conditioners are stable in terms of cooling, but they are relatively less adaptable in cold winters as they require additional heating equipment.

　　Initial investment and maintenance:

　　Heat pump air-conditioning: heat pump air-conditioning has a relatively high initial investment, but is able to pay for itself in the long run through savings in energy costs. However, maintenance and repair costs are high.

　　Ordinary air-conditioners: ordinary air-conditioners have a relatively low initial investment, but relatively high energy bills in long-term operation, especially in winter when additional heating equipment is required.

　　When choosing between heat pump air-conditioning and ordinary air-conditioning, you need to weigh up your needs and environmental conditions. Heat pump air-conditioners are suitable for households seeking year-round comfort and focusing on energy efficiency, while ordinary air-conditioners are suitable for areas with less use in cold winters or for users with limited initial investment. The final choice should take into account a number of factors such as economy, environmental protection and applicability to achieve a more desirable air-conditioning effect.

With the progress of science and technology and people's pursuit of quality of life, heat pump air conditioner has gradually become the first choice of modern family cooling and heating equipment. It has won the favour of the majority of consumers with its energy efficient, cooling and heating characteristics. However, there are many brands of heat pump air conditioners on the market with different functions, how to buy a heat pump air conditioner for yourself? Look at this one is enough!

　　First, understand the core technology

　　The core technology of the heat pump air conditioner determines its performance and effect. When choosing, you should pay attention to whether the air conditioner uses advanced heat pump technology, compressor and intelligent control system. These technologies will directly affect the cooling and heating effect of the air conditioner, energy efficiency ratio and service life.

　　Second, look at the energy label

　　Energy-efficiency labelling is an important standard for judging the energy efficiency of air conditioners. When choosing, you should give priority to choose the air conditioner with high energy efficiency level, which not only saves energy, but also reduces the electricity bill. At the same time, you also need to pay attention to the air conditioner's cooling capacity, heating capacity and other parameters to ensure that the air conditioner can meet the actual needs of the family.

　　Third, consider the comfort

　　In addition to the cooling and heating effect, the comfort of the air conditioner is also a factor to consider when buying. The noise level of the air conditioner, the precision of temperature control, and the way of air supply will affect the comfort of the use of the air conditioner.

　　Fourth, choose a big brand and quality service

　　Choosing a well-known brand ensures the quality of the product and the reliability of the service. Well-known brands usually have more mature technology and better service system, can provide users with more reliable products and better after-sales service. Understand the brand's after-sales service policy, including warranty period, maintenance outlets and after-sales service response speed, etc., to ensure that you can get timely and professional support in the process of use.

　　Therefore, when buying a heat pump air conditioner, you need to comprehensively consider a number of aspects such as core technology, energy efficiency labelling, comfort, brand awareness and quality service. Only in this way can you buy a heat pump air conditioner with excellent performance, high comfort and perfect after-sales service, and avoid stepping on the pit.

The density of cold water and hot water is not the same, the density of cold water will sink to the bottom, while the density of hot water is small will float on top, cold water comes in will not immediately mix the water.

Water temperature is cold and hot general situation is the problem of piping, it is recommended that you can directly release water from the tank hot water outlet to see if it is normal, after the pipeline will be cold and hot, that is, the pipeline of the water pipe, or mixing valve is bad, it is recommended to check the pipeline first. Can not judge can consult 400-647-9858 after-sales phone.

The factory setting is generally the default temperature of 55 ℃, but it is generally not recommended to adjust to 50 ℃, because a long period of high temperature operation, will affect the service life of the compressor.

Air water heater tank is pressurised, the pressure of the cold water and the flow of hot water released is proportional. Cold water pressure is large hot water out of small, may be the cold water inlet dirty blocked, you can disassemble the cold water inlet for cleaning. Or cold weather, cold water pipes are frozen, it is recommended to thaw the tank cold water pipes.

Commercial machine hot water out of small, may be the booster pump is not open or bad, there may be a valve or pipe dirty blockage.

If the bottom of the host leakage is a normal phenomenon, the machine work will produce condensate, condensate flow and temperature, humidity related, as long as the condensate pipe is connected.

Too much water pressure in the tank will make a rattling noise.

If the water pressure is high you can install a pressure reducing valve;

If it is the safety valve that makes the rattling sound is the safety valve is bad;

If the inner coil is loose, this is not repairable, you can only replace the water tank.

The host needs to be installed in a well-ventilated environment, no corrosive gases, liquids, dust, can be installed outdoors, wind, rain does not affect the heating effect of the machine itself.
