At present, in order to meet the comfort of life and save energy consumption, air source heat pump with floor heating and central air conditioning is becoming more and more popular in the HVAC industry. The functions of heating in winter and heating in summer can be realized through one system, and some areas can also realize uninterrupted domestic hot water 24 hours a day. Such a system for floor heating, air conditioning and floor heating is also called air energy heat pump dual supply and air energy Heat pump integrated system.
The working principle of air energy heat pump
Traditional floor heating and central air conditioning systems mainly use two separate systems, which do not interfere with each other. The air energy heat pump integrated system is different. A heat pump host provides the heating source for floor heating and the refrigeration source for central air conditioning (it can also provide the heating source for central air conditioning). In winter, the heat pump host absorbs the heat in the environment, transfers it to the circulating water of heat exchanger , and then transfers the heated circulating water to sub-water collector , and then distributes it to the floor heating coils of each room. , and then dissipate heat to achieve heating in winter; in summer, the heat pump host absorbs the cold energy in the environment, transfers it to the circulating water of the heat exchanger, and then transfers the cooled chilled water to the fan panel in each room In the tube , cold air is released to achieve cooling in summer.
How energy-saving is the air source heat pump?
The energy saving of air source heat pump is mainly reflected in winter heating. The air source heat pump utilizes frequency conversion technology, jet enthalpy increasing technology, and two-stage throttling intermediate jet technology. It only requires a small amount of electric energy to drive the compressor , and can transfer the heat in the outdoor air to the room exponentially. In this way, the indoor heating effect can be achieved without the need for electricity itself to generate more heat. Therefore, the energy consumption is reduced by at least 1/3 compared with traditional gas heating.
For example: a heating area of 100 square meters is heated under the same conditions, and the indoor temperature is set to 20°C. The monthly cost of using gas wall-mounted boiler for heating is roughly between 1,200-1,500 yuan, while using an air source heat pump for heating The monthly cost is roughly between 500-800 yuan.
In addition, although the cost of air-source heat pump refrigeration is similar to that of ordinary central air-conditioning refrigeration, the comfort of air-source heat pump refrigeration is much higher. The air outlet temperature of the fan coil of the air source heat pump is between 15°C and 20°C, and the outlet air temperature of the fan coil of the ordinary central air conditioner is between 7°C and 12°C. It can be seen that the outlet air temperature of the fan coil of the air source heat pump is higher. High, it will be softer, the human body will be less stimulated by cold, and it will have less impact on the humidity of the room. The probability of being blown out by the air conditioner and causing " air conditioning disease " is lower.
Is the technology of air source heat pump mature?
The air energy heat pump integrated system is not a brand-new technology, but adds a floor heating system based on the traditional water system central air conditioning. Water system central air conditioners are widely used around the world. Many world-class landmark buildings, shopping malls, five-star hotels, 5A-level office buildings, etc. are almost all using water system central air conditioners. They have been used for hundreds of years so far. It has a long history, and it can be seen that the technology is very mature.
Will the air source heat pump leak after being used for a long time?
air source heat pump adopts water circulation system , so the pipes for concealed construction are very strict. Not only will they be constructed in accordance with standards, but they will also be subjected to pressure maintenance tests and repeated inspections to ensure that there will be no hidden dangers of water leakage. Therefore, as long as the construction is carried out in accordance with standard procedures, the possibility of water leakage in the integrated air source heat pump system is extremely low. Of course, excluding the problem of water leakage due to defects in the equipment itself, the main reasons for water leakage are system installation problems and untimely maintenance. If these two points are grasped, the probability of water leakage will be even slimmer.
How to choose a good air energy heat pump system?
Although there are many categories of integrated air source heat pump systems, more users will choose mature brands and products to reduce the failure rate of equipment.In addition, how to choose a good integrated air source heat pump system requires a professional HVAC company to design the plan and a mature construction team to install it. This also reflects the principle of "three-point product, seven-point installation" for the installation of semi-finished equipment. . Therefore, if you want to install a good air source heat pump system, the key is to find a professional HVAC company. When choosing HVAC company, you should pay attention to: HVAC companies have a relatively long establishment time, and HVAC companies The company has professionalism and service awareness. The HVAC company has construction cases or construction sites that you can visit.
Summary
The air source heat pump integrated system combines the respective advantages of floor heating and central air conditioning, and has also made many technical improvements, so that the air source heat pump integrated system has the characteristics of comfort, energy saving, stability, safety, environmental protection, long life, With its wide range of applications and other features, users who are using it are full of praise for it, users who have not installed it are flocking to it, and users who are installing it are looking forward to it. The air source heat pump integrated system echoes the " coal-to-electricity " policy promoted by the country. Its large-scale use is conducive to the improvement of the environment. It is also the main direction of the development of new energy-saving and environmentally friendly equipment in the heating industry. Users who use it will also more and more.
