10 questions about waterless floor heating!For anhydrous floor heating, many dealers want to do but dare not do it, because anhydrous floor heating has higher requirements for construction and there are fewer applications in the market. In order to let more friends know about waterless floor heating, this article collects the 10 questions that everyone is most concerned about about waterless floor heating during the Q&A session of the air source heat pump business school. I hope to bring you some help.
① What is the working principle of waterless floor heating?
The waterless floor heating system is mainly composed of air source heat pump heat source machine + floor capillary coil + controller. Its working principle is that the compressor drives the refrigerant to do work, absorbs free heat energy in the air, and the high temperature refrigerant condenses and cools in the underground capillary coil, directly The heat is transferred to the floor, and then evenly distributed to the room through the floor surface to achieve heating.
As the temperature gradient gradually decreases from the sole of the foot to the head is formed indoors, it gives people a comfortable feeling of warming the feet and the head. Floor radiant heating conforms to the fitness theory of Chinese medicine for warming feet and keeping cool, and is a more comfortable heating method at present, and is also a symbol of modern life quality.
② What are the advantages of waterless floor heating?
Waterless floor heating utilizes low-grade energy in the air to convert it into high-grade energy actually needed. In addition to the advantages of conventional floor heating, such as comfort, safety, environmental protection, and energy saving, waterless floor heating has higher energy efficiency and faster heating speed.
Since the waterless floor heating is through the capillary copper tube, it condenses and releases heat at a time, and its heating speed is much faster than the conventional floor heating. It does not need to be turned on in advance, unlike the conventional floor heating that takes a long time to preheat. In addition, waterless floor heating also has the advantages of no scaling, simple system, and low failure rate.
③ What is the operating cost of waterless floor heating?
Compared with conventional dual heating, waterless floor heating can save energy by about 30%. It is mainly reflected in two aspects. One is because the ground capillary copper tube passes through the refrigerant to condense and exchange heat, while conventional floor heating uses water heat transfer to exchange heat. After the second heat exchange, waterless floor heating is more energy-efficient. .
The other is that there is no water pump for waterless floor heating and no water consumables, which can save energy in this respect. Taking 118 square meters of heating area as an example, in fact, the average daily cost of a heating season is about 12 yuan, or even lower. Generally, distributors will promise a month's heating cost less than 400 yuan.
④ Is it difficult to construct waterless floor heating?
The air source heat pump waterless floor heating adopts the fluorine system ground floor. Because there are no water components, only the copper pipes need to be welded, which is equivalent to multi-line connecting pipe welding. It is faster than conventional floor heating and the construction is simpler.
⑤ Is the laying of waterless floor heating copper pipes different from ordinary floor heating pipes?
The waterless floor heating uses capillary copper pipes with an outer diameter of Ø4. The length of the copper pipe is 16 meters. It is similar to the conventional floor heating method. Generally, parallel or double parallel laying methods are adopted.
⑥ Are there any restrictions on the heating area for waterless floor heating?
The copper pipe for waterless floor heating is generally a 1P host with 10 bundles of copper pipes, which is equivalent to a 10-way manifold. The diameter of each pipe is Ø4, and the length of each capillary copper pipe is 16 meters. At present, the host of waterless floor heating ranges from 1P to 5P. According to different regions, the largest 5P unit can guarantee a heating area of about 250 square meters.
⑦ Will the indoor temperature decrease when anhydrous floor heating is defrosted in winter?
Air source heat pumps will face the problem of defrosting. Whether it is a water system or a fluorine system, there will be certain fluctuations in temperature, but the floor heating itself is an energy storage system, and the reduction of indoor temperature is very limited. The host is equipped with an intelligent defrosting system, so the defrosting effect will be more accurate and fast.
⑧ Will there be a large amount of local heat concentration in the ground temperature of anhydrous floor heating?
The waterless floor heating system has a low and stable condensing condition, one-time condensation, combined with ground radiation, there is no local concentration of large amounts of heat, and it perfectly meets the human body temperature demand curve.
⑨ Will the non-aqueous floor heating and refrigerant leak, and is it harmful to health?
Users do not have to worry about refrigerant leakage. First of all, the R410a environmentally friendly refrigerant used in waterless floor heating will be more secure in terms of safety. Secondly, during the construction process, the copper pipe laid is a complete copper pipe, which must be leak-checked before leaving the factory, and after the copper pipe is laid, there will be a systematic pressure-holding process. Detection. The only possible leakage is in the welding port, and the welding port will always be in the state of pressure holding detection before fluorine injection to ensure safety.
⑩ How long can the waterless floor heating last?
Anhydrous floor heating can be used at an ambient temperature of -25℃ (the lowest ambient temperature of a 5P machine can be -30℃); the service life of the host is generally 20 years; because the ground is a closed system, the service life of the copper pipe is 50 More than years.
