Kang Jing, a Nanjing floor heating expert with 16 heating experience, said that when winter came, consumers began to consider the winter heating plan. At present, there are many heating devices on the market, such as air conditioning, fire roasting and other traditional methods, or new heating methods such as plumbing and floor heating? Which heating method is more energy-saving and economical? Here, let's listen to the opinions of experts. New heating comfort and environmental protection HVAC is a new concept in the heating market in recent years. The so-called HVAC refers to the integrated system of indoor heating, refrigeration, ventilation and indoor air conditioning. Dong Zhongcheng, deputy director of China Heating Radiator Committee, said that with the continuous development of the heating market, the heating methods also showed a diversified development trend. In addition to the traditional air conditioning, toaster and central heating methods in the north, various new heating methods such as floor heating, gas heating (water heating) and ground source heat pump have also emerged. Compared with traditional heating methods, HVAC is more energy-saving, comfortable and environmentally friendly, although the initial investment is large. Taking floor heating as an example, in addition to high thermal efficiency and low heat loss, floor heating can also effectively save energy, make the indoor surface temperature uniform, and give people a good feeling of warming their feet and cooling their heads. At the same time, water heating is not easy to cause polluted air convection, and the indoor air is cleaner. The insiders believe that due to the high air humidity and the high proportion of citizens suffering from rheumatism and respiratory diseases in Chongqing, Chongqing is more suitable than the north to install water heating facilities to meet the heating demand. The installation is convenient, energy-saving and affordable. Although the new heating has many advantages, even in the same area, the development of the HVAC market in Chongqing lags far behind Chengdu and other cities. In the final analysis, it is because of the problem of consumption concept. For example, many people think it is expensive, worried about water leakage and inconvenient installation. "In fact, the HVAC system at home is not a luxury. At least two-thirds of Nanjing people have this spending power." The heating expert in Kang Jing, Nanjing calculated an account for us: if a house with a square meter of 100 is installed with three hanging air conditioners and 1 cabinet air conditioners, it will cost nearly 20,000 yuan. The total cost of any kind of water heating and floor heating system is only about 20,000 to 30,000 yuan, but at the same time, if a gas heating system is installed in the family, there is no need to install a water heater, and the temperature of the hot water provided by it is basically constant, so there will be no sudden cooling and sudden heating. At the same time, the monthly heating cost is more than 30% less than that of air conditioning. Nanjing Kang Jing heating experts said that, in fact, tenants who have been renovated can also install HVAC. HVAC products are not high-tech products, and the installation is not complicated. For example, a house with a square meter of 100 can be installed in about 5 days without destroying the original decoration. Choose HVAC. HVAC systems are mainly divided into three categories-radiator system, floor heating system and central air conditioning system. At present, many owners will consider which heating system to choose when decorating their new houses. According to experts, various systems have their own unique advantages and disadvantages. Consumers should choose the most suitable system according to their living conditions, family members and the requirements for heating speed. For families with old people and children, floor heating is more suitable in winter. "The floor heating temperature is uniform and comfortable, which saves energy when used all the time, and the room is clean and beautiful; If you are often away from home, intermittent heating and water heating are better. The radiator is flexible to start and stop heating, and it heats up and cools down quickly, but it takes up room space. " Experts believe that consumers can choose according to their living habits. Nanjing Kang Jing heating experts also introduced that different areas and different types of houses are suitable for different HVAC products, such as houses, villas and other rooms with higher floors are more suitable for floor heating, and apartments are more suitable for radiator heating. Of course, you can also choose mixed systems (such as living room floor heating and bedroom radiator). HVAC experts remind consumers that if you want to install the whole home heating system, you must contact the heating product service provider before construction and plan the laying and placement of heating equipment in advance. When consumers buy HVAC products, they can go to the Red Star Macalline Backstreet of Jiangbei Red Star, where many HVAC brands gather. Consumers must think carefully when choosing brands. Don't rush to place an order just because the price is cheap. It is necessary to examine history, qualifications, scale and reputation. There should be no shortage of invoices and contracts. If necessary, the manufacturer shall be invited to produce relevant test reports. Link how to choose HVAC floor heating system-heating speed is slow, suitable for families who need "continuous heating". If there are old people and children living in the house for a long time, and the house is high in height and large in area, it is recommended to install floor heating system or mixed system; The system is not only energy-saving and comfortable, but also can completely solve the domestic hot water supply. Radiator system-heating speed is faster, suitable for families that need "intermittent heating". If there is no one living at home during the day and heating is only needed at certain time periods such as night and weekend, it is recommended to use the radiator system. Generally, it only takes about half an hour for the radiator system to reach the set temperature, and the temperature control is flexible, so that each room can realize real independent temperature control. Its "radiator" is also an excellent item for drying clothes at home, especially baby diapers. Generally speaking, the floor heating system is only suitable for simultaneous installation during decoration. If the renovated room is equipped with floor heating, it may destroy the original decoration. Radiator system can also be installed in the renovated room, but it requires high design technology and construction difficulty. Central air conditioning system-central air conditioning is not as comfortable as the above two systems, and the use cost is relatively high. Therefore, the central air conditioning system is generally used in large shopping malls, hotels or high-end apartments, and is rarely used by ordinary families. Central air conditioning only needs to be synchronized with the basic decoration, which is not suitable for renovated houses.
