Guangxi water source heat pump products have a promising market

Abstract: It is reported that at present, several large cities in Guangxi, such as Nanning, Guilin, Liuzhou, and Qinzhou, have enjoyed preferential policies for water-sourced heat pumps in the country for two years. The Guangxi government encourages the use of water-sourced heat pump products. Companies with water-source heat pump products are the most encouraged, and they get more convenience from this policy.

Li Zhe of the Guangxi office of the United States, Italy and Italy revealed that since the Guangxi government implemented a subsidy policy on water source heat pump projects two years ago, the use of water source-source heat pump systems in Guangxi has become more frequent than in the past. According to the person in charge of the McWay Guangxi office, McQuay was able to stand out in Guangxi in 2011, and the sales of water-source heat pump products helped a lot. In addition, Johnson Controls York, Yangtze, Maple Leaf, and other brands also contribute to the use of water source heat pump projects in the Guangxi market.

In the past two years, the Guangxi government's subsidy for water source heat pump projects has adopted a 35-yuan subsidy per square meter for ground-source heat pump and solar thermal-thermal coupling systems, and a subsidy per square meter for shallow geothermal cooling and heating systems. 50 yuan -70 yuan, and so on, showing that the subsidies are greater.

In addition, in order to ensure the completion of the energy-saving renovation of existing public buildings during the “12th Five-Year Plan” and save the target task of saving 160,000 tons of standard coal, in addition to the subsidy policy, the Guangxi government proposed to further promote the monitoring of the energy consumption of office buildings and large-scale public buildings of state agencies. Platform construction. By strengthening process management, improving service levels, expanding platform space, and strengthening application of results. At present, the Guangxi region has already used the Guangxi Building Energy Consumption Monitoring System as a platform, and has organized and implemented energy-saving renovation projects for more than 20 projects such as the Guangxi Construction Building, the Guangxi Construction Research and Design Institute Production and Office Building, the Guangxi Meteorological Building, and the Guangxi Hydropower Complex. All have achieved good economic and social benefits. According to relevant person surveys, as of the end of 2011, Guangxi completed a total of 88 building sub-item measurement plans and construction drawings design, and all passed the expert review, and has now completed 53 Guangxi national government office buildings and large-scale distribution in Nanning, Liuzhou and Qinzhou. The installation, commissioning and site acceptance of sub-item measurement equipment for public buildings have successfully achieved the collection, transmission and reception of energy consumption data. These measures set the conditions for the development of water source heat pumps.

In the past, industry sources stated that the water-source heat pump project is not suitable for the Guangxi market because of the high construction cost, difficulty in construction, and the existing engineering companies that have such a small amount of capacity. To be considered in the long-term, a 3- If the 5-year water-source heat pump system cannot work properly, the project will be subject to greater risks. In addition, the requirements for water and soil in the country are not very mature in this aspect. The number of professional companies is too small. Therefore, water source heat pump projects have long been difficult in Guangxi. However, as the current policy is gradually put in place, the technical level among manufacturers has been improved, and a series of problems have gradually been overcome in the past.

In addition, Li, general manager of the Guangxi office in the United States, Italy and Guangxi, said that Guangxi's climatic conditions are suitable for the use of water source heat pump products. Guangxi is rich in rainfall and groundwater. The soil is mainly rich in water, and the groundwater level is high. Therefore, it is a good heat source for heat pump and cold source for air conditioning. For example, the ground source heat pump hot water system can absorb heat in the winter and absorb the cooling capacity in the summer to provide users with heating, cooling and annual hot water supply. The ubiquitous water makes the heat transfer efficiency of the soil greatly improved. Even if the heat in a certain place is extracted too much, the moisture in the soil will quickly “supple” more heat from the adjacent soil. Therefore, with the same heat pump power, the depth of buried pipes in Guangxi can be reduced by more than half compared with the northern provinces, and the initial investment cost is greatly reduced. In addition, the water source heat pump has no fuel or coal-burning pollution, and it is extremely environmentally friendly, and it also caters to the actual energy-saving needs. What is most worth mentioning is that Guangxi has always had a habit of using geothermal heat water systems. The concept of customary consumption has existed for a long time, which will inevitably lead to the development of the market in the later period.
