1, when "Renewable Energy Law" promulgated? A: The "Renewable Energy Law" was officially implemented on January 1, 2006. Ground source heat pump system is one of the main ways to apply renewable energy and is also the most advantageous system form for combining with solar heating system. Source heat pump system engineering specifications "when promulgated? How to choose the right ground source heat pump system? A: "Ground Source Heat Pump System Engineering Specifications" (hereinafter referred to as the standard). The specification has been promulgated and came into effect on January 1, 2006. The current national standard "water source heat pump unit" GB / T19409, for different ground source heat pump system, the corresponding water source heat pump unit normal work cold (heat) source temperature range is also different, the design should be properly selected (as shown below). Cold / hot source for normal operation of water ring heat pump system Temperature range: 20-40 ° C (cooling) 15-30 ° C (heating) Groundwater heat pump system Normal working cold (heat) source Temperature range: 10-25 ° C ) 10 ~ 25 ℃ (heating) Ground heat pump system normal working cold (heat) source temperature range: 10 ~ 40 ℃ (cooling) -5 ~ 25 ℃ (heating) 3: What is the ground source heat pump system? A: The ground source heat pump system utilizes the relatively stable temperature of underground soil or groundwater at a relatively low temperature, and exchanges heat with the interior of a building by inputting a small amount of high-grade energy (such as electric energy), using a piping system or groundwater buried in the building, Achieve low-grade thermal energy to high-grade dual-use air-conditioning system. It consists of water circulation system, heat exchanger, ground source heat pump unit and control system. Ground source heat pump system instead of the boiler in winter to remove heat from the soil to the building about 30-40 ℃ hot air heating, summer instead of ordinary air conditioning to the soil heat, to 10-17 ℃ in the form of cold to the building cooling. 4, Why can the ground source heat pump system save money? A: GHP (ground source heat pump system abbreviation, the same below) can save money in terms of operating costs and maintenance costs. Compared with other systems, the initial investment can be tied within three years. There is a positive inflow of capital here because energy savings in the system often exceed mortgage payments. In addition, foreign and Taiwan governments also give certain discounts and rewards to customers who purchase GHPs. I believe China will implement this universal policy in the near future. On the one hand, efficient output power and input power ratio. The same building, you will save the next large additional operating costs; the other hand, "fool operation mode" of the operation and management. Save you the next big management and maintenance costs. The savings on both expenses will allow you to fully recover your initial investment in a fraction of the time. 5, how high the efficiency of ground source heat pump system? A: The most efficient GHP system for heating and cooling systems today offers 50% to 70% more heating efficiency than other heating systems and 20% more efficient cooling than air conditioners 40%. These saved energy is reflected directly on your bill. If health hot water (or free cooling that can be provided when heating hot water in the summer) is provided free of charge during summer cooling, user spending is less. 6, if it is a transformation project, my existing pipeline system can be used? A: Yes, most of the time it works. Your dealer or installer will determine the plumbing requirements and make minor changes if necessary. 7, ground source heat pump system high noise it? A: GHP is very quiet, providing a comfortable environment both inside and outside your home. GHP does not have outdoor fans, so it does not disturb outdoor activities or disturb adjacent yards. 8, ground source heat pump system safe? A: The GHP system is very safe. Since there is no exposed outdoor equipment, all the units have no direct external cooling fan, will not cause any harm to children. GHP No open flames, flammable materials and potentially dangerous fuel tanks. The heating of sanitary hot water is indirect and there is absolutely no question of using electric heaters or using gas water heaters to cause personal injury. Ground source heat pump unit with automatic "fool operation mode", the entire system to take five ultra-low, high pressure protection, ultra-low, ultra-high temperature protection and compressor unloading protection. 9, Why can the ground source heat pump system protect the environment? A: GHP is very friendly to the environment. It conserves natural resources by controlling climate effectively - and also reduces waste. The use of factory-sealed refrigerant minimizes damage to the ozone layer and requires little refilling of the refrigerant. For the residential environment, because there is no cooling tower and outdoor unit, the entire residential environment can be more beautifully planned. 10, the life of heat pump system is how much? A: GHP is very durable and reliable. The GHP consists of fewer mechanical components and all the components are buried underground or installed in the room to protect them from direct contact with external conditions. Underground pipelines have a 50-year life expectancy. FHP's ground-source heat pump unit life expectancy is 25 years.
