Ground source heat pump central air conditioning system is the use of shallow underground heat resources (also known as heat), through a small amount of high energy (such as electricity), the low temperature can be transferred to high temperature to achieve both heating and cooling Energy efficient system. Compared with the traditional gas or electricity-consuming air conditioners, it has the advantages of high thermal efficiency, small pipe occupancy space and high-rise building without multi-stage pressure tank. This approach is a trend in large cities in our country. It has the following features: First, Energy-efficient and efficient Source-source heat pump (ACHP) systems provide 70 units of energy at 100 units of energy, 30% at electricity, and "carry" the heat from the soil into the room. Compared with the boiler (electricity, fuel) heating system, the boiler heating can only convert more than 90% of the electric energy or 70-90% of the fuel's internal energy into heat for the users to use, and the ground source heat pump air conditioning system has the highest conversion efficiency Up to 4.7, so it can save more than two-thirds of electric energy than electric boiler heating, save more than half energy than fuel boilers, and the operating cost is 30-70% of all kinds of heating equipment; as the temperature of the soil is all Year is relatively stable, generally between 10 ℃ -20 ℃, the heating, cooling coefficient up to 4.3-5.8, with the traditional air-source heat pump (home window and split air conditioners, the central air-cooled heat pump) To be higher than 40%, its operating costs are only 50-60% of ordinary central air conditioning. Thermostat for heat pump unit thermostat control, according to indoor personnel changes and outdoor direct sunlight and other load changes to control the unit start and stop, the indoor temperature is always constant in the set temperature range, both to achieve cooling or heating The comfort effect can avoid the waste of energy and optimize the coordination of the energy utilization and the comfort of the indoor environment. This not only saves operating costs, but also easy to stratify, zoning control, measurement, in order to achieve maximum energy savings. two. Comfortably source heat pump air conditioning system, air conditioning system air evenly, the temperature distribution is reasonable, the air velocity is less than 0.3 m / s, no sense of hair. Small noise, noise reduction measures can be taken less than 40 dB. The cooling mode and the heating mode can be switched at any time, and the indoor temperature can be set within a certain design range according to personal feelings. three. Save space in building for easy operation and management No cooling tower and other outdoor equipment, eliminating the need for valuable area occupied by boiler room, cooling tower and affiliated coal yard and slag yard, avoiding the problem of centralized land occupation by traditional central air conditioning, saving space and land , Generating additional economic benefits and improving the external image of the environment. The indoor system is a decentralized system. Therefore, the height of the cross section of the main air duct in each area is small, which does not occupy the ceiling space in the building as much as the traditional air-conditioning system so as to ensure the use space of each floor. Heat pump units, reliable, no large-scale centralized units, without special duty, greatly reducing maintenance and maintenance costs. Unit can be achieved independent billing, household metering, to facilitate the owners of the entire system of management. four. Green, Environment-friendly and Non-polluting Ground-source heat pump air-conditioners do not need boilers and emit products of combustion when heating in winter. They can greatly reduce greenhouse gas emissions and protect the environment as well as comply with the UNFCCC. According to the report provided by the American Association of Geothermal Pumps, only the Scottish Kentucky, a total construction area of ​​158,000 square meters of Gothehhaus Hotel Ground Source Heat Pump System, annual emission reduction of 849 tons of CO2; SO2 19.97 tons; NO2 14.98 tons Dust 2.49 tons. When cooling in summer, heat is also transferred to the ground and no gas is released into the atmosphere. If widely used, it will greatly reduce the greenhouse effect and slow down the process of global warming. Fives. Low operating costs Ground source heat pump air conditioning system, energy-efficient features that determine its low operating costs. Very little maintenance, life and building over the same period, depreciation and maintenance costs are also much lower than the traditional air conditioning. High degree of automation, without professional control. Ground source heat pump air conditioning system heating and cooling costs only equivalent to the ordinary air conditioning system heating and cooling costs 30-70%. six. The application of flexible, safe and reliable, versatile source heat pump air conditioning system flexibility, can be used for new construction or expansion, reconstruction project, can be gradually phased construction. Heat pump unit can be flexibly placed anywhere, saving space. At the same time, ground-source heat pump without coal storage, storage tanks and other health and safety hazards. Ground source heat pump air conditioning system from the cold area to the tropical areas are applicable. For office buildings, hotels, hospitals, restaurants, shops, supermarkets, kindergartens, villas, residential quarters and other buildings to provide dual-use air conditioning system, and can provide hot water at the same time.
1. Description
Naipu G series Gravel and sand slurry pump is
designed specifically for continuous pumping of extremely aggressive
slurries, with a wide particle size distribution. Capable of handling
large particles at consistently high efficiencies results in low cost of
ownership. The large volume internal profile of the casing reduces
associated velocities further increasing component life.
