Technical barriers cooling tower systems analysis and application holds many lessons, civil air defense projects commonly used cooling tower water heat pump air conditioning system, based on quantitative circulating water cooling tower is halfway media, and outdoor air heat exchange purposes, through the heat pump technology, outdoor air low potential energy into high-potential energy for moisture dehumidification air defense projects, essentially attributable to air-source heat pump (System fatal weakness is the science of climate conditions, constraints, summer cooling rate increases with the outdoor air temperature and reduce , winter because the outdoor air temperature is too low to carry out heating, low group rates. using spring water source heat pump) system, the abolition of the cooling tower, through the heat pump works directly with the spring heat, to avoid the influence of atmospheric temperature, so that one machine and two use, energy efficient, not only can meet the dehumidifier in the summer issue of civil air defense projects, but also the introduction of ground projects to solve the mining warm winter and summer cooling ground engineering problems, with excellent application prospects. A technical demonstration of cooling tower water source heat pump air conditioning system, essentially attributable to air-source heat pump system. Air-source heat pump system, low potential energy from the outdoor air, the cooling conditions in the summer, heat pumps require a lower temperature air-cooled condenser media to heat outdoor air to pass to reach the goal of cooling, contentment cool. Heating in winter conditions, the heat pump requires a higher temperature air media, taking evaporator cooling capacity to achieve the goal of heating, heating contentment. However, the atmospheric temperature of seasonal changes in joy and law precisely value the contrary, in the summer the outdoor temperature is high, is not conducive to cooling condensers, cooling rate reduction and heat pump season expectations; winter outdoor air temperature is low, is not conducive to take evaporator cooling capacity, the system reduce heat rate and lower groups run rate, which is the air-source heat pump system insurmountable technical obstacle. Air defense projects is a closed underground space, heat pump systems can not directly heat with outdoor air, only to quantify circulating water as a medium, through the ground and outdoor air heat exchanger cooling tower, the implementation of cooling, dehumidification contentment. But because of the high summer outdoor air temperature, cooling tower circulating water quantitative temperature will rise, resulting in reduced heat pump cooling rate. Arrival of winter, even though the choice of water - water heat pump, heating can not be implemented, the huge limitations, so the cooling tower water source heat pump system technology can not overcome the stumbling block resolutely atmospheric temperature effects. The Earth is a huge body thermostat, spring bears endless energy. According to tests, 30 meters below the temperature stability of shallow perennial springs around 18 ℃, much higher than the winter outdoor air temperature, and the outdoor air temperature is much lower than in the summer, if the heat pump air conditioning system uses spring air defense projects as a low potential energy, it can overcome the stumbling block air source heat pump technology, which greatly increase the population rate of the system. In addition, in the summer, after the heat pump technology to lower the amount of cold spring water into a high cooling capacity, while the waste heat from air defense projects pass through the spring recharge technology; winter and after heat pump technology, the spring low heat into high heat, while After recharging technology to pass the cold spring, so, keep the cold winter with summer, keep the heat in summer and winter use, it has played an accumulator spring utility to protect perennial causative air conditioning system. Therefore, the spring-source heat pump system, low potential energy is taken from the springs, the temperature of the heat pump directly with perennial spring heat stability, are not affected by atmospheric temperature, overcoming the technical stumbling block air-source heat pump system, the implementation of one machine, saving investment, low overall running costs, have air-conditioning systems for air defense projects spring water resources Haobo region. Two examples of projects in Kaifeng City, a Accessorily Built civil air defense projects, the use of spring water source heat pump system, the abolition of the cooling tower to Haobo spring as a low potential energy directly with heat pump implemented energy exchange, the implementation of the summer cooling and winter heating, met effect. On the basis of geological exploration report, the project location, 0-3 meters of sand, soil Jasa 3-15 meters, 15-60 meters of sand, silt 60-90 meters, 90 meters to the sand below. Perennial springs bit negative 3 meters. Because the affected underground Yellow undercurrents, spring flows southeast from the northwest, water Hao Bo, water quality, easy as well, bears geothermal energy resources Hao Bo. Have the basic conditions for the use of spring water source heat pump system. The spring water source heat pump system works by circulating water pump host system and heat system composed of three parts. Based engineering heat and moisture load calculation, the host selection screw pump water - water heat pump, causative environmentally friendly refrigerant HFC-134a, work pressure is low, the summer maximum cooling capacity of 582KW, maximum braking heat for winter 634KW; circulating water system used two Taiwan head is 50 m vertical circulation pump, with a prepared one, cold water closed loop flow 77t / h, closed loop water flow 84t / h; a spring system design to wells, depth of 84 meters, hole diameter 0.3m, back two wells, depth of 76m, borehole diameter 0.3m, well spacing 20m, plugging and buried depth of 1 m, submersible pumps lift 50m, flow 46t / h. Spring water temperature 17.5 ℃. After testing, the cold water temperature cool in the summer conditions 7-12 ℃, winter heating water temperature conditions 47-56 ℃, temperature and relative humidity within the project meet the design requirements. 3 application advantages practice confirmed spring source heat pump system with cooling tower water source heat pump system dwarf, has the following application advantages: (1) The system cancels the cooling tower is conducive engineering protection, to ensure the normal operation of the air conditioning system of war, the population growth in engineering Protective efficacy.
