Description
Technical field
The utility model relates to energy-conservation and technical field of energy utilization, particularly a kind of Renovation of air-conditioning system method and apparatus being applied to air conditioning and heating industry.
Background technology
Current China Air Conditioning System pattern mainly contains several as follows: 1, single cold air-conditioner host joins cooling tower+boiler air-conditioning system; 2, all kinds heat pump type air conditioning system; 3, lithium bromide air-conditioning system; 4, ice conserve cold+other heat source air conditioning systems etc.Wherein, single cold air-conditioner host refrigeration, cooling tower heat radiation is utilized in summer, the advantage utilizing winter boiler to carry out the mode heated is that application mode is flexible, do not retrain by scale of the project, initial cost is low, can be widely used in all kinds of building, but equipment has the idle time period, whole efficiency is not high, boiler combustion fossil energy, and exhaust has pollution.All kinds of heat pump type air conditioning system comprises air source heat pump, water resource heat pump, earth source heat pump, sewage source heat pump etc.Wherein utilize outdoor air the simplest as the air source heat pump application of Cooling and Heat Source, its advantage is that summer in winter two Ji Jieke uses, initial cost is low, application mode is flexible, but unstable working condition, especially under season in summer in winter two least favorable environment, work limitation rate is lower, have frosting possibility winter, needing to carry out electric auxiliary heating can normally use.Water resource heat pump utilizes surface water and underground water as season in summer in winter two Cooling and Heat Source source, work safe and reliable to operation, year-round operation efficiency is high, but need have reliable and stable water source could use near building, current mining of groundwater use is restricted.The long-term stable working state of earth source heat pump, operating efficiency is higher, and project operation expense is low, but need early stage building site area large, carry out the process of well-digging pipe laying, project initial cost is high, large by geographical environment, geological condition constraints.Lithium bromide air-conditioning system utilizes heat energy as the energy of unit, can provide hot and cold water simultaneously, and it is little that it runs power consumption, and used heat can be utilized as the energy, but it requires that the project scale of construction is large, and year decay is more, and operating cost is higher, management inconvenience.Ice conserve cold utilize night at a low price electric power the form of cold by ice is stored, need daytime to discharge during cooling, its cryogenic temperature is low and stable, and air-conditioning effect is good, and economical operation is simple, but initial cost is higher, needs winter other thermals source to carry out heating.
Relatively above in the air conditioner cold-heat source of routine, due to its advantages, the application that single cold air-conditioner host joins cooling tower+boiler air-conditioning system is the most also widest in area.Great proportion is occupied in the large, medium and small air conditioning system of China.In summer, single cold air-conditioner host utilizes compressor the heat extraction of chilled water in custom system out to be transferred in cooling water the compression of cold-producing medium, to be dispersed in air by cooling tower again thus constantly for custom system provides cold, utilize winter boiler to supply water heating to custom system, thus provide thermal source for user's air-conditioning system.In Huaihe River areas to the south, China Qinling Mountains, all not central heatings in winter, single building or groups of building adopt central air conditioner system to carry out heat supply often.Adopt air-conditioning period in building, outdoor temperature is less lower than the time period of five degree, and boiler output is incomplete.In such a system, whole heating season all adopts boiler to carry out heat supply, and the efficiency of combustion of boiler is low, and required fossil energy is non-renewable energy resources, in the process of burning, include the material to environment such as sulfide, nitride in emission.The formation of the atmosphere pollution that annual winter causes due to the burning of various boiler and haze weather, causes great harm to human health.Therefore, winter, burning boiler directly caused environmental pollution and energy waste, and simultaneously, winter, singly cold air-conditioner host and cooling tower were stopped using, and caused the idleness of equipment.
In the winter time, clammy air still has uniform temperature, and for the environment that specific humidity air temperature is lower, this part clammy air is still an infinitely-great thermal source, can be absorbed the heat in air completely by certain way.Meanwhile, solar energy optical-thermal is a kind of heat energy of pollution-free, environment-friendly high-efficiency, and the strong solar energy in this air-conditioning system in period of winter solar illumination is not applied, and causes great energy waste.
Therefore, if single cold air-conditioner host and cooling tower are transformed, thus environment temperature joins cooling tower to absorb heat in air, to make full use of solar energy optical-thermal higher than utilizing single cooler in more than five degree time periods in the winter time, form a kind of round-the-clock solar air-conditioner system and air conditioning and heating is carried out to user, boiler service time can be greatly reduced.Make full use of solar energy to heat single cold air-conditioner host cooling backwater simultaneously, improve single cooler inflow temperature and then improve single cooler heating efficiency.Thus, the cold air-conditioner host of former idle list can be used as high efficiency heat supply main frame, make use of free of contamination regenerative resource simultaneously, a large amount of expense can be saved, reduce environmental pollution, have extremely important economic worth and social value.
