Description

Energy-saving-type dehumidifying air-conditioning system
Technical field
The present invention relates to a kind of air conditioner dehumidification equipment, is a kind of energy-saving-type dehumidifying air-conditioning system specifically.
Background technology
In summer, the cooling water temperature that feeds in the air conditioning chamber generally all is lower than the dew-point temperature of room air, is easy to cause indoor steam to condense.In order to prevent dewfall, all need dehumidifying in the air conditioning chamber.Domestic air conditioner does not have dehydrating unit, relies on the cold wind refrigeration, the indoor turbulent condition that is in, the indoor dewfall that is difficult for.But the evaporator coil place has with fixed attention, and water occurs, and generally is with a water pipe that its derivation is outdoor.The dehumidifying section is all arranged in the large-size air conditioning unit.General central air-conditioning is made up of new wind section, mixer, cooling section, dehumidifying section, pressurized segment.The cooling and dehumidifying air-conditioning system relies on handpiece Water Chilling Units to realize cooling and dehumidifying.The supply water temperature of handpiece Water Chilling Units is about 7 ℃, is lower than the dew-point temperature of air, makes processed water in air devaporation and dehumidifies.Cooling and dehumidifying is called surface cooling section in air-conditioning.The air-conditioning system of rotary wheel dehumidifying or liquid dehumidifying then is the humiture autonomous control system, and handpiece Water Chilling Units has only refrigerating function, and heating system provides the high temperature regeneration thermal source, supplies with the regeneration of runner or liquid and continues dehumidifying.The handpiece Water Chilling Units refrigeration is cooling section, and liquid or rotary wheel dehumidifying are the dehumidifying section.
In above-mentioned three kinds of dehumidification modes, the hot humidity load of cooling and dehumidifying is handled simultaneously, and form is the simplest, easy construction, but the restriction that is subjected to chilled water temperature can not reach lower humidity, and also surface cooler moves under wet cooling condition, breed bacteria and virus influence indoor air quality easily.In addition, handpiece Water Chilling Units need provide lower cold water temperature in this system, and therefore, the COP of unit is lower, and energy utilization rate is low.Have again, lower through the air themperature of cooling and dehumidifying, can not satisfy the human comfort requirement, also must heat and make its temperature rising, reach just can send into behind the indoor ventilation state point indoor.Solid drier dehumidification system and liquid drier dehumidification system separate processing to the dehumidifying of air with refrigeration.Rotary-type dehumidifier is adopted in the solid drier dehumidifying usually, utilizes the strong characteristics of salt wettability power such as porous material such as silica gel, active carbon, molecular sieve and lithium chloride crystal, and low water capacity is arrived in air-treatment.Air is approximately constant-enthalpy process in processing procedure.The temperature of new wind can rise to some extent.The liquid drier dehumidification system utilizes the strong moisture-absorption characteristics of the aqueous solution such as triethylene glycol, lithium chloride, calcium chloride and lithium bromide that air is dehumidified.New wind is approximately the isothermal processes process in processing procedure.In the two kinds of dehumidification process in back, humiture is independently controlled, handpiece Water Chilling Units is only born indoor sensible heat load, about 20 ℃ of supply water temperatures, compare with cooling and dehumidifying, unit COP is higher, the energy utilization rate height, and dehumidification process does not have dew-point temperature restriction, the water capacity of new wind can be handled very lowly, is good dehumidification mode.But must have the thermal source of high temperature that regeneration temperature is provided, dehumidifying just is able to back and forth.Therefore, these two kinds of dehumidification systems all have the special heat source system of a cover, and as solar energy system, geothermal system or gas burning system wait provides the running of the heat drive of higher temperature system.Though solar energy system and geothermal system have been utilized natural energy source, relatively environmental protection and energy-conservation, the systematic comparison complexity, initial cost is bigger.Gas burning system then operating cost is higher, and therefore, seeking suitable high temperature heat source is the key technology that realizes solid dehumidifying.And in the process of the high temperature energy of seeking to regenerate, people have but ignored the system self that is wasted and have produced this part heat.
Summary of the invention
Technical problem to be solved by this invention is to overcome the technological deficiency that prior art exists, and a kind of energy-saving-type dehumidifying air-conditioning system is provided.Indoor what not only need cold but also need to dehumidify, use the low-temperature loop heat pump to provide indoor refrigeration required refrigeration duty.The low-temperature loop condensation heat is as the thermal source of high temperature loop heat pump.The condensation heat of high temperature loop heat pump is as the required high temperature heat source of desiccant wheel adsorbent reactivation.
