Description
Technical field
The present invention relates to adsorption and dehumidification constant temperature method and system thereof, particularly relate to one and middle warm water is provided, condensation heat during cooling tower compressor operating is whole or major part reclaims simultaneously, refrigeration control as the regeneration thermal source of low temperature moisture sorbing system is wet system, high temperature frozen water (10C-11C) is made the refrigerant of outer cooling simultaneously.
Background technology
At present, air dewetting mainly contains four kinds of modes, ventilation drying, cooling and dehumidifying, liquid desiccant dehumidifying and solid absorbent dehumidifying.In dehumidifying air-conditioning system, cooling and dehumidifying and solid absorbent dehumidifying are Main Means.Under the condition that cooling and dehumidifying is not very high (RH ≯ 60-70 %) to humidity requirement at environment, effect or relatively good, stable performance and energy consumption is also lower, current Application comparison is extensive.But in production environment to humidity requirement higher (RH≤45-60 %), or the place that humidity required precision is higher, adopt cooling and dehumidifying to be obviously just uneconomic.Adopt rotary dehumidifier, will not air impact be subject to, and moisture removal is large, under being specially adapted to low humidity conditions, if but all dehumidifying only adopts the rotary dehumidifier of solid adsorbant principle to carry out, because its regeneration energy consumption is also larger, this kind of scheme neither be most economical.
For this problem, more existing producers propose respective solution, Authorization Notice No. is the patent of CN 1129753C, provide a kind of desiccant assisted air conditioning apparatus to combine to increase work efficiency with heat absorption type heat pump assembly, but its shortcoming is, in order to cool required temperature, need the low-temperature cold water of 10-15 DEG C (evaporator refrigerant temperature is lower).When utilizing the heat extraction of cooling-water machine under this state, heat extraction can only be carried out according to this low-temperature cold water, therefore COP(coefficient of performance, coefficient of performance of refrigerating) not high.If certainly make cold water high temperature higher, just more can improve COP, but according to prevailing system cold water temperature because the temperature needed by dehumidifier has been immobilized, therefore, in this technical scheme, COP can not improve again.
Another Authorization Notice No. is the patent of CH101149203B, provides the equipment of temperature (15-30 DEG C) cold water in one.The sealed cooling tower of air cooling and cooling-water machine directly arrange, by loading the confession cooling-water machine of a set of unit, according to atmospheric temperature, design temperature carries out various running, compared with when providing cold water with common air cooling cooling-water machine, it is a kind of system that can reduce power consumption.When atmospheric temperature is than chilled water system inlet temperature height, water is by cooling tower, and water temperature rises and produces heat waste, therefore by bypass cooling-water machine individual operation, the defect of this technical scheme is, heat extraction during cooling-water machine running can be disposed in air in vain, cannot reclaim, cause waste.
Therefore, a kind of all features both having remained existing rotary dehumidifier and cooling tower are provided, make again the energy of two kinds of systems utilize each other, so reach best environmental protection, green, low-carbon (LC) and energy-saving effect the refrigeration control system that wets just seem particularly important.
