Description
Technical field
The present invention relates to a kind of energy-saving fresh unit that can be realized aerial temperature and humidity and accurately control, belong to air adjustment
System design and manufacturing technology field.
Background technology
In all kinds of buildings, for meeting that the energy consumption of air-conditioning system of indoor thermal comfort environment of rural accounts for building total energy consumption
50% or so, the energy consumption level of air-conditioning system is to weigh a certain important indicator built and whether reach energy conservation standard.It is but current
The air-conditioning system generally used consumes substantial amounts of electric energy and made due to its own structure and in the defects of air-treatment mode
Into more serious problem of environmental pollution, thus the air-conditioning system for developing energy-conserving and environment-protective seems urgent all the more and anticipated with actual
Justice.
At present, the Fresh air handling units processing fresh air sensible heat load used in air conditioning system and latent heat load all pass through
Surface cooler is cooled down and dehumidification by condensation, is then sent into the fresh air of cool drying indoor.In order to reach this purpose, surface cooler
The temperature of middle low-temperature receiver allows for meeting fresh air sensible heat, the requirement of latent heat load processing simultaneously, but meets that sensible heat load is handled
It is required that sink temperature significantly larger than to meet the sink temperature of latent heat load processing requirement.Under summer typical condition, fresh air
Sensible heat load accounts for 60%~80%, and account for the total load sensible heat load of more than half originally can be handled using high temperature low-temperature receiver,
And low temperature cold source is shared together with latent heat load under existing air-treatment mode, cause in using energy source grade
Significant wastage；Accompanying problem is that too low sink temperature will cause the too low air temperature after dehumidifying, it is impossible to meet room
Between the requirement blown, now air is heat-treated again again, the energy resource consumption of air-conditioning system can further increase.

Fresh air after temperature height and processing is without reheating, so unit energy-saving effect is notable.But obtained in Practical Project at present
Into the heat pump driven solution dehumidifying fresh air handling group used, solution needs to be exchanged heat with refrigerant in some equipment, such as
Evaporator and condenser.But due to conventional dehumidification solution (such as lithium bromide and lithium chloride solution) to common metal with very strong
Corrosivity, so the heat exchange pipeline in equipment can not use copper or stainless steel material, removed in existing heat pump driven solution
The solution of evaporator and condenser in wet Fresh air handling units and the heat exchanging part of refrigerant are often using the titanium of rotproofness
Material.But titanium material is expensive for conventional metal material, this just considerably increases the manufacturing cost of Fresh air handling units.
And on the other hand, using solution and refrigerant progress direct heat transfer evaporator and condenser in often operating pressure it is larger, lead
Refrigerant is caused easily to reveal so that unit service behaviour is unstable.
In summary, to existing traditional Fresh air handling units and heat pump driven solution dehumidification unit is transformed and performance is excellent
Change is significant for the energy consumption and equipment cost for reducing air conditioning system.
