Background technology
The relative humidity that people are comfortable on air is 35%~65%, and many subtropical zone annual phases in the world It is more than that the high relative humidity of 70%, especially summer temperature often exceeds 80% and feels muggy and oppressive to humidity.Subtropical zone high temperature High humidity weather causes annual spring to have " the going back to Nan Tian " of long period, and indoor moisture regain causes furniture clothing mouldy, is generated in air A large amount of moulds and unpleasant peculiar smell, seriously affect the health of the mankind.
" going back to Nan Tian " at present prevents the method to get damp again:
One is dehumidified using air conditioner dehumidification pattern, and air-conditioning freezing damping causes indoor temperature to further decrease, and The highly humid air that outdoor is got in is easier to condense, and effect on moisture extraction is not notable and high energy consumption.
Secondly, using rotary dehumidifier heating indoor air dehumidify, work well but energy consumption be higher.
Thirdly, dehumidified using indoor cooled dehumidifier unit, with obvious effects but energy consumption is higher.
Above-mentioned three kinds of methods are all indoor air circulation dehumidification mode, cannot meet indoor fresh air demand.

When operation of heat pump, by the operation of fresh-air fan, exhaust fan and compressor, it is powered by four-way valve and triple valve Commutation does not commutate with power-off, and by the combination opened and closed with power-off that is powered in 1# solenoid valves, 2# solenoid valves, heat pump realizes system Heat or refrigeration and heating or the operation of refrigeration and three refrigerant difference flows of backheat, make to heat surface cooler, fresh air by fresh air Freeze the fresh air of surface cooler and fresh air backheat surface cooler, is freezed, heated, backheat and ventilation process.Meanwhile heat pump refrigerant system Refrigerant unite in different three different flows flowings, fresh air heat surface cooler, fresh air refrigerating surface cooler, fresh air backheat surface cooler with It is not involved in refrigerant in heat exchange surface cooler in the cold and hot surface cooler of air draft to be always connected to gaseous state low-pressure end, to ensure to participate in heat transfer sheet The refrigerant flowing that is circulated in cooler is steady, does not generate hydrops and pressure oscillation.
Equipment is by being arranged humiture transducer outer indoors, according to the variation of indoor and outdoor temperature and humidity, to 1# electricity Magnet valve, 2# solenoid valves, four-way valve, triple valve, fresh-air fan, exhaust fan, fresh air preheating device break-make different from compressor output Signal, load combinations obtain different operation processes;Equipment is equipped with fresh air preheating device and operation of heat pump fresh air heating process, heat Pump operation fresh air heats process, operation of heat pump fresh air refrigerating heating process, ventilation process, operation of heat pump fresh air refrigerating backheat work The different load combinations operation of sequence, standby process six.
Process one, fresh air preheating device and the heating of operation of heat pump fresh air
It is run when low temperature outside winter room:The process fresh air preheating device is run simultaneously with heat pump, and fresh air preheating device is to outdoor empty Gas is preheated, and supplement heat pump heating is inadequate, prevents air filter ice and snow from blocking, and avoids fresh air heating temperature too low and cold wind Discomfort, ensure that room air is fresh and the comfort of new air temperature.The design of fresh air outlet temperature is at 20 DEG C or more, fresh air Air near exit meets the requirement of Smaller load partial air conditioning heating, while being run for a long time by equipment, indoor whole Temperature can also rise 1~2 DEG C, reduce the heating load of entire room conditioning.
Process two, the heating of operation of heat pump fresh air
When winter outdoor temperature is higher and relative humidity is relatively low or when spring and autumn outdoor temperature is relatively low and relative humidity is relatively low Operation:Process effect is close with process one, but because outside air temperature increases, while heat pump efficiency increases with heating capacity, Therefore cancels the operation of fresh air preheating device and reduce electricity consumption.Since heat pump heating capacity is more than 15% or more refrigerating capacity, the temperature of fresh air Generally can be 10 DEG C higher than the temperature of room air or more, new air temperature is pleasant for indoor people, and can be full The requirement of sufficient Smaller load partial air conditioning heating, while the thermic load of entire room conditioning is also reduced, or it is indoor without additionally making Use air-conditioning heating.
Process three, the heating of operation of heat pump fresh air refrigerating
When winter end and spring and autumn outdoor temperature are relatively low and relative humidity is higher or outdoor temperature is moderate but indoor/outdoor temperature-difference compared with It is run when greatly or outdoor temperature is moderate but relative humidity is higher:The process first freezes to fresh air to be heated afterwards, i.e., first dehumidifies to fresh air After heat, ensure that room air is fresh, comfort of temperature and humidity, ensure room air drying, eliminate the outer humidity in spring room The adverse effect of air prevents indoor generation mould.
Since new air temperature is higher relatively low with humidity, it can give people warmer feeling, space near fresh air export direction Air, moreover it is possible to meet the requirement of Smaller load part cooling/heating air conditioner, while also reducing the heating load of entire room conditioning.
In addition, since compressor uses the anti-defrosting technology of return-air increasing enthalpy, compressor is in 5 DEG C of outdoor temperature, fresh air system Cold surface cooler refrigerated dehumidification will not frosting, ensure that room air is relatively dry, it is relatively low to solve conventional dehumidification machine temperature, because The problem of surface cooler frosting cannot dehumidify, conventional dehumidification machine operating temperature is at 15 DEG C or more.
Process four, ventilation
When spring and autumn outdoor temperature is moderate, relative humidity is moderate and indoor/outdoor temperature-difference is little or early summer and autumn end outdoor temp It is run when degree is not high, relative humidity is moderate and indoor/outdoor temperature-difference is little:Outside air temperature and humidity are all in comfort model at this time It encloses, fresh air only needs filtration treatment, which only has fresh-air fan operation.
The process also can independent operating, be mainly used for when equipment break down and fresh-air fan it is normal when, user may be selected Fresh air supply way runs forced ventilation, ensures the demand of equipment indoor fresh air before repair.
Process five, operation of heat pump fresh air refrigerating backheat
Summer outdoor temperature is not high, relative humidity is moderate but indoor/outdoor temperature-difference is larger or summer outdoor temperature is not high but phase Or summer outdoor temperature larger to wet difference is run when higher:Backheat after the process operation of heat pump first freezes to fresh air, i.e., first to new Dry but colder fresh air is heated to above 2 DEG C or so of dew-point temperature with a small amount of heat after wind dehumidifying, prevents indoor fresh air Air port surface temperature it is relatively low moisture condensation and cause local humidity.It, can be relatively more nice and cool to people since the temperature and humidity of fresh air are relatively low Feel, the air in space near fresh air export direction, moreover it is possible to which the requirement for meeting Smaller load partial cooling air-conditioning also reduces simultaneously The cooling load of entire room conditioning.
It is process six, standby
When it is indoor nobody with it is relatively dry when, equipment is in standby, and fresh-air fan is also out of service;Phase in waiting room When higher to humidity, equipment is automatically switched to other fresh air dehumidification process operations again.
The control logic of six processes of the above-mentioned different break-make combinations of load, equipment become according to indoor and outdoor temperature and relative humidity Change, is carried out by 7 energy-optimised application multifunctional heat pump fresh air damping machine control logic block diagram of attached drawing, it is oxygen-containing to reach room air Measure requirement of the sufficient and relative humidity in comfortable range and equipment high efficiency energy-saving run.
This equipment advantageous effect be to provide a kind of fresh-air ventilation, dust removal by filtration, comfortable damping, energy-efficient, installation is simple, It is easy to use, manufacturing cost is low, installed power is small, operating cost is low, air draft cold and heat recovery, all-weather intelligent operation, Smaller load Local air conditioner, the indoor annual device that can realize permanent oxygen constant humidity for 365 days.
The Smaller load part air conditioner that this equipment provides ensures the comfortable air themperature of a small range around air outlet. In general, when meeting the requirement of a whole set of or whole room space fresh air volume, due to being sent into indoor fresh air with cool in summer and warm in winter Attribute, fresh air export direction nearby space air, moreover it is possible to meet the requirement of Smaller load part air conditioner.Ensureing fresh air While, it also can be used as the long-term single fixed dwell regional air conditioner such as study and cubicle and use.
This equipment operation of heat pump carries out heating just for the fresh air got on a small quantity and is handled with refrigerated dehumidification, so heat pump Refrigerating capacity and heating capacity needed for operation is also small, i.e. the electric energy of equipment operation consumption is also small.In comparison, generally there was only air-conditioning system / 10th or so of cold heating consumption electric energy.
Combine and compare with dehumidifier with traditional new wind turbine on this device structure, or with conventional central air-conditioning and fresh air system phase Than simple in structure relatively low with cost.
This equipment is for the weather of different temperatures and humidity, corresponding fresh air preheating device operation of heat pump fresh air heating, heat pump fortune The heating of row fresh air, the heating of operation of heat pump fresh air refrigerating, ventilation are controlled automatically with operation of heat pump fresh air refrigerating backheat, standby six processes System, has reached intelligent operation and requirement easy to use, and reach the low requirement of equipment operating cost.
This equipment is compared with traditional fresh air dehumidifier, or combines and compare with dehumidifier with traditional new wind turbine, or in tradition Centre air-conditioning and fresh air system are compared, the operation as required that there is heat pump annual 365 days, the cold and hot energy four seasons optimization application of heat pump with it is every When often carve intelligence adjust indoor relative humidity the characteristics of, it is ensured that indoor air relative humidity is all comfortable on range in people daily Within.Meanwhile the fresh air that this equipment summer filters to indoor feeding, dehumidifies with low temperature after backheat, winter is to indoor feeding Filtering and the fresh air after heating, filtering season heat to fresh air filtering or after freezing on demand.Winter fresh air is using heating Heating treatment, indoor temperature can be improved 1~2 DEG C;Summer fresh air is handled using refrigerated dehumidification cooling, and indoor temperature can reduce by 1~2 ℃;And the relative humidity of room air is all reduced, the sendible temperature of winter people is felt to improve 2~3 DEG C, the body of summer people Sense temperature sensation reduces 2~3 DEG C, therefore can reduce the usage time of cold/hot air-conditioning, and air-conditioning using when reduce air-conditioning Load, or increase the effect of air-conditioning.
In addition, the cold air or hot-air of indoor discharge, its sensible heat obtains height with latent heat when surface cooler cold and hot by air draft Effect recycling, higher than the organic efficiency several times of traditional fresh air dehumidifier indoor and outdoor air two-way flow total-heat exchanger, and favorably The operating condition for improving heat pump in two season of summer in winter improves the Energy Efficiency Ratio of heat pump, reduces the consumption of compressor electric energy.
In this equipment complex current room air adjusting field fresh air dehumidification the problem of being primarily present and technological difficulties, It combines and compares with dehumidifier with traditional new wind turbine, or compared with conventional central air-conditioning and fresh air system, the work(with a tractor serves several purposes Can, it is with a wide range of applications in places such as family, hotel, meeting room, hotel and basements, it is good more to meet people's needs Good air quality brings the requirement of benefit to life with health.
