Description
Technical field
The present invention relates to fresh air equipment technical field, more particularly to a kind of fresh air heat pump all-in-one.
Background technology
With the continuous improvement of economic condition, air-conditioning is increasingly popularized, and enters average family, solves summer day
The problem of gas sweltering heat winter cold, indoor environment can be adjusted the temperature to human comfort, but economic rapid development, band
Problem of environmental pollution is seriously carried out, such as dust, toxic and harmful gas.To family and office space, effective solution is
New blower fan is installed, it is a kind of effective air cleaning facility, room air can be made to produce circulation, on the one hand foul indoor
Air discharge it is outdoor, on the other hand outdoor ozone by sterilizing, after the measure such as sterilization, filtering, then be input to room
It is interior, allow in room be all the time fresh clean air, new blower fan uses fresh air convection techniques, by independently blowing and drawing
Wind, room air is set to realize convection current, so as to the carry out room air displacement at utmost changed, multifunctional purifying system built in new blower fan
The air cleaning health that blanket insurance card is got in, still, the thing followed are the substantial amounts of electric energy of consumption, according to statistics, air-conditioning and new
Blower fan power consumption is most important equipment in building, accounts for more than 60%.If product efficiency can be improved, energy will be substantially reduced
Consumption, total-heat exchanger arise at the historic moment.It is that outdoor live gas is passed through filtering, purification by one kind, and room is sent into after heat exchange process
It is interior, at the same indoor contaminated pernicious gas carried out again discharging after heat exchange process it is outdoor, and indoor temperature substantially not by
A kind of energy-efficient, the high-tech product of environment-friendly type of new wind effect, according to prior art, at present to homes and offices, greatly
More installation air-conditioner sets, then equipped with air purifier or new blower fan, exist major problem is that：First, air-conditioner set efficiency is low,
When especially summer outdoor environment is high, heat exchanger heat transfer effect is undesirable, and condensation temperature is high, causes efficiency low, similarly, winter
When, outdoor temperature is low, and evaporating temperature is low, causes that unit operation efficiency is low, and power consumption is big；2nd, air-conditioner set noise is big, to solve
The demand of high-temperature refrigeration and low-temperature heating causes high noise, reduces air-conditioner set, it is necessary to the air quantity of outdoor unit and indoor set is big
Comfortableness；3rd, take up space, new blower fan or the installation of fresh air total-heat exchanger indoors, realize inletting fresh air, but installation cost
Height, and the interior space is occupied, give people to cause sense of depression；4th, cost is high, should buy, install air-conditioner set, while again
Buy, new blower fan is installed, price is high.
The content of the invention
The technical problems to be solved by the invention are：A kind of the defects of overcoming above prior art, there is provided air-conditioner set energy
Effect is high, air-conditioner set noise is small, does not take up space and fresh air heat pump all-in-one that cost is low.
The technical solution used in the present invention is：A kind of fresh air heat pump all-in-one, including fresh air heat pump machine body, it is described
Fresh air heat pump machine body includes heat pump and VMC, and described heat pump includes compressor, four-way valve, the first heat exchange
Device, the second heat exchanger and electric expansion valve, described VMC include fresh air air-introduced machine and exhaust blower, and it also includes heat exchange filter
Core and conversion valve, described fresh air air-introduced machine are provided with the first pipeline that outdoor fresh air is introduced, the first described pipeline
The second pipe in parallel with the first pipeline is provided with, described conversion valve is located in the first pipeline, set on described exhaust blower
Have and room air is gone out second pipe and the 3rd pipeline are divided into two respectively to the 3rd pipeline of outdoor, described heat exchange filter core
Section, one end of described First Heat Exchanger are connected by four-way with the blast pipe of compressor, and described First Heat Exchanger is another
End is connected by electric expansion valve and the second heat exchanger；One end of the second described heat exchanger passes through four-way valve and compressor
Air intake duct is connected, and described compressor, the first heat exchange, electric expansion valve and the second heat exchanger have been sequentially connected in series by pipeline
Come, the exhaust port (the D mouths of pipe) of described four-way valve is connected with the exhaust outlet of compressor, the C mouths of pipe, the E of described four-way valve
The mouth of pipe, the S mouths of pipe are connected with First Heat Exchanger, the second heat exchanger, compressor return air mouth respectively.
After above structure, the present invention has advantages below compared with prior art：Heat recovery fresh air module is arranged on
In outdoor unit, save it is indoor indoor apparatus of air conditioner and new blower fan are installed again, there is obviously advantage, one, efficiency it is high, power consumption
Reduce, on the one hand in total-heat exchanger filter element, outdoor fresh air carries out heat exchange with indoor machine wind-discharging, and outdoor fresh air absorbs row
The heat of wind, energy-conservation energy consumption；Still further aspect, the indoor machine wind-discharging after being exchanged heat in filter core are changed with outdoor unit heat exchanger
Heat, during cooling in summer, because the temperature of outgoing air of indoor set is low, good effect of heat exchange, condensation temperature can be reduced, improve efficiency.Winter
Its heating, indoor machine wind-discharging temperature can improve evaporating temperature, improve efficiency higher than outdoor environment temperature；2nd, winter system
Heat, air-conditioner set outdoor heat exchanger frost-free, winter heating, outdoor heat exchanger carries out heat exchange with indoor machine wind-discharging, indoor
Machine temperature of outgoing air is higher than outdoor environment temperature, can improve evaporating temperature, and heat exchanger frost-free or few frosting, improves
Winter heating effect, ensure the comfortableness that can be used；3rd, noise is low, and due to heat exchanger good effect of heat exchange, fan delivery can be with
Reduce, following noise is low.In addition, it is not necessary that installation indoor set and new blower fan, avoid room noise；4th, installation is simple just
Victory, mounting cost substantially reduce, and save installation indoor set and new blower fan or total-heat exchanger, can avoid because installation is indoor
The sense of depression that the story height that machine and new blower fan are brought reduces, does not take up space.
