Description

A kind of wind pipe type CO2 air conditioner and heat pump units
Technical field
The invention belongs to technical field of air-conditioning heat pumps, more particularly to a kind of wind pipe type CO2Air conditioner and heat pump unit.
Background technology
Airduct unit is will to be connected between an outdoor unit and an indoor set with copper pipe, from cold wind caused by indoor set (warm wind) draws ajutage and leads to each room, then sends indoor set back to by backwind tube, through cooling down (heating) and mixing portion is new Sent out again after wind, be a kind of central air-conditioning of brand-new air system.Energy-saving effect is obvious, and air pipe air conditioner source pump belongs to direct-cooled Formula system, evaporating temperature is higher, and in the case where other conditions are certain, the efficiency and energy of unit can be improved by improving evaporating temperature Effect ratio.Wind pipe type unit air-conditioner unit capacity is larger, disclosure satisfy that refrigeration (heat) requirement in the more rooms in a family, it is very square to supplement fresh air Just, sending the arrangement in air port back to can need flexibly to carry out according to finishing, and indoor cold-hot wind is evenly distributed, air ambient comfort level It is higher.The use of the supply air system of wind pipe type unit air-conditioner unit is extremely widespread in the U.S., be suitable for U.S. room it is tall and big it is spacious, Extensive individual demand.In recent years, such a air-conditioner set also had not in some economically developed big cities such as Beijing, Shanghai etc. Few uses example, particularly some high-grade villa buildings.But its shortcoming is mainly that noise is larger, it is sometimes desirable to considers noise reduction Measure.System installation is more complicated, and certain interior space should be taken by sending the arrangement of airduct back to, and interior is hung item and matched therewith again Close, indoor set is also required to take certain careat or space, to place, to be less suitable for the national conditions of China.Send in each room Return air also brings the problem of epidemic disaster is not easy to adjust in each room room, certainly while indoor environment comfort level is improved Motorized adjustment air-valve can be used, this another aspect adds system cost, also increases the difficulty of system fading margin and control in addition Degree and complexity, it is spend and inconvenient after all for family's use more.
Wind pipe type unit air-conditioner unit mainly has two kinds of typical mounting means according to its difference for heating mode:One kind side Formula is to use air-cooled heat pump type Split cabinet type air-conditioner set, and indoor cabinet is aided in inject formula heater, it is possible to provide 5kw- 20kw electric heating increment, the conversion of summer in winter operating mode is realized by the commutation of four-way valve;Another typical mounting means is room Interior machine is combined into high efficiency burnt gas heating furnace, system humidifier and electronic filter, and outdoor unit is then air-cooled single cold type, with Summer and winter Cooling or heat supply are realized in the conversion of section.Electronic filter is arranged on return air house steward, and humidifier is installed on header pipe, is used To add water vapour into wind pushing air in heat supply mode, the humidity of room air is improved.
Traditional air-duct-type air-conditioner source pump, mostly using traditional working medium such as R22, R134a, the feature of environmental protection is poor, faces The trend being gradually eliminated.System is when running dehumidification mode, it is necessary to assisted heating device be opened, to the air progress after dehumidifying Heating, to reach comfortable temperature.On the one hand such assisted heating device makes system become complicated, add equipment cost, On the other hand, energy consumption during system operation is improved, makes the reduction of system heating efficiency.In addition, traditional air-duct-type air-conditioner heat pump Unit operating pressure is relatively low, and using the energy-saving effect unobvious of injector, substantial amounts of expansion work is wasted, and systematic function is relatively low.
The content of the invention
It is an object of the invention to provide a kind of wind pipe type CO2Air conditioner and heat pump unit, utilize CO2Heat pump pattern is heated, By changing gas four-way reversing valve and liquid four-way reversing valve, refrigeration mode can be directly translated into.It is not required under dehumidification mode Electrical heating is wanted, air-valve is opened, and second gas cooler accesses indoor wind path, and the air after dehumidifying is heated, reached Suitable temperature.System utilizes an eductor as booster pump, and systematic function is higher.
