Description

The new blower fan group of severe cold area air-conditioning waste heat recovery air source heat pump
Technical field
The utility model belongs to heating and refrigeration association system technical field, is specifically related to a kind of new blower fan group of air source heat pump of carrying out waste heat recovery at severe cold area that has.
Background technology
At present, be used for room conditioning, do the alternating temperature processing and do not make alternating temperature processing dual mode importing indoor new wind.New wind is not handled, new wind is directly introduced the air-conditioned room mode, low at cold district, fluctuation is big because of outdoor new wind-warm syndrome degree, cause the air-conditioned room indoor temperature change generated in case bigger, can't satisfy the requirement of air quality, range of application is narrower, seldom uses at cold district.To send into conditioned space after the air-treatment, two kinds of ways were arranged in the past.A kind of is to adopt brand-new wind air-treatment unit, and another kind is to adopt heat reclamation device to carry out air-treatment.Brand-new wind air-treatment unit structural principle as shown in Figure 1.Comprise fresh wind tube road 1, exhaust duct 2, blower fan 5, heat exchanger 4, electrical heating heat exchanger 3, electric thermal insulating air-valve 6 are again arranged in the fresh wind tube road 1.Blower fan 7, electric thermal insulating air-valve 8 are arranged in the exhaust duct 2.The new wind processing capacity of the new wind treating apparatus of this kind extremely a little less than.Particularly in severe cold area winter, because of winter outside air temperature low, in traditional new blower fan group or the assembled air-conditioner unit water heat(ing) coil, the hot water temperature is low, flow velocity is little, often freezes the damage accident, causes and can not normally move, indoor air quality can not guarantee.Heat reclamation device mainly contains board-like and rotary-type heat reclamation device, and wherein plate-type heat recovery device only can reclaim the sensible heat amount, can't fully reclaim the energy, and rotary-type heat reclamation device causes the phenomenon of new wind and the mutual cross pollution of air draft easily.
Summary of the invention
The purpose of this utility model provides the new blower fan group of a kind of severe cold area air-conditioning waste heat recovery air source heat pump, be used for the cold district room air and regulate and to handle, overcome to freeze in winter that existing new wind treating apparatus exists and decrease or new wind and air draft cross pollution phenomenon importing indoor new wind.
The utility model is by compressor, four-way change-over valve, the electric three passes control valve, motor-driven valve, non-return valve, throttling arrangement, liquid separator, the fresh wind tube road and be installed in blower fan in the fresh wind tube road, by season alternately as two or two groups of heat exchangers of evaporimeter or condenser, exhaust duct and be installed in blower fan in the exhaust duct, alternately form as evaporimeter or condenser one or one group of heat exchanger by season.
The annexation of each member is: the compressor high-pressure outlet connects an interface of four-way change-over valve, and low pressure inlet connects the liquid separator outlet.Three interfaces in addition of four-way change-over valve connect head end, electric T-shaped valve and the liquid separator of pressing first heat exchanger of air intake direction in the fresh wind tube road with pipeline respectively.Electric T-shaped valve two interfaces in addition connects end and the motor-driven valve of pressing air draft direction heat exchanger in the exhaust duct with pipeline respectively.Another interface of motor-driven valve connects the end of second heat exchanger in the fresh wind tube road with pipeline.Heat exchanger head end in the end of first heat exchanger in the fresh wind tube road and the exhaust duct is connected with the pipeline that has throttling arrangement, and the pipeline that the head end usefulness of second heat exchanger in the fresh wind tube road has a non-return valve is connected on the heat exchanger head end and the pipeline between the throttling arrangement in the exhaust duct.More than be basic scheme of the present utility model.
New blower fan group in the such scheme can be a monoblock type, or cuts apart the split type of combination according to construction style.New blower fan group can be that heat pump (winter, spring and autumn) also can be single cold combined air conditioner machine (summer).The blower fan that is utilized can be centrifugal blower or axial flow blower or air conveyance devices.Employed throttling arrangement is one or one group of expansion valve, or capillary or other have the device of throttling function.
The flow that needs for air draft sometimes is greater than the influence of new wind flow to room pressure, connects logical outdoor outdoor wind mixing wind tube road at the air intake of exhaust duct.
Indoor temperature when keeping unit outage is equipped with motorized adjustment insulation air-valve on the end of the head end in fresh wind tube road, exhaust duct and mixing wind tube road.
Good effect of the present utility model is: in the winter time, adopt the condenser of source pump to heat introducing indoor new wind, when having avoided winter operation, outdoor cold air is to the damage of freezing of water heat(ing) coil in the new blower fan group of tradition; To build the heat transferring medium of air draft (or premixer's outer air), reclaim building air draft heat, realize the recuperation of heat effect as the new blower fan group of heat pump evaporimeter; Simultaneously can improve the performance of source pump at the severe cold area winter operation.Realize to guarantee new wind ventilation state, satisfied the needs of air-conditioning system work and health, realized the effect of recuperation of heat simultaneously.Air-supply passage and air exhaust passage are independent respectively, can not cause the cross pollution of new wind and air draft.
