Summary of the invention
The objective of the invention is the deficiency for the prior art existence, a kind of condensation heat recovery type air-conditioning unit is provided, utilize the condensation heat of the generation of unit to substitute conventional electricity (or steam, hot water) heater block, energy-conserving and environment-protective, reduce the unit power consumption, and the step-less adjustment of realization unit blasting air temperature, satisfy the required precision of room humiture.
For achieving the above object, the technical solution used in the present invention is that a kind of stepless-adjustment warm type condensation heat reclaims the air-conditioning unit, comprise refrigeration compressor, device for drying and filtering, liquid reservoir, condenser, evaporimeter, recuperation of heat reheater and centrifugal blower, the refrigeration compressor exit is provided with the threeway ratio adjusting valve, 2 outlets of threeway ratio adjusting valve connect respectively recuperation of heat reheater entrance and condenser inlet, and the outlet of recuperation of heat reheater and condensator outlet remerge the entrance that is connected to liquid reservoir by check valve respectively; The input port of refrigeration compressor is communicated with the delivery outlet of evaporimeter, and the reservoir outlet is communicated with the input port of evaporimeter by stop valve, device for drying and filtering, magnetic valve, heating power expansion valve successively; Press air-flow direction, be provided with successively recuperation of heat reheater and centrifugal blower behind the evaporimeter.
Described threeway ratio adjusting valve is the continuous quantity adjustment type.
Described recuperation of heat reheater is finned heat exchanger.
Described condenser is air-cooled or water-cooled.
Also be provided with successively heater and humidifier between described recuperation of heat reheater and the centrifugal blower.
Air then through behind the condensation heat recovery reheater temperature setting, adjusts wind-warm syndrome humidity first by the evaporimeter cool-down dehumidification, reaches the control accuracy of room temperature.Regulate the heat that adds of recuperation of heat reheater by the threeway ratio adjusting valve, realize the step-less adjustment of leaving air temp.
Beneficial effect: the present invention reclaims reheater by increase condensation heat in the evaporimeter air side, the condensation heat of utilizing the refrigeration system operation to produce replaces electrical heating or other thermal source, air is first by the evaporimeter cool-down dehumidification, then reclaim the reheater regulating outlet air temperature through condensation heat, can utilize condensation heat to reduce unit air-out relative humidity.Owing to having utilized the condensation heat of refrigeration system, during dehumidifying with utilize electric heater compare energy-conservation obviously, the power consumption of air-conditioning unit reduces greatly; Owing to having used the threeway ratio adjusting valve, adjustable restraining cold compressor is vented to the ratio of condenser and condensation heat recovery reheater, thereby step-less adjustment enters the refrigerant flow that condensation heat reclaims reheater, reclaiming reheater and refrigeration system in condensation heat is equipped with when suitable, but the again heat that the step-less adjustment unit needs, has the leaving air temp precision high, the characteristics of leaving air temp step-less adjustment.Unit can suitably increase some other control measure according to different instructions for uses.This unit refrigerating operaton operating mode is stable, and is safe and reliable, and set structure is compact, reasonable in design.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, the present embodiment is implemented under take technical solution of the present invention as prerequisite, should understand these embodiment and only be used for explanation the present invention and be not used in and limit the scope of the invention.
As shown in Figure 1, a kind of stepless-adjustment warm type condensation heat recovery type air-conditioning unit, comprise refrigeration compressor 1, the output of refrigeration compressor 1 connects the input of refrigeration compressor 1 successively by threeway ratio adjusting valve 8, condenser 7, recuperation of heat reheater 10, check valve 6, liquid reservoir 5, stop valve 4, device for drying and filtering 3, magnetic valve 2, expansion valve 14, evaporimeter 9.Be provided with successively evaporimeter 9, recuperation of heat reheater 10, heater 12, humidifier 13 and centrifugal blower 11 on the circulation of air path.Condenser 7 is connected with the recuperation of heat reheater and is that parallel way connects, condenser 7 and 10 outlets of recuperation of heat reheater all are furnished with check valve 6, the air inlet of recuperation of heat reheater is connected to wherein 1 outlet of threeway ratio adjusting valve 8, the condenser air inlet is connected to wherein in addition 1 outlet of threeway ratio adjusting valve 8, the refrigeration compressor exhaust outlet is connected to the entrance of threeway ratio adjusting valve 8, and the liquid outlet of the liquid outlet of recuperation of heat reheater 10 and air-cooled condenser 7 is connected to the inlet of liquid reservoir 5 by check valve 6.
Threeway ratio adjusting valve 8 is arranged on the delivery outlet of refrigeration compressor among the figure, also can be arranged on the input port of liquid reservoir 5.Condenser 7 is air-cooled among the figure, also can become water-cooled, and this variation also is the scope of this patent.
Refrigerated dehumidification principle of the present invention is: the high-temperature high-pressure refrigerant gas that refrigeration compressor 1 is discharged enters condenser 7 and recuperation of heat reheater 10, be condensed into middle temperature highly pressurised liquid, the vapour-liquid two-phase mixture that becomes low-temp low-pressure behind heating power expansion valve 14 reducing pressure by regulating flows enters evaporimeter 9, vapour-liquid two-phase mixture evaporimeter 9 interior absorptions flow through evaporimeter 9 the air heat and evaporate, the air of the evaporimeter 9 of flowing through is lowered the temperature, because evaporimeter 9 fin surface temperature are lower than the dew-point temperature of air, air stream is when evaporimeter 9 surface, there is moisture content to separate out on evaporimeter 9 surfaces, air absolute humidity through evaporimeter 9 reduces, and reaches the dehumidifying purpose.Cold-producing medium is more cooled compressor 1 suction after evaporimeter 9 heat absorption vaporizations, discharges after the compression, so circulation again.
When space moisture load and refrigeration duty change, by adjusting the open degree of threeway ratio adjusting valve 8, regulate the refrigerant flow of recuperation of heat reheater 10, when guaranteeing the unit moisture removal, regulate the unit leaving air temp, adapted to humidity load and refrigeration duty and changed.Because threeway ratio adjusting valve 8 is regulated for continuous quantity, the leaving air temp of unit can be accomplished step-less adjustment.Air after the processing is sent into air-conditioned room through blower fan 12.
Unit Temperature Setting of the present invention is at 18 ℃～30 ℃, and by recuperation of heat reheater 10 and threeway ratio adjusting valve 8 are set, the condensation heat that produces in the time of can taking full advantage of refrigerating operaton replaces electrical heating or other thermal source.Owing to having utilized the condensation heat of refrigeration system, during dehumidifying with utilize electric heater to compare energy-conservationly obviously to have reduced simultaneously the heat exhaust of condenser, unit operation efficiency is higher, the operate power of air-conditioning unit reduces simultaneously, and the Temperature and Humidity Control precision is higher and can realize the continuous quantity adjusting.
But unit threeway ratio adjusting valve open degree step-less adjustment of the present invention, the temperature of unit maintain in the temperature range of requirement and have higher precision, and the leaving air temp of unit increases along with threeway ratio adjusting valve open degree and raises; And the general power of unit reduces along with the increase of threeway ratio adjusting valve open degree, and unit operation efficiency is high.
