The operation principle of the utility model flash baking dehumidifying source pump is as follows: cold-producing medium working medium becomes the low-temp low-pressure gas compression gas of HTHP under the piston action of compressor; High temperature and high pressure gas is cooled into liquid after entering condenser, thereby emits large calorimetric, and cold air absorbs its heat and temperature constantly rises and become high-temperature hot air; Cold-producing medium working medium is by after condenser, enter again fluid reservoir, filter, choke valve, then evaporate in evaporimeter, heat in absorbing environmental enters compressor at last, so iterative cycles, cold-producing medium working medium absorbs the heat of air in evaporimeter, under the mechanism of compressor, emit heat from condenser, change the heat of hot blast into; Whole source pump is used contrary Carnot cycle principle, doing work by heat pump makes heating agent (refrigerant) produce physical phase transition (liquid state-gaseous state-liquid state), utilize the characteristic of uninterruptedly absorbing heat in the reciprocation cycle phase transition process with heat release, draw the airborne heat of low-temperature heat source by heat sink (evaporimeter), by dedicated heat exchanger (condenser) constantly heat release in the cold air, make cold air be warmed up to gradually high-temperature hot air; The electric heating energy conversion efficiency that heats in process reaches as high as more than 450%, heat pump only need to consume a fraction of electric energy and satisfy the equipment actings such as compressor and blower fan, just can with being in the hot-air of the airborne transfer of heat of low temperature environment under the hot environment, remove to heat the hot-air of producing room high temperature.
When source pump needs hydrofuge, just open the second blower fan and reach the function of hydrofuge, when need to heating for the first time, unit starts the second blower fan, at this moment section of jurisdiction heat exchanger comes the airborne heat of suction chamber external environment as evaporimeter, and the section of jurisdiction heat exchanger as evaporimeter also has dehumidification function simultaneously.When the indoor temperature of bakery need to be lowered the temperature, section of jurisdiction heat exchanger was at this moment taken away heat as condenser through the outdoor environment air, and condenser at this moment has been to be cold function, and at this moment the evaporating temperature of evaporimeter can be lower, and the effect on moisture extraction of this moment is good especially.Unit does not need to begin the temperature that hydrofuge air door and new air door reduce bakery like this, reaches the better quality, much cleaner of baked good.
Be provided with sensible heat recoverer in source pump, it is mainly the air that the temperature heat of the hot and humid air of indoor return air passes to the low humidity low temperature after indoor dehumidification, make through the hot and humid air after recuperation of heat further cooling, the cold air of the low temperature and low humidity that its cooling heat is come by evaporimeter is taken away, play the optimum efficiency of cold air preheating, thereby make hot and humid room air become the room air of high humidity low temperature after recuperation of heat, the room air of high humidity low temperature can be removed more moisture through evaporimeter, reaches fast dehumidifying and more energy-conservation effect.
Use the technical scheme of the utility model oven dry hydrofuge source pump, have following effect:
(1) utilize air-source only to need directly will be in the hot-air of the airborne transfer of heat of low temperature environment under the hot environment by a small amount of electric weight, environmental protection, safe, pollution-free, energy savings, cost saving.
(2) the utility model dehumidification equipment with sensible heat recoverer, improves heat exchange effect.
(3) fresh wind port is provided with the first electrically operated valve outward, and moisture exhausting port is provided with the second electrically operated valve outward, can better control the temperature of drying equipment inside.
(4) choke valve is heating power expansion valve or electric expansion valve, easily controls.
(5) be provided with successively reservoir and filter between heat exchanger and choke valve, be provided with vapour liquid separator between heat sink and compressor, make the thermostatic control of the utility model dehumidification equipment more stable.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
