Description
Technical field
The present invention relates to technical field of heat pumps, is particularly suitable for timber machining enterprise, the heat pump assembly in wood conditioning room.
Background technology
Dried timber is during transport or storage, so that the moisture content of timber is changed, either due to the influence of the factor such as water translocation characteristic in Wood Properties Within, dry kiln structure and timber, so that the moisture content of timber still has situation pockety in same dry kiln, it is this it is uneven be both embodied between different plates, be also embodied between internal layer and the top layer of same sheet material.The defects of to be deformed, ftractureing during reducing timber machining, health processing must be carried out before dried timber machining.
In the prior art, health processing of many enterprises for dry wood is symbolic or only placed by rule of thumb several days, even if there is the enterprise of health preserving room, health preserving room temperature also only ensures health preserving room temperature by burning waste wood or coal.The method of such a offer thermal source is simple, but health preserving room temperature, humidity are difficult to ensure that, and the feature of environmental protection is poor.
The content of the invention
For above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of heat pump assembly suitable for wood conditioning room.It can meet the temperature requirement of health preserving room, and and can realizes its humid control, effectively raise health efficiency and health effect, and automaticity is high, pollution-free environmental benefit is good.
In order to reach foregoing invention purpose, technical scheme is realized as follows：
A kind of heat pump assembly suitable for wood conditioning room, it is structurally characterized in that, it is in turn connected to form annular heat pump by evaporator, compressor, condenser and expansion valve.Valve one is equipped with the outdoor blast pipe being connected with evaporator, valve two is equipped with the exhaust duct being connected with evaporator, valve three is equipped with the indoor blast pipe being connected with evaporator.Valve five is equipped with the indoor blast pipe being connected with condenser, valve four is equipped with the air inlet pipeline that evaporator is connected with condenser.
The present invention provides thermal source as a result of said structure, heat pump assembly using electric drive, substitutes coal-fired（Oil）Boiler and wood chips burning stove, local contamination-free air draft, protect outdoor air environment.Apparatus of the present invention are preventing the craze and transfiguration of timber, the uniformity for realizing timber end moisture content etc. preferably, and automaticity is high, environmental benefit is good.
The invention will be further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
Referring to Fig. 1, the present invention is applied to the heat pump assembly in wood conditioning room, and it is in turn connected to form annular heat pump by evaporator 1, compressor 2, condenser 3 and expansion valve 4.Valve 1 is equipped with the outdoor blast pipe being connected with evaporator 1, valve 26 is equipped with the exhaust duct being connected with evaporator 1, valve 37 is equipped with the indoor blast pipe being connected with evaporator 1.Valve 59 is equipped with the indoor blast pipe being connected with condenser 3, valve 48 is equipped with the air inlet pipeline that evaporator 1 is connected with condenser 3.
Apparatus of the present invention have three kinds of operational modes when working, each pattern realizes automatic conversion all in accordance with the humiture requirement of health preserving room：
1）Operational mode is heated, i.e. heat pump assembly heating operation realizes health preserving room heat demand.When health preserving room temperature is less than temperature needed for wood conditioning technique, source pump starts heating mode valves 1, valve 26 and valve 59 are opened, valve 37 and valve 48 are closed, outdoor air enters evaporator 1, in evaporator 1 heat exchange is carried out with refrigerant, row arrives outdoor after cooling, compressor 2 absorbs the refrigerant vapour for carrying out flash-pot 1, row arrives condenser 3 after increasing temperature and pressure, in condenser 3 heat exchange is carried out with the Cryogenic air in health preserving room, transfer heat to after Cryogenic air and enter evaporator 1 through the throttling cooling of expansion valve 4, complete system circulation, absorb the air of heat, temperature rise is sent back in health preserving room, precondition is provided for wood conditioning.
2）Dehumidification operating mode, after humidity is more than setting value, apparatus of the present invention open dehumidification mode, reduce the humidity in wood conditioning room to meet the technological requirement of wood conditioning.When health preserving room humidity is higher than process requirements, unit starting dehumidification mode, valve 1, valve 26 and valve 59 are closed, valve 37 and valve 48 are opened, hot and humid air in health preserving room enters evaporator 1, carries out heat exchange in the evaporator 1 with refrigerant, and the cold dry air after cool-down dehumidification enters condenser 3, it is heated up in condenser 3 and becomes heated dry air and send back to health preserving room, completes system circulation
3）Ventilation operational mode, when temperature, humidity are all higher than setting value, ventilation valve is automatically turned on, realizes health preserving room and extraneous air exchange.When temperature humidity is above technological requirement in health preserving room, it is uneconomical now to drive dehumidifier, opens vented exhaust valve and is aerated ventilation.Valve 1, valve 26, valve 37, valve 48 and valve 59 are opened, and compressor 2, evaporator 1, condenser 3 and expansion valve 4 are not run, only fan operation.
Above-mentioned three kinds of operational modes, which automatically switch, to be run, and meets wood conditioning requirement, and realize energy-saving run.
