Abstract

The utility model relates to a multifunctional heat pump drier, which is characterized in that a compressor (1), a condenser (4), an expansion valve (3), and an evaporator (2) are orderly connected; the rear part of the evaporator is provided with a main fan (5); the interior of a drying chamber (8) is provided with a stack (7), the upper part of the stack is provided with a circulation fan (6), the air inlet end of the drying chamber is communicated with the main fan, and the air outlet end of the drying chamber is communicated with rotary air valves (I and III); both sides of the evaporator are provided with translational air valves (a and b), and a rotary air valve (II) is arranged on the side upper part of the translational air valve (b). The multifunctional heat pump drier uses a set of refrigeration system, and realizes a dehumidifying function, a heat supplying function and a moisture exhausting function by converting the position of the air valve. Compared with a heat pump with double evaporators, the utility model has the advantages of low cost, and low energy consumption. Meanwhile, because the drying chamber with the moisture exhaust function is added, an auxiliary exhaust outlet and a ventilation fan can not be provided. Thus, not only the heat loss is reduced, but also the cost of the drying chamber is reduced.

Description

The multifunctional heat pump drying machine
Technical field
The utility model relates to a kind of multifunctional heat pump drying machine of wood processing field.
Technical background
At present two thermal source pump drying machines have dehumidifying and two working cycles of heat pump, two evaporimeters, a shared compressor and a condenser.The dehumidifying circulation time, refrigeration working medium absorbs heat from the humid air that hothouse is discharged in the dehumidifying evaporimeter; During heat pump cycle, refrigeration working medium absorbs heat from atmospheric environment in the evaporator with heat pump.Find out that thus this technical performance is single, the cost height.
Summary of the invention
In order further to improve the performance of heat pump drier, reduce product cost and energy consumption, invent and a kind ofly the shared refrigeration system of heat pump of wet dehydration, heat pump heat supply and three kinds of functions of hothouse hydrofuge is fallen in humid air and have the multifunctional heat pump drying machine of realizing difference in functionality by the position of changing air-valve in the heat pump.
The purpose of this utility model is a kind of multifunctional heat pump drying machine of realizing in the following manner, it is characterized in that: compressor (1), condenser (4), expansion valve (3), evaporimeter (2) connect successively, and main air blower (5) is placed at described condenser rear portion; Inner material heap (7) its top of placing of hothouse (8) is provided with circulating fan (6), and described hothouse air intake communicates with main air blower, and its air outlet communicates with rotary air valve (I, III); Described evaporimeter both sides are provided with translation air-valve (a, b), described translation air-valve (b) arranged outside rotary air valve (II).
The air outlet of described hothouse (8) communicates with rotary air valve (I, II), simultaneously described rotary air valve (III) and translation air-valve (a, b) closure.
The air outlet of described hothouse (8) communicates with rotary air valve (III) and translation air-valve (a, b), simultaneously described rotary air valve (I, II) closure.
The air outlet of described hothouse (8) communicates with rotary air valve (I, II) and translation air-valve (b), simultaneously described rotary air valve (III) and translation air-valve (a) closure.
The main feature of multifunctional heat pump drying machine: function is many, and cost is low, less energy consumption.Adopt a cover refrigeration system, utilize conversion air-valve position, can realize dehumidifying, heat supply and three kinds of functions of hydrofuge.Compare with the heat pump of double evaporators, its cost has reduced about 10%.Can not establish auxiliary exhaust mouth and ventilation fan owing to increased hydrofuge function hothouse simultaneously, so promptly reduce heat loss, reduce the cost of hothouse again.

Specific embodiment
Compressor (1), condenser (4), expansion valve (3), evaporimeter (2) connect successively, and main air blower (5) is placed at described evaporimeter rear portion; Inner material heap (7) its top of placing of hothouse (8) is provided with circulating fan (6), and described hothouse air intake communicates with main air blower, and its air outlet communicates with rotary air valve (I, III); Described evaporimeter both sides are provided with translation air-valve (a, b), described translation air-valve (b) arranged outside rotary air valve (II).
Remove wet cooling condition: valve (I, II) is opened, valve (III) and valve (a, b) are closed, and the interior humid air of hothouse (8) (9) dehumidifies through valve (I), evaporimeter (2), and the dry air after the dehumidifying is through valve (II), locate to be heated at condenser (4), send into hothouse by main air blower (5) then.
The heat pump heat supply operating mode: valve (I, II) cuts out, valve (III) and valve (a, b) are opened, heat pump blower fan this moment (failing among the figure to draw) orders about surrounding air and crosses the threshold from valve (a), carries out heat exchange through evaporimeter (2) with refrigeration working medium in the evaporimeter, enters in the atmosphere from valve (b) door then; On the other hand, the humid air in the hothouse is closed because of valve (I, II), can only pass condenser (4) through valve (III) and be heated, and be sent in the hothouse this heating cycle that promptly do not dehumidify by main air blower (5).The hydrofuge operating mode: valve (I, II) and valve (b) are opened, and valve (III) and valve (a) are closed.Humid air (9) in the hothouse is located to discharge by valve (b) through valve (I) through the suction of heat pump blower fan at this moment.It is very big that this kind operating mode is used for dry indoor air humidity, and the situation of heat pump refrigerating quantity not sufficient, as the initial stage of timber drying.
