る。 Next, the operation of the grain drying dry air generator 1 having the above structure will be explained. It is well known that the higher the evaporation temperature of the refrigerant in the evaporator 9 and the lower the condensation temperature of the refrigerant in the condenser 10, the better the coefficient of performance of the heat pump is. Therefore, let us consider the coefficient of performance of the dry air energy generator 1 for drying grains according to the present invention.
First, the blower 13 is activated and outside air is sent into the evaporator 9 from the inlet 2. When the cooling capacity of the evaporator 9 is qKcal/H, it is expressed as q=Cp(T- T1 ) Q1 + C1 (x-x) Q1- (1)= qS + qL . At this time, C p : Specific heat of constant volume = 0.24 Kcal/Kg°C C 1 : Latent heat of vaporization = 596 Kcal/Kg°C T: Outside air temperature (dry bulb) °C T 1 : Temperature of air cooled by the evaporator °C x: Absolute of outside air Humidity Kg/Kg′ x 1 : Absolute humidity Kg/ of the air cooled by the evaporator
Kg′ Q 1 : Amount of air passing through the evaporator Kg′/H q S : Sensible heat when the outside air temperature T drops to the cooling temperature T 1 q L : Latent heat when dehumidifying by the evaporator In equation (1), , if the cooling capacity q is constant and the air amount Q 1 is increased, (T-T 1 ) and (x-x 1 ) become smaller because C p and C 1 are constant. However, when (T-T 1 ) and (x-x 1 ) become smaller, T 1 =
T D , x=x 1 , and no dehumidification occurs, so the purpose of lowering absolute humidity is lost. However, T D is the dew point temperature of the outside air. Therefore, by adjusting the adjustment damper 7 within the range where T 1 < T D and increasing the air amount Q 1 , (T - T 1 ) becomes smaller, that is, the refrigerant The evaporator 9 can be operated at a higher evaporation temperature.
次に凝縮器１０が空気に与える熱量をqCとする

のである。 Next, if the amount of heat given to the air by the condenser 10 is q C , then q C = C p (T 2 − T 1 ) Q 1 + C p (T 2 − T) Q 2 −(2) = q c1 + q c2 . expressed. At this time, T 2 : Temperature of the air heated after passing through the condenser (°C) q c1 : Amount of heat used to heat the air passed through the evaporator q c2 : Amount of heat used to heat the secondary air from the air intake hole Q 2 : Amount of secondary air from the air intake hole Kg'/H In equation (2), the amount of heat given to the air from the condenser 10 q C is the amount of heat that heats the secondary air Q 2 from just before the condenser 10 It is the sum of q C2 and the amount of heat q C1 that heats the air Q 1 that has passed through the evaporator. Therefore, in the case of the present invention,
The condenser 10 can be operated with the refrigerant condensing temperature lower by the amount of heat q C2 used to heat the secondary air than in the conventional system.

れて所望の乾燥空気が得られる。 By the above-described operation, in order to obtain the desired dry air, the electric signal corresponding to the humidity detected by the humidity sensor 14 is compared with the humidity indicated by the humidity setting device 16, and the comparison value and the opening of the adjustment damper 7 are compared. By setting the degree in advance, the amount of secondary air can be adjusted. Furthermore, when the desired dry air cannot be obtained even if secondary air is taken in, the electrical signal from the humidity sensor 14 is compared with the humidity indicated by the humidity setting device 16,
By applying the signal to the inverter 17, the corresponding rotational speed of the compressor 11 is controlled to obtain the desired dry air.
次に、送風される乾燥空気の湿度について述べ
る。凝縮器１０を通過して、加温された乾燥空気
の絶対湿度をx2、送風される乾燥空気量をＱとす
れば、前述したｘ，x1，Q1，Q2を参照して、
x2＝x1×Q1／Ｑ＋ｘ×Q2／Ｑ −(3)
の関係が得られる。但し、Ｑ＝Q1＋Q2(3)式から
x1＜ｘであるから、x2＜ｘとなつて、当然ながら
外気の絶対湿度よりも低下した絶対湿度の乾燥空
気を発生できるのである。 Next, the humidity of the blown dry air will be described. If the absolute humidity of the heated dry air passing through the condenser 10 is x 2 and the amount of dry air blown is Q, then with reference to x, x 1 , Q 1 , and Q 2 described above, The following relationship is obtained: x 2 =x 1 ×Q 1 /Q+x×Q 2 /Q − (3). However, from equation (3), Q=Q 1 +Q 2
Since x 1 <x, x 2 <x, which naturally makes it possible to generate dry air with an absolute humidity lower than that of the outside air.

る。 In this way, by taking in the secondary air from immediately before the condenser 10, the evaporation temperature of the refrigerant in the evaporator 9 becomes high, and the condensation temperature of the refrigerant in the condenser 10 becomes low. As is clear from the well-known coefficient of performance curve shown in FIG. It can be made higher.
