Abstract

PURPOSE:To markedly improve an air flow velocity distribution for a heat exchanger and contrive enhancement of the cooling capability of a main body by a construction wherein a first evaporator and a first condenser which have smaller widths are disposed on the side nearer to cross flow fans. CONSTITUTION:Each of an evaporator 6 and a condenser 13 is constituted of a finned tube type heat exchanger with a small fin width S, and is split into two in a row direction. First heat exchangers 6a, 13a on the downstream side are made to have widths greater than the widths of second heat exchangers 6b, 13b on the upstream side, and the downstream-side heat exchangers 6a, 13a are disposed on the side nearer to cross flow fans 5, 12 so that large spacings can be provided between curved parts 4a, 4g of a fan casing 4 and the upstream-side heat exchangers 6b, 13b.

11 is an indoor air outlet. Inside the second chamber 3,
An outdoor cross-flow fan 12 disposed inside the second curved portion 4b of the fan casing 4, a condenser 13, an outdoor stabilizer 14, which constitutes a well-known refrigeration cycle,
is provided and communicates with the outdoor side suction port 15 and the outdoor side Suita port 16. Further, the condenser 13 is connected to the air conditioner main body 1
One end is attached at a predetermined angle (α) to the back surface of the condenser 13, and a rotary disk 1 is mounted on the windward side and below the condenser 13.
An evaporator 19 is provided, which comprises a motor 7 and a motor 18, and scatters condensed water generated in the evaporator 6 toward the condenser 13.

Problem to be Solved by the Invention However, in the above configuration, the curved portions 4g and 4b of the fan casing 4 are close to the far sides 6m and 13m of the crossflow fans 5 and 12 of the evaporator 6 and condenser 13. Because of this, the wind speed distribution in the evaporator 6 and condenser 13 is poor.
Air mainly flows only through the heat exchanger parts 6b, 13b on the side closer to the cross-flow fan 5.12, and not much air flows through the heat exchanger parts 6a, 13a on the far side. Further, in the condenser 13, the condensed water generated in the evaporator 6 is transferred to the heat exchanger portion 13a near the fan casing curved portion 4a of the condenser 13 by the evaporator 19 located on the windward side and below the condenser 13. The wind speed distribution was getting even worse. For this reason, in the conventional configuration, the efficiency of the heat exchanger was poor, and there was a problem that the cooling capacity of the main body could not be increased in spite of the amount of material input for the heat exchanger.

In view of the above problems, the present invention provides an air signing machine that can significantly improve the air velocity distribution of the heat exchanger, improve the cooling capacity of the main body, and reduce the material cost of the heat exchanger. It is.

Means for Solving the Problems The means of the present invention for solving the problems described above includes an evaporator and a condenser, a first evaporator and a first condenser each having a predetermined width dimension,
Consisting of a second evaporator and a second condenser that are arranged in parallel with each of the first evaporators and condensers and have a width dimension larger than that of each of the first evaporators and condensers, Each of the above first
In the second chamber, the first evaporator and the first condenser are arranged near the cross-flow fan.

Effect The present invention reduces the ventilation resistance of the first heat exchanger located on the side farther from the cross flow fan by the above-described structure,
It is possible to make the air velocity distribution of the heat exchanger uniform. As a result, the efficiency of the heat exchanger is increased, and the material cost of the heat exchanger can be reduced while improving the cooling capacity of the main body.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

In the figure, 1 indicates the main body of the air conditioner, 2 indicates the first chamber (indoor wind circuit), a indicates the second chamber (outdoor wind circuit), and 4 indicates the first chamber 2 and the second chamber 3. It is a fan casing that partitions. 5 is an indoor cross-flow fan disposed inside the first curved portion 4m of the first chamber 2, 6 is an evaporator constituting a well-known refrigeration cycle, 7 is an indoor stabilizer, 8 is an air filter, and 9 is an Front grill, 10 is indoor air intake, 11
is the indoor air outlet. Inside the second chamber 3 of iii.
An outdoor cross-flow fan 12 disposed inside the second curved portion 4b of the fan casing 4, a condenser 13 and an outdoor stabilizer 14 constituting a well-known refrigeration cycle are provided. It communicates with the outer air outlet 16. The condenser 13 is attached from one end to the back surface of the air conditioner main body 1 at a predetermined angle (α),
On the windward side and below the condenser 13, a rotating disk 17 is provided.
An evaporator 19 is provided, which includes a motor 18 and a motor 18, and scatters condensed water generated in the evaporator 6 toward the condenser 13. Furthermore, the evaporator 6 and the condenser 13 are constructed of fin-tube heat exchangers with a small fin width S, and are divided into two in the row direction, with the first heat exchanger on the downstream side having a width of 6 m and a width of 13a. the second heat exchanger 6b, 13 on the upstream side
a first heat exchanger Sm on the downstream side, which is shorter than the width of b;
13a is provided on the side closer to the cross-flow fan 5.12, so that the distance between the curved portions 4a, 4b of the fan casing 4 and the upstream heat exchangers 6b, 13b can be increased. Further, 6G in the figure is a return bend of the evaporator 6 provided inside the first chamber 2.

Effects of the Invention As described above, the present invention provides first evaporators and condensers with small width dimensions on the side near the cross flow fan, and furthermore, the condenser is installed at one end on the back side of the air conditioner. The configuration in which the heat exchanger is mounted at an angle can reduce the ventilation resistance of the heat exchanger on the side farther from the crossflow fan, and can even out the air velocity distribution of the heat exchanger. Further, by making the air velocity distribution of the heat exchanger uniform, the efficiency of the heat exchanger is increased, and the material cost of the heat exchanger can be reduced while improving the cooling capacity of the main body. Furthermore, in the heat exchanger, a return bend of the downstream heat exchanger,
Since the lead pipe is inside the indoor wind circuit, the return bend and heat exchange ability from the lead pipe are also improved.
It has various advantages.
