, cold tofu controller 3, evaporator 4, and compressor 1 in this order.

On the other hand, the air is cooled and moisture-resistant as it passes through the evaporator 4, heated in the indoor condenser 7 to become dry air, and is then heated by the blower F.
is supplied indoors. In this dehumidifying dryer, the high pressure refrigerant gas discharged from the compressor 1 is first passed through the outdoor condenser 6, so that the heat of condensation is released outdoors 1, and when the temperature is low, the indoor side is in cooling operation. . In addition, when the cooling and dehumidifying load at medium to high temperatures is quite large, the outdoor condenser fan 1
, 1/ are stopped, the exhaust heat from the indoor 11 tl condenser is small, and the amount of indoor heated liquid is small. Furthermore, when operating a single fan installed outdoors, when the relative humidity is low (60 to 70 degrees Fahrenheit or less), it goes into cooling operation. In other words, # because the assembly capacity is large and the low-temperature operation limit temperature m- is high, when the temperature is as low as +0'C or below (d normal operation cannot be performed, normal operation is possible Z), the first Similar to the dehumidifying dryer shown in the figure, indoor air is heated by a heater 5.

In the figure, 1(' indicates a cabinet that houses the outdoor 11 (II m condenser 6 and its fan il/).

As mentioned above, the conventional dehumidifying dryer shown in Figs. 1 and 2 requires a heater 5 using a separate heat source for normal operation at low temperatures, which has the disadvantage of increasing equipment and operating costs. Ta.

[Purpose of the invention]

An object of the present invention is to provide a dehumidifying dryer that enables normal operation at low temperatures without using a heater sound from a separate heat source by effectively using condensed waste heat A-u, and reduces equipment costs and operating costs. It's about doing.

[Summary of invention O]

To achieve this objective, the present invention comprises:) E condenser, condenser, refrigerant? Equipped with a refrigeration cycle consisting of a 1JII controller, an evaporator, etc. After cooling and dehumidifying the air with the evaporator,
In a dehumidifying dryer that uses condensation heat from the condenser,
An intermediate refrigerant port is provided between the refrigerant inlet of the condenser and the refrigerant 81 port, and the intermediate refrigerant port is connected to the discharge side system of the compressor via an on-off valve, and the on-off valve is operated only during low temperature operation. When the opening/closing valve opens, refrigerant gas from the compressor flows into the condenser from the intermediate refrigerant section.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to FIG. 4). The figure shows a refrigeration cycle diagram of a dehumidifying dryer according to the present invention, which is equipped with a refrigeration cycle having an indoor III condenser condenser outdoor 1111 # contraction amount, and the same reference numerals as in Fig. 2 are the same,
If so, please show the equivalent number 17. The indoor #compressor 7 has an intermediate refrigerant lower C between its refrigerant intake lower A and refrigerant lower B. This D intermediate refrigerant entry lower C is connected to the discharge pipe of the compressor 1 via an electromagnetic on-off valve 8. The 8 electromagnetic on-off valves are opened only when the temperature is low to allow cylinder temperature and high pressure refrigerant gas to flow from the intermediate refrigerant IC into the room.

On the other hand, the rotational speed of the outdoor condenser fan Pl/ is controlled by a room temperature detector (not shown) that detects the room temperature when the temperature is medium to high.
That is, it is possible to control condensation and control the rise in room temperature. Also, when the temperature is high, the inner condenser 7
The rotation speed is controlled by a detector 9 installed in the middle of the refrigerant pipe from the refrigerant pipe to the outdoor condenser 6, that is, the refrigerant temperature (refrigerant pressure) in the refrigerant pipe is set before the detector 9 is set. When the temperature exceeds 1i1i, the outdoor condenser fan F' starts operating and its rotational speed is controlled in proportion to the refrigerant temperature (or refrigerant pressure), so that room temperature control can be performed.

Further, it is housed in the outdoor condenser 6 and the respective fans F'rj, Gabineso, and I-K.

Next, explain the operation of the present invention +), the G medium is transferred to the compressor 1, indoor 111, condenser 7, outdoor 11111 @ condenser 6, liquid receiver 101, medium controller 3, evaporator 4, compressor ( Number 1
I will leave you in that order. On the other hand, after the air is cooled and dehumidified in the evaporator 4, the refrigerant gas is cooled in the indoor EBB device 7, and at this time, the heat of the refrigerant gas is absorbed and becomes high-temperature dry air. The acorns are poured into the room.

In addition, when the refrigeration cycle cannot operate normally at low temperatures, the electromagnetic on-off valve 8 opens, and the high temperature cylindrical pressure refrigerant gas from the compressor 1 flows from the intermediate refrigerant input lower C into the outdoor condenser, and the condenser enters the condenser. Since the refrigerating cycle is such that the refrigerant is condensed in step 7 and taken out as a refrigerant liquid from the refrigerant lower B, low-temperature operation can be performed without using a conventional heater. When the temperature is medium to high, the electromagnetic on-off valve 8 closes and the high-temperature, high-pressure refrigerant waste from the compressor 1 is supplied from the refrigerant lower A to the indoor condenser 7, so the condenser 7 is used with a large capacity. be done.

Therefore, from low temperature (about 5°C) to high temperature (60°C 8 degrees)
It is possible to perform dehumidification rituals that utilize condensed waste heat throughout the entire process, significantly reducing equipment costs and operating costs.

In addition, in this embodiment, the outdoor condenser fan k”rr
The rotation speed is controlled by a room temperature detector at medium and high temperatures.
Moreover, since the temperature is controlled by the detector 9 @ 11 when the temperature is at a madder temperature, the temperature rise can be controlled. Since each component of the refrigeration cycle that houses the outdoor condenser 6 and its fan F' is built into the same cabinet, the outdoor condenser 6 and - are connected to the - fan F' as shown in Fig. 2. Compared to conventional dehumidifying dryers, which are housed in separate cabinets, installation work can be simplified, refrigerant piping work can be saved, the installation area can be reduced, and maintenance can be performed in the same location.

Although this embodiment shows an example of a dehumidifying dryer equipped with a refrigeration cycle having an indoor 948 condenser 7 and an outdoor condenser 6, a dehumidifying dryer equipped with a refrigeration cycle having one condenser may also be used. Of course, the effect of low-temperature operation can be achieved without the need for a heater.

〔Effect of the invention〕

As described above, according to the present invention, normal operation can be performed at low temperatures without using a heater as a side heat source, so equipment costs and operating costs can be reduced.
