A fan(50) is installed in the plate-fin. The air cooling or the water cooling operation can be possible at the same time by passing the air between the plate-fins. The hot water of a hot water storage tank has the heat exchange with the cooling water through a heat exchanger to be reused for the hot water.

Description

CONDENSER TOGETHER WITH WATER COOLING AND OR WIND COOLING}

The present invention relates to a condenser when cooling a heat pump type air conditioner, and in particular, a double pipe structure in which a cooling water pipe is inserted into a refrigerant pipe, and a plate 50 is fused on the outside of the refrigerant pipe and a fan 50 for forced ventilation is installed therein. As a cooling condenser designed to be used for both air-cooled and water-cooled, the refrigerant vapor inlet 10 and the cooling outlet 30 form one end, and the refrigerant liquid outlet 20 and the cooling inlet 40 are located at opposite ends. The double-pipe structure in which the cooling water pipes are located, and the heat pump type is reused by reusing the waste heat of the air-cooled or water-cooled condenser, which has been a problem in the prior art, by using hot water that obtains this amount of heat by supplying the amount of heat required to change the refrigerant vapor to the refrigerant liquid. It improves the heat efficiency of the air conditioner and plays it fused to the outside of the refrigerant pipe when it is impossible to remove calories with cooling water. As pure air-cooled condenser to remove heat from the pin (60) relates to a condenser of the heat pump type Cooling & Heating to talk to the stability in operating the conversion possible uses.

In general, the heat pump air conditioner is installed as an air-cooled or water-cooled condenser, and in order to ensure the stability of operation in such a condenser, a separate condenser is disposed when the heat generated from the condenser is discarded or reused. This conventional technology is not only inefficient by treating the heat of the condenser waste, but also has a problem of significantly lowering the cooling efficiency when the temperature of the cooling water is increased in the external air or water cooling in the air-cooled type, and inefficiency and stability of the equipment if a separate condenser is placed.

The present invention has been made to solve the above problems,

An object of the present invention is a double condenser structure in which a coolant pipe is inserted into a refrigerant condenser in a cooling condenser designed to enable water-cooled and air-cooled operation respectively or simultaneously, and a plate fin 60 is fused and forced to the outside of the refrigerant pipe. It is equipped with a fan 50 for ventilation and the refrigerant vapor inlet 10 and the cooling outlet 30 form one end, and the refrigerant liquid outlet 20 and the cooling water inlet 40 are located at opposite ends, so that the cooling water pipe is in the refrigerant pipe. This double pipe structure is located in the cooling water and the amount of heat required to change the refrigerant vapor to the coolant liquid by using the hot water obtained this heat economy is very economical and cooling operation is possible without affecting the restriction of the hot water efficiency and stability is very Provides excellent heat pump type air conditioner and air conditioner. Compared to the air-cooled condenser to the cross sectional area of the refrigerant over the refrigerant pipe of the refrigerant pipe it provides excellent cooling efficiency wide.

The condenser according to the present invention for achieving the above object is a double pipe structure in which the cooling water pipe is inserted into the refrigerant pipe and the plate fin 60 is fused on the outside of the refrigerant pipe and the air is cooled by mounting a fan 50 for forced ventilation. And a refrigerant vapor inlet 10 and a cooling outlet 30 having one end, and a refrigerant liquid outlet 20 and a cooling inlet 40 which are located at opposite ends as cooling condensers designed to be combined with water-cooling. It is characterized by the use of hot water that obtains this amount of heat by giving the cooling water the amount of heat required to change the refrigerant vapor into the refrigerant liquid by forming a double pipe structure in which the cooling water pipe is located.

On the other hand, the refrigerant vapor inlet 11 and the refrigerant liquid outlet 21 are additionally configured to configure each component of the above components except the fan 50 in a stacked form for cooling capacity, stable operation, and efficient use of the space area. A refrigerant pipe is installed, and a cooling water pipe consisting of a cooling water inlet 41 and a cooling water outlet 31 is installed to connect in parallel with the existing refrigerant pipe and the cooling water pipe, and the wind generated from the fan 50 passes through the condenser of the laminated structure. I can make it to form.

It will be described below in more detail for the practice of the invention.

As described above, the combined air and water-cooled condenser according to the present invention improves the problem of generation of condensation waste heat, which has been a problem in the prior art, and a problem of lowering the cooling efficiency when the external temperature is high. By reusing, the efficiency and economic efficiency of the air conditioner are greatly improved.

On the other hand, when the amount of hot water used is small, air cooling is possible at the same time when the temperature of the coolant is out of the proper operating range, and even when the use of hot water is stopped, it is possible to operate with a pure air-cooled condenser so that stable operation is possible.

Hereinafter, the present invention will be described in more detail with reference to <FIG. 1>, <FIG. 2>, and <FIG. 3> of the embodiment of the air-cooled and water-cooled combined condenser.

In a heat pump type air conditioner or a combined air-conditioning unit, a single condenser enables air cooling and water cooling to increase the efficiency, operational stability, and economic efficiency of the condenser. As shown in FIG. And the plate fin 60 is fused to the refrigerant pipe surface and the fan 50 has a structure to remove the required amount of heat by forcing the wind passing between the plate fin 60.

In order to reuse the amount of heat obtained from the cooling water, a storage tank 70 is installed as shown in FIG. 2, and the cooling water circulated by the storage water and the cooling water circulation pump supplied by the storage water circulation pump 90 in the hot water heat exchanger. Heat exchange between them to make the hot water into hot water.
