Description

Air Conditioner Using Gas Heat Pump {Air Conditioner using Gas Heat Pump}

The present invention relates to an air conditioner using a GHP, and more particularly, to a device capable of intensively heating and cooling a large-scale facility by generating a cold or warm air without using a cooling tower using a gas heat pump.

In general, a cooling and heating system includes a system for cooling and heating by using a cooling / hot water unit and a cooling tower to send the cooling / hot water produced in the unit to an air conditioner or a coil unit through a pipe.

FIG. 2 schematically illustrates a conventional heating and cooling air conditioning system using a cooling tower, and illustrates a state in which cold air or warm air generated from an air conditioner 2 is supplied through a duct 3 installed indoors.

The air conditioner is connected to the cold and hot water unit 4, and the cold and hot water unit 4 is shown the cooling tower (5) is installed.

Inside the cold and hot water unit, refrigerant is stored and circulated to make cold water, and hot water is produced by a burner using light oil or gas as a fuel.

When this water is pumped to the air conditioner coil (not shown) and the air conditioner (not shown) installed inside the air conditioner is installed, cold and hot wind is sent to the place where it wants to cool and heat through the duct. If you want to use the coil unit in the air, cool and hot water produced by the cold and hot water unit can be sent to the coil installed inside the coil unit and blown with a small fan to cool and heat.

In this case, a cooling tower is separately installed to cool the heat generated by the cold / hot water unit.

Advantages of the conventional air conditioner or coil coil unit system, such as through the duct has the advantage that intensive cooling and heating is possible.

However, the disadvantage of the conventional air conditioner or coil coil unit system is that the machine room to be installed, such as cold and hot water units, cooling towers.

In detail, in order to use such a system, complicated piping must be installed inside the machine room.

In addition, there is a need for a device to send the cold and hot water produced in the cold / hot water unit, and each piping equipment is required to send it to the air conditioner and the coil unit.

In addition, since water is delivered to the coil along the pipe and circulated, there is a fear of coil freezing of the winter pipe and the air conditioner.

In addition, the efficiency of cooling and heating decreases due to the temperature change of water in the process of being delivered to the coil of the air conditioner and the coil unit along the pipe.

Therefore, it is difficult to individually cool and heat a number of places, and thus it is not possible to use as much energy as necessary, which is a waste of energy.

An air conditioning system made in a manner different from that described above includes a system using a gas heat pump (GHP).

It is called gas heat pump. Unlike general cooling and heating system, it is a system that can compress and cool refrigerant by force of engine in outdoor unit equipped with gas engine to force cooling and heating.

3 shows a conventional heating / cooling system diagram using a GHP, which includes an indoor unit 6 installed indoors and an outdoor unit 1 connected thereto. The outdoor unit includes a radiator 13 and a GHP 11 connected to the radiator. And the engine 12 for operating the GHP.

The figure shows the cooling (summer) and heating (winter) operation degree according to the operating conditions.

At the time of heating, the engine cooling water (hot water) generated by the engine operating the GHP may heat the refrigerant of the outdoor exchanger to increase the heating effect.

Unlike the system that circulates water by using a cooling and hot water unit cooling tower, the above system can think of the method of air conditioner that we generally use by cooling the refrigerant directly to the indoor unit (air conditioning unit). In contrast to the circulation method, the refrigerant is rotated and heated.

The indoor unit (air-conditioning unit) is also equipped with a coil (not shown), and the refrigerant sent from the outdoor unit circulates and blows it to the wind to produce cold and hot wind.

The advantage of the air conditioning system using the GHP is the advantage that the machine room that must be installed, such as cooling and hot water unit cooling tower, and

The advantage of not having to install complicated piping inside the machine room,

There is no need to send the cold and hot water produced in the cold and hot water units, and there is no need for the plumbing equipment to send it to the air conditioner and the coil unit. Refrigerant is delivered to the coil directly along the pipe and circulated, so there is no fear of freezing of the coil in the winter refrigerant pipe and the indoor unit.

There is no change in the temperature of the refrigerant in the process of being delivered to the indoor unit (air conditioning unit) coil along the pipe, so the efficiency of cooling and heating can be increased.

Since it is easy to individually cool and heat a number of places, there is an advantage that it is possible to prevent waste of energy by using as much energy as necessary.

As a disadvantage of the air conditioning system using the GHP, there is a disadvantage in that it is not easy where intensive cooling and heating are required.

Since each refrigerant pipe must be connected to the indoor unit, a large number of indoor units are required for cooling and heating in a large place, and thus there is a disadvantage in that the installation cost and management cost are high.

The purpose of the present invention for solving the above problems is applied to a place where intensive cooling and heating is required in a wide place by combining a GHP outdoor unit and a conventional air conditioner,

By eliminating the cold / hot water unit and cooling tower from the existing equipment, it reduces unnecessary building area, eliminates the complicated piping, and eliminates the concern about freezing of the air conditioner due to the use of coolant for water. Therefore, there is no need for each refrigerant pipe and indoor unit to provide a cooling and heating device that can be expected to reduce the cost effect.

The object of the present invention as described above is achieved by providing a device for cooling and heating through the duct by sending the refrigerant circulated directly in the GHP to the coil of the air conditioner.

To the refrigerant liquid.

At the time of heating, it performs in the opposite way to the above.

In addition, during heating, the engine cooling water (hot water) generated by the engine operating the GHP is configured to operate by increasing the heating effect by heating the refrigerant of the outdoor exchanger.
