Description

All-weather hybrid pump system

The present invention relates to an all-weather hybrid heat pump system using air heat source, solar heat, geothermal heat, ambient waste heat, and latent heat in the air. More specifically, the outdoor air temperature decrease due to snowfall and rainfall, and the lack of air heat source and sudden low temperature during winter (subzero 20) It is possible to operate high efficiency, high performance cold, hot water / cooling and heating at the same time as a single facility consisting of 3 cycle circuits by mixing 7 heat sources even under bad conditions such as below). The present invention relates to an environmentally friendly and energy-saving heat pump system with free operation options.

In general, heat pumps raise heat from a low temperature to a high temperature, that is, they absorb heat from low-temperature heat sources such as air, water, geothermal, and ambient heat, and thus they are used as advanced energy for cooling, heating, hot water supply, and process. It is an eco-friendly non-combustion-type energy-free combustor that was first developed for evaporating compressed refrigerants such as refrigerators, freezers, and air conditioners to take away the surrounding heat, but is now a low-temperature heat source using heat generated from the refrigerant or heat of condensation. It is used to encompass a cooling device that delivers high temperature to a high temperature, a heating device that delivers a high temperature heat source to a low temperature, and a combined use of an air conditioning and heating device. ), Geothermal source, etc.

In addition, according to the heat supply method, it is divided into heating, cooling, dehumidification, and heating and cooling according to the range of use of hot air, cold air and hot water, cold water, and pump.

The principle of operation is to repeat the cycle of evaporating the high-pressure and high-pressure compressed refrigerant from the compressor and sending it to the condenser in the case of heating. The system is configured so that the evaporator acts as a condenser so that the condensed refrigerant exchanges heat with the hot outside air to cool the target point to be cooled.

Currently, most heat pumps are composed of both cooling and heating. In general, when the external temperature is less than 5 ℃, the performance deteriorates and mechanical damages occur and the operation is not smooth. On the other hand, Geothermal energy is attracting attention as a new heat pump to replace air heat source because it can continuously supply heat in harsh areas and has high energy efficiency.

The conventional heat pump system is disclosed in Patent Registration No. 10-0586460 (Hybrid Heat Pump System using solar heat and air heat), No. 10-0574418 (Heat Pump System), and No. 10-0580277 (Heat and Pump Heat / .

The conventional heat pump systems described above have a low temperature heat source (especially below minus 8 degrees in winter) and a lack of air heat sources in the atmosphere due to rainfall or snowfall, which causes frost on the surface of the evaporator. There is a problem that the energy consumption is increased rather than energy saving due to the inability to operate the cooling to stop the heating for about 10 minutes periodically.

       Therefore, the present invention was created for the purpose of solving the above-mentioned problems, including air heat in the atmosphere, solar heat, geothermal heat, waste heat, and the like, by mixing the hot gas heat of the system itself with the hot water of the heat storage tank to obtain an intake temperature control. By maintaining constant gas pressure formation and mixing waste heat, latent heat, and solar heat source of surrounding facilities, it enables normal operation with high efficiency and high performance in any harsh environment.In hot water and heating, the evaporator consists of air heat and hybrid in parallel, cold water, When cooling, the air evaporator is converted to an air condenser. At the time of cooling, the hybrid circuit is formed so as to provide a heat pump system capable of high efficiency, high performance cooling, hot water, cooling and heating.

The present invention in the compressor through the four-way valve, water evaporation, combined condensation heat exchanger, combined air-cooled evaporation, condensation heat exchanger, liquid separator equipped with a gas temperature sensor and low pressure switch, hybrid heat exchanger, waste, latent heat exchanger and hot gas condensation, evaporation Pipe to be connected to the heat exchanger, expansion valve and check valve is installed on the pipe connected to the condensation, evaporative heat exchanger and receiver tank in the water evaporation, condensation combined heat exchanger, cold on the pipe connected to the combined cold, hot water tank , The hot water mixing valve, the cold and hot water pump and the water solenoid valve are installed, and the cooling and heating air conditioner in the combined cold and hot water tank, underground floor heating and cooling on the pipe for supplying cold and hot water to indoor cooling and heating , Hot water purification tank (spiral tank) and cold, hot water circulation pump is installed, the solar water heater, small beam through the hybrid circulation pump in the hybrid heat exchanger And a hybrid tank connected to the air and geothermal power, the upper pipe of the air-cooled combined evaporation and condensation heat exchanger is connected to the expansion valve during evaporation and the check valve when condensation, and the receiver tank is a hybrid heat exchanger, waste, latent heat exchanger and air-cooled It is characterized in that the pipe is connected to the combined evaporation, condensation heat exchanger.

Therefore, the present invention is a mixture of air heat, solar heat, geothermal heat, latent heat in the air, the normal operation of high efficiency, high performance without deterioration of the system even if the air heat in the air due to extreme weather or less than 20 degrees below the extreme cold weather and rain or snow It is capable of cooling and heating by producing cold water and hot water. Therefore, the scope of application is wide regardless of the building size, and the facilities, housing, industrial and industrial areas with large amounts of hot water use such as central heating, heating, hot water facility cultivation, and livestock industry. It can be applied to the field, and it is possible to provide a pleasant environment from pollution and pollution because there is no carbon emission gas because it can use cold, hot water, cooling and heating as a single system and uses natural energy.

When the water inlet temperature is low, the pressure of the high pressure gas decreases the evaporation and the cold and hot water combined tank 900. By reducing the hot water temperature of the regenerated hot water to prevent the phenomenon of lowering the heat of the tank, hot water heating is supplied in a constant amount in a large amount of the temperature required in the field of business.
