Abstract

A cooling and heating energy saving system includes a cooling and heating device, a data center, a boiler, a heat exchanger, and a circulating pump. The boiler receives waste heat of the data center and heat generated by the cooling and heating device, and then generates high-temperature heat and transfers the high-temperature heat to an indoor heating device. The heat exchanger receives heat from the cooling and heating device and the data center. The circulating pump receives the heat generated by the data center and transmits the heat to an outdoor cold source, and further transmits the outdoor cold source to an indoor device through the heat exchanger.

First claim

What is claimed is:

1. A cooling and heating energy saving system comprising:
a cooling and heating device for performing indoor cooling and heating;
a data center generating heat when turned on to operate;
a boiler coupled to the cooling and heating device and the data center, the boiler being configured to receive heat energy including waste heat of the data center and heat generated by the cooling and heating device, and transfer the heat energy to a reheater or a floor;
a heat exchanger coupled to the cooling and heating device and the data center, the heat exchanger being configured to receive heat from the cooling and heating device and the data center; and
a circulating pump coupled to the data center, an outdoor cold source, and the heat exchanger, the circulating pump being configured to receive the heat generated by the data center and transmit the heat to the outdoor cold source for heat dissipation, the circulating pump being further configured to transmit the outdoor cold source to an indoor device through the heat exchanger.

2. The cooling and heating energy saving system of claim 1 , wherein:
the cooling and heating device comprises a heating component and a cooling component;
the boiler and the heat exchanger receive heat generated by the heating component; and
the cooling component is configured to transmit a cold source to an indoor cooling device.

3. The cooling and heating energy saving system of claim 1 , wherein:
the heat exchanger is further configured to transmit the heat from the heating and cooling device and the data center to the indoor device.

4. The cooling and heating energy saving system of claim 2 , wherein:
the heat exchanger is further configured to transmit the heat from the heating and cooling device and the data center to the indoor device.

5. The cooling and heating energy saving system of claim 3 , wherein:
the indoor device is a chilling beam or blower.

6. The cooling and heating energy saving system of claim 2 , wherein:
the heating component is a heat pump.

7. The cooling and heating energy saving system of claim 6 , wherein:
the cooling component is a chiller.

8. The cooling and heating energy saving system of claim 7 , wherein:
the chiller is a water-cooled chiller.
