Embodiment 1

[0036] Example 1: The location of the cold and heat source of the hospital building and its system

[0037] The cold and heat source integrated unit of the present invention is particularly suitable for hospital buildings. Modern hospitals require the entire building to be environmentally controlled, requiring a large amount of air-conditioning chilled water and hot water. But now the amount of steam needed for sterilization is getting less and less, and the quality requirements are getting higher and higher. High-quality steam is often supplied on-site by the sterilization system, instead of relying on the steam system.

[0038] The integrated cold and heat source unit of the present invention replaces a large chiller and a boiler to become a centralized cold and heat source in a hospital, which is installed on the roof. Through the pipeline well, the hot end of the cold and heat source integrated unit is connected to the heating system, and the cold end is connected to the chill...

Embodiment 2

[0041] Example 2: The location of the hotel building's cold and heat source and its system

[0042] The integrated heat and cold source unit is also suitable for large hotel buildings. The integrated cold and heat source unit will replace the large chiller and boiler to become the centralized cold and heat source of the hotel building, which is installed on the roof. Through the pipeline well, the hot end of the cold and heat source integrated unit is connected to the heating system, and the cold end is connected to the chilled water supply system, which provides heating and cooling at the same time throughout the year, which is called a four-pipe system. The integrated cold and heat source unit supplies 7°C chilled water that can meet the needs of air conditioning throughout the year, and at the same time can provide a large amount of 55°C hot water for bathing. In addition to requiring a lot of hot water for bathing, hotel buildings are also becoming larger and larger like moder...

Abstract

The invention relates to a cold / heat source integrated unit. The outlet of a compressor is respectively connected with an air-cooled condenser and a water-cooled condenser, the air-cooled condenser and the water-cooled condenser are jointed and then connected with a throttle device which is respectively connected with an air-cooled evaporator and a water-cooled evaporator, the air-cooled evaporator and the water-cooled evaporator are jointed and then connected with the inlet of the compressor, the outlet of the water-cooled evaporator is connected with the inlet of a cooling water user terminal, the outlet of the cooling water user terminal is circularly connected with the water-cooled condenser, the outlet of the water-cooled evaporator is connected with the inlet of a hot water user terminal, and the outlet of the hot water user terminal is circularly connected with the water-cooled evaporator. The invention changes the control target which traditionally is a specific space in a building into the control target which is the whole building, comprehensively plans the supply of a cold source and a heat source of the whole building, balances the cold energy and the heat energy, reduces the discharge of waste heat or waste cold, reduces the consumption of unrenewable resources to the minimum and forms a comprehensive energy-saving system.

Description

Technical field [0001] The invention relates to the technical field of heating, ventilation and air conditioning engineering, in particular to a cold and heat source integrated unit that utilizes the principle of energy transfer and is comprehensively utilized. Background technique [0002] At present, the traditional cold and heat sources of public buildings are mostly a combination of compression refrigeration units and steam boilers, and the cold and heat sources respectively supply the refrigerant and heat medium required by each functional space in the entire building. This traditional cold source emits considerable waste heat while consuming electric energy to output chilled water, which is discharged outdoors. The same heat source consumes fossil fuels to output steam while discharging high-temperature flue gas and condensate. This shows that the traditional concepts of cold and heat sources are always consuming energy and generating waste heat. This kind of cold source ca...
