Embodiment 1

[0036] Example 1: Places of cold and heat sources and their systems in hospital buildings

[0037] The cold and heat source integrated unit of the present invention is particularly suitable for hospital buildings. Modern hospitals require environmental control of the entire building, requiring a large amount of air-conditioned chilled water and hot water. Now, the amount of steam required for sterilization is less and less, and the quality requirements are getting higher and higher. High-quality steam is often supplied by sterilization on site, no longer by the steam system.

[0038] The cold and heat source integrated unit of the present invention replaces the large chiller and the boiler, and becomes the centralized cold and heat source of the hospital, which is installed on the roof. Through the pipeline well, the hot side of the integrated cold and heat source unit is connected to the heating system, and the cold side is connected to the chilled water system, which provi...

Embodiment 2

[0041] Example 2: Locations of cold and heat sources and their systems in hotel buildings

[0042] The integrated cooling and heating unit is also suitable for large hotel buildings. The cold and heat source integrated unit replaces the large chiller and boiler, and becomes the centralized cold and heat source of the hotel building, which is installed on the roof. Through the pipeline well, the hot side of the integrated cold and heat source unit is connected to the heating system, and the cold side is connected to the chilled water system, which provides both heating and cooling throughout the year, which is called a four-pipeline system. The cold and heat source integrated unit supplies 7°C chilled water that can meet the needs of air conditioning throughout the year, and can also provide a large amount of 55°C hot water for bathing. In addition to the need for a large amount of hot water for bathing, hotel buildings are becoming larger and larger like modern public buildin...

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 which utilizes the principle of energy transfer and comprehensively utilizes it. Background technique [0002] At present, the traditional cold source and heat source of public buildings are mostly the combination of compression refrigeration unit and steam boiler, and the cold source and heat source supply the refrigerant and heat medium required by each functional space in the whole building respectively. This traditional cold source emits considerable waste heat while consuming electric energy to output chilled water, which is discharged to the outside. The same heat source consumes fossil fuels to output steam while discharging high-temperature flue gas and condensed water. It can be seen that the concept of traditional cold source and heat source is always consuming energy and generating wa...
