Heat recovery composite energy system for hospital buildings

Abstract

The invention relates to a heat recovery composite energy system for hospital buildings. The heat recovery composite energy system for the hospital buildings is composed of a GSHP (Ground Source Heat Pump) air conditioning system, a heating water tank, a hot water storage tank, a backwater electromagnetic valve and a control cabinet, all of which are connected circularly and in order, wherein a hot water make-up pump and a hot water circulating pump A are connected between the heating water tank and the hot water storage tank respectively; an inlet water electromagnetic valve is connected between the heating water tank and the control cabinet; the GSHP air conditioning system is a combined system of a partial heat recovery GSHP machine set and a total heat GSHP machine set; the partial heat recovery GSHP machine set is communicated with the heating water tank and is provided with a hot water circulating pump B; the partial heat recovery GSHP machine set and the hot water circulating pump B are connected through the control of the control cabinet; the total heat recovery GSHP machine set is communicated with the heating water tank and is provided with a hot water circulating pump C; the total heat recovery GSHP machine set and the hot water circulating pump are connected through the control of the control cabinet. The heat recovery composite energy system for hospital buildings is conductive to year-round heat balance of a GSHP buried pipe system, is convenient for management and maintenance, and reduces operating cost.

Description

technical field [0001] The invention relates to a heat recovery heating system, in particular to a heat recovery composite energy system for hospital buildings. Background technique [0002] The ground source heat pump air-conditioning system uses the energy of the shallow layer of the ground to store the heat load of the building underground in summer and take it out for use in winter, realizing energy recycling. It is a new device for sustainable energy utilization. For areas and buildings dominated by cooling loads, the total load of buildings in summer is greater than the total load in winter. If the ground source heat pump air conditioning system is used in both winter and summer, the heat emitted to the soil in summer is greater than the heat extracted from the soil in winter. The passage of time will inevitably affect the restoration of the soil temperature field around the buried pipe, resulting in a continuous decline in the COP of the ground source heat pump, which...

Problems solved by technology

1. Increase the power consumption of cooling tower fans and water pumps; 2. Occupy a large area of ​​space; 3. Generate noise; 4. Disadvantages such as a large loss of domestic water consumption

[0003] The solar water heating system is a device that uses solar collectors to collect solar radiation to heat water. However, because of the large demand for hot water in hospital buildings, a large area of ​​solar collectors is required to be arranged on the roof, and a large amount of investment is required. , at the same time, the water production rate cannot be guaranteed due to sunshine, and an electric auxiliary heating system needs to be added, which consumes a lot of electric energy
