A Space Radiation Cooler as an Auxiliary Cooling Source and Its Heat Transfer Modeling Method

Abstract

The invention discloses a space radiation refrigerator used as an auxiliary cold source and a heat transfer modeling method. The space radiation refrigerator comprises a metal frame which is provided with one or more radiation refrigerator modules, each radiation refrigerator module comprises two zinc-plated steel plates, and a gap for flowing of cooling water is formed between every two zinc-plated steel plates; the two ends of each zinc-plated steel plate in the length direction are communicated with a cooling water separator and a cooling water collector respectively, the cooling water separator is communicated with a cooling water inlet, and the cooling water collector is communicated with a cooling water outlet; the two ends of each zinc-plated steel plate in the width direction are connected. The space radiation refrigerator can be connected with other stable cold sources of a water source heat pump system in series or parallel for use under the optimal weather condition, and cold energy is provided for the heat pump system together.

Description

technical field [0001] The invention relates to a space radiation refrigerator as an auxiliary cold source and a heat transfer modeling method, belonging to the technical fields of building environment and equipment engineering, building thermal environment and refrigeration engineering. Background technique [0002] In recent years, ground source heat pump technology using renewable shallow geothermal energy has developed rapidly in the field of building air conditioning. Among them, the buried pipe ground source heat pump technology flows through the closed underground buried pipe through the circulating fluid, which protects the precious groundwater resources while realizing efficient heat exchange. At present, many international organizations and governments are promoting the application of buried pipe ground source heat pump technology as a way to save energy and reduce CO2. 2 An important means to discharge and improve environmental problems. Buried pipe ground sourc...

Problems solved by technology

Secondly, the cooling efficiency of the space radiation cooler is greatly affected by the relative humidity of the outdoor air, the thickness of the cloud layer in the sky, and the cleanliness of the air, and the cooling capacity is not stable.

Thirdly, the energy flow density of the space radiation cooler is not high, and the cooling power per unit area is not large, so it needs to occupy a large building roof area
