Abstract

The invention discloses a huge-temperature-difference single tube long distance conveying chilled water storage and cooling system. The system comprises a water pump, a first water source heat pump, a delivery pump, a long-distance conveying single pipe, a condition transformation valve, a heat exchanger, a cold storage tank, a second water source heat pump, a cold discharge pump, a cold storage pump and an air conditioning terminal, wherein the condition transformation valve is provided with a first port, a second port, a third port, a first electric valve and a second electric valve, the first port, the second port and the third port are mutually communicated, the first electric valve is arranged between the first port and the second port, the first electric valve and the second electric valve are arranged between the first port and the third port, and the second electric valve is arranged between the second port and the third port. The huge-temperature-difference single tube long distance conveying chilled water storage and cooling system provided by the invention fully utilizes surface water resources and terrestrial heat, has the advantages of low initial cost, energy saving, environment friendliness and the like, and can be used over a long distance.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a single-tube long-distance transport water cold storage system with super large temperature difference. Background technique [0002] With the improvement of people's awareness of energy conservation, more and more technicians consider applying renewable resources such as geothermal energy, wind energy, and solar energy to daily air-conditioning systems, among which surface water source heat pump technology has been used under certain conditions. However, users in places far away from abundant surface water lack energy-efficiency ratio and cost-effectiveness ratio in terms of cooling transmission efficiency and initial investment of air-conditioning systems, making it difficult to reuse the cold and heat of surface water. How to make more extensive use of the abundant surface water heat energy, and carry out long-distance transmission, and at the same time save ...
