Anti-freezing secondary refrigerant recycling device for central air-conditioning system of energy tower

Abstract

The invention discloses an anti-freezing secondary refrigerant recycling device for a central air-conditioning system of an energy tower. The anti-freezing secondary refrigerant recycling device comprises at least one liquid storage tank, an automatic exhaust valve is arranged on each liquid storage tank, a first port and a second port are respectively arranged on each liquid storage tank, a solution concentration meter is arranged on each liquid storage tank, a blow-down valve is arranged at the bottom of each liquid storage tank, the liquid storage tanks communicate with a central air conditioner cooling recovery pipe through a recovery pipeline, the liquid storage tanks communicate with a central air conditioner cooling supply pipe through a supply pipeline, and a solution supply pump is arranged on the supply pipeline. According to the anti-freezing secondary refrigerant recycling device for the central air-conditioning system of the energy tower, the anti-freezing liquid recycling difficulty can be greatly simplified, the anti-freezing liquid recycling quality can be improved, and the problems that the concentration of the anti-freezing liquid is reduced due to moisture absorption in the storage process and the like are effectively prevented. Recovery and supply work of the anti-freezing liquid is simplified, and intelligence and convenience of personnel operation are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a recovery and reuse device for an antifreeze carrier refrigerant used in an energy tower central air conditioning system. Background technique [0002] In the middle and lower reaches of the Yangtze River and other areas with hot summer and cold winter, the basic form of central air conditioning in civil buildings is mostly "water-cooled unit + gas (oil) boiler", but two sets of energy systems, cooling and heating, need to be set up in this mode. Therefore, in response to this situation in the market, a system form of energy tower central air conditioning has been developed. The system host adopts a water source heat pump unit, and the energy tower equipment is equivalent to the ground source side or water source side of the traditional water source heat pump system. The energy tower adopts a closed system, which is responsible for taking away the heat generated...

AI Technical Summary

Problems solved by technology

Although this solution solves the freezing problem of the circulating fluid in winter, the problem of high viscosity relative to the water medium and poor heat transfer effect is more prominent during summer operation. Generally, it is necessary to replace the antifreeze circulating fluid with water medium

[0004] In the absence of special recycling equipment, the work of replacing antifreeze every year is very cumbersome, and the replaced antifreeze is often discarded directly, making it difficult to reuse, resulting in an increase in energy management costs
