Recycling and recycling device for antifreeze refrigerant used in energy tower central air conditioning system

Abstract

The invention discloses a recovery and reuse device for an antifreeze refrigerant used in a central air conditioning system of an energy tower, comprising at least one liquid storage tank, an automatic exhaust valve is arranged on the liquid storage tank, and an automatic exhaust valve is arranged on the liquid storage tank. A first interface and a second interface are respectively provided, the liquid storage tank is provided with a solution concentration meter, the bottom of the liquid storage tank is provided with a drain valve, and the liquid storage tank is connected with the central air conditioning cooling recovery pipe through a recovery pipeline The liquid storage tank is communicated with the central air-conditioning cooling supply pipe through a supply pipe, and a solution supply pump is arranged on the supply pipe. The invention can greatly simplify the difficulty of recovering the antifreeze, improve the quality of the recovery of the antifreeze, and effectively prevent the problems such as the reduction of the concentration of the antifreeze during storage and moisture absorption. The recovery and supply of antifreeze is simplified, and the intelligence and convenience of personnel operations 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 a traditional water source heat pump system. The energy tower adopts a closed system, which is responsible for taking away the heat generated b...

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
