Energy-saving air conditioner system with double recovery of sensible heat and latent heat

Abstract

The invention discloses an energy-saving air conditioner system with double recovery of sensible heat and latent heat. The energy-saving air conditioner system with double recovery of the sensible heat and the latent heat comprises a compressor, a gas-liquid separator, a four-way valve, a throttling device, an indoor unit heat exchanger, an outdoor unit heat exchanger, a hot water pipeline, a sensible heat recovery device and a latent heat recovery device; the outlet of the compressor, the sensible heat recovery device and a first connector of the four-way valve sequentially communicate with one another through a pipeline; a second connector of the four-way valve, the indoor unit heat exchanger, the throttling device, the outdoor unit heat exchanger and a fourth connector of the four-way valve sequentially communicate with one another; a third connector of the four-way valve, the gas-liquid separator and the inlet of the compressor sequentially communicate with one another; the latentheat recovery device is connected in parallel to the outdoor unit heat exchanger; the hot water pipeline is sequentially connected to the cold side channel of the latent heat recovery device and the cold side channel of the sensible heat recovery device; and a bypass water pipe which is connected in parallel to the latent heat recovery device is connected to the hot water pipeline. By adopting theenergy-saving air conditioner system provided by the invention, latent heat is recovered by utilizing the latent heat recovery device, and the temperature of hot water is further raised through the sensible heat recovery device, so that the effluent temperature of the hot water is raised, and the exhaust temperature of the compressor is lowered to the maximum.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning systems, and in particular relates to an energy-saving air-conditioning system with double recovery of sensible heat and latent heat. Background technique [0002] According to statistics, the energy consumption of air conditioners and hot water equipment in my country accounts for 55% of the total energy consumption of public buildings. It is estimated that by 2020, the peak load of air conditioners in summer will be equivalent to the full load capacity of 10 Three Gorges Power Stations, and the power consumption is huge. [0003] With the rapid development of my country's economy and the prosperity of urban commerce, the number of large public buildings and urban complexes is increasing, and the scale is becoming larger and larger. At present, most of the urban complexes are hotels, restaurants, entertainment places (bathing centers, saunas, etc.), high-end apartments, swimming pools, s...

AI Technical Summary

Problems solved by technology

At present, most of the urban complexes are hotels, restaurants, entertainment places (bathing centers, saunas, etc.), high-end apartments, swimming pools, supermarkets, shopping centers, office buildings, etc. The energy consumption of large urban complexes is getting higher and higher. All places need a lot of hot water and cold water for air conditioning and refrigeration. According to the traditional method, the cooling and heating supply are generally set independently. During the cooling process, a large amount of condensation heat generated is discharged into the atmosphere, resulting in energy loss. and serious environmental pollution, and at the same time, boilers are used to produce a large amount of hot water; this energy utilization method does not consider the problems of energy complementarity and cascade utilization, and the energy consumption is high

[0004] The most energy-consuming aspects of large-scale urban complexes are: first, the production of high-temperature hot water generally uses electric energy or gas-fired boilers, which consume a lot of energy and generate a lot of waste gas, polluting the environment; second, the use of refrigerant water for air conditioning Production work generally uses chillers for refrigeration, which consumes a lot of energy and produces a lot of waste heat, polluting the environment
