Embodiment Construction

[0024] The absorption cooling and heating integrated machine proposed by the present invention is based on the principle of ammonia-salt diffusion absorption refrigeration. It uses ammonia as the refrigerant, salt as the absorbent, hydrogen or helium as the diffusion gas, and its refrigeration temperature can be as low as - 30°C, it can also provide a cooling temperature of 2 to 10°C for air conditioning or refrigeration at the same time as required, and while achieving high and low evaporation temperature refrigeration, it can recover the heat of the steam at the outlet of the generator to provide sanitary hot water. It is a kind of Multi-purpose cooling and heating all-in-one machine. The refrigerant used in this specific embodiment is ammonia-salt, which is a solution composed of sodium thiocyanide (NaSCN) and ammonia. A solution of lithium nitrate (LiNO3) and ammonia may also be used. Because sodium thiocyanate or lithium nitrate is solid at normal temperature, and the bo...

Abstract

The invention relates to an absorption type integrative machine, comprising a high evaporation temperature cooling loop, a low evaporation temperature cooling loop and a heat retriever; the high evaporation temperature cooling loop comprises a generator, a condenser and a first evaporator and a solution heat exchanger; the generator is driven by external heat source, one end of the generator is connected with the condenser, another end is connected with the solution heat exchanger; the heat retriever is in series connection between the generator and the condenser. The absorption type cool-heat integrative machine of technical proposal of the invention, because including two respectively independently cooling loops, the high evaporation temperature cooling loop and the low evaporation temperature cooling loop with different evaporation temperatures, can efficiently use the remaining heat, the waste heat, the solar energy, the gas and the power energy as energy to cool, and at the same time of generating sanitary hot water, can provide refrigeration below zero DEG C, cool storage above zero DEG C and the air-conditioner refrigeration, thus improving the energy consumption efficiency at the same time of protecting the natural environment of earth.

Description

technical field [0001] The invention relates to the technical field of air-conditioning and refrigeration, in particular to an absorption type cooling and heating integrated machine, in particular to an absorption type cooling and heating integrated machine with hot water recovery function and three temperature zones. Background technique [0002] With the improvement of people's awareness of energy saving, refrigeration and air-conditioning products are also paying more and more attention to the heat recovery in the refrigeration process, that is, while realizing the refrigeration or air-conditioning function, the waste heat and waste heat generated in the refrigeration process are recovered and applied as much as possible. , to improve the comprehensive utilization of energy. The existing refrigeration and air-conditioning equipment with heat recovery can be roughly divided into two categories: one is the equipment using electric refrigeration, and the forms of using both ...
