Embodiment 1

[0015] Embodiment 1: see figure 1 In this embodiment, a heat pump system for preparing hot water by using waste heat in an elevator machine room, the air source heat pump 1 is a commercially available RB-51K air source heat pump with a power of 50Kw produced in the United States. Water tank 3 adopts commercially available common SX-60 type heating water tank. Pump 2 is a commercially available JYB-40 pressurized pump with a power of 3Kw. Above-mentioned air source heat pump 1, pump 2 and water tank 3 according to above-mentioned technical scheme and figure 1 The connection in the shown connection mode becomes the finished product of the present invention. When using this heat pump system to produce hot water by utilizing the waste heat of the elevator machine room to produce hot water, the above-mentioned system device can be arranged in the elevator machine room of the construction unit. During operation, fill the water tank 3 with water; start the pump 2; then start the a...

Embodiment 2

[0017] Example 2: see figure 1 In this embodiment, a heat pump system for preparing hot water by utilizing waste heat in an elevator machine room, the air source heat pump 1 is a commercially available RB-52 air source heat pump with a power of 100Kw produced in the United States, and the remaining components, connection methods and usage methods are the same Example 1.

[0018] A heat pump system of the present invention that utilizes the waste heat of the elevator machine room to prepare hot water, which is composed of the above, has been trial-produced and put into commercial hotels for trial use. It has been proved that the effect is good, the operation is normal, and the purpose of energy saving and environmental protection has been achieved. It has great value in energy strategy. Market prospects.

Abstract

A heat pump system is provided for heating water by using waste heat from an elevator machine room, comprising an air source heat pump 1, a pump 2 and a water tank 3, wherein the input of the pump 2 is connected with the outlet of the water tank 3 via a pipeline, the output of the pump 2 is connected with the inlet of the air source heat pump 1 via a pipeline, and the output of the air source heat pump 1 is connected with the inlet of the water tank 3 via a pipeline. The heat pump system is arranged inside the elevator machine room when in operation, to heat water by using the water heat of the elevator machine room. The invention has the advantages of reduced energy consumption (by 70% above), no frost formation in winter, stable yield, multiple functions in one machine, wide application range, resource utilization and good market prospect.

Description

technical field [0001] The invention relates to a heat supply system, in particular to a heat pump system for preparing hot water by utilizing waste heat discharged from an elevator machine room of a building. Background technique [0002] With the development of society, many star hotels and restaurants have sprung up. Most of the sanitary hot water in these hotels is provided by oil-fired boilers, natural gas boilers, electric boilers or coal boilers, which is not only inefficient, but also seriously polluting, which is contrary to creating an energy-saving and environmentally friendly social environment. In fact, as we all know, there is a large amount of waste heat discharged from the elevator machine room supporting the hotel, which has not been rationally developed and utilized so far, resulting in a large amount of waste of heat energy. At the same time, in summer, the temperature of the machine room is too high. Contents of the invention [0003] The technical pro...
