Embodiment

[0024] The following is based on figure 1 , further describe the operation control method of the present invention:

[0025] When the outdoor temperature is high in summer and the cooling load of the air conditioner is large, the water-cooled chiller unit and the water ground source heat pump unit are connected in parallel for cooling. At this time, the pre-cooling (heated) water switching valve 5 and the cooled (pre-heating) water switching valve are closed. 6. Open the remaining valves; the cooling water on the condenser 1 side of the water-cooled chiller passes through the water outlet of the condenser 1 of the water-cooled chiller, flows through the condenser outlet switching valve 3, and flows from the condenser outlet pipe 9 to the cooling device for cooling. The cooled cooling water enters the condenser 1 of the water-cooled chiller unit from the condenser water inlet pipe 10 through the inlet switching valve 4; the chilled water on the evaporator 2 side of the water-gr...

Abstract

The invention discloses combined heat recovery equipment and a valve control method thereof. The combined heat recovery equipment comprises a water-cooling water chilling unit condenser and a ground water heat pump unit evaporator, wherein changeover valves are arranged on inlet and outlet pipelines of the water-cooling water chilling unit condenser and the ground water heat pump unit evaporator; a communicating pipeline between a water outlet of the water-cooling water chilling unit condenser and the water outlet changeover valve is led to between a water inlet of the ground water heat pump unit evaporator and the water inlet changeover valve; a communicating pipeline between a water inlet of the water-cooling water chilling unit condenser and the water inlet changeover valve is led to between a water outlet of the ground water heat pump unit evaporator and the water outlet changeover valve; and changeover valves are arranged on the communicating pipelines. According to the combined heat recovery equipment and the valve control method, the water-cooling water chilling unit condenser and the ground water heat pump unit evaporator are controlled; a heat exchange temperature difference between the water-cooling water chilling unit condenser and the ground water heat pump unit evaporator is reduced; the working energy consumption of a refrigeration compressor is reduced effectively; and an electricity resource is saved greatly.

Description

technical field [0001] The invention belongs to the field of air-conditioning cold and heat sources, and relates to an air-conditioning heat recovery device, in particular to a heat recovery device and a valve control method for simultaneously providing cold and heat sources. Background technique [0002] With the development of society and the improvement of people's living standards, air-conditioning and refrigeration are required throughout the year for data computer rooms, some precision instruments, pharmaceuticals and health care products. Office, residential, commercial and most process rooms are preheated in winter. How to effectively use the waste heat and reduce the energy consumption of air conditioning, cooling and heating is the focus of energy saving and consumption reduction in China and even in the world. [0003] In order to meet the needs of social development and national energy-saving policies, there are a wide variety of energy-saving and heat recovery p...
