Embodiment 1

[0022] The technical solutions of the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0023] Such as figure 1 A cold and hot central air-conditioning pump circulation system is shown, and the process is briefly described as follows:

[0024] In fact, the hot and cold air conditioner is to disconnect the 18, 19 of the indoor water circulation pump A2 output pipe of the indoor circulation system of the single-refrigeration central air conditioner and join the hot water boiler 6, and control it through the valves 8, 9, 10 to solve the switch between winter and summer. For heat demand, the core working composition of the central air conditioner for cooling in summer is mainly the modular refrigeration unit 5, the valves 8 and 9 are opened and the valve 10 is closed. The modular refrigeration unit 5 includes multiple parallel compressors 51, condensers 52, evaporation The compressor 53 and the el...

Abstract

The invention discloses a cooling and heating central air-conditioning pump circulation system, comprising a circulating water pool, the circulating water pool is connected to the cooling circulation pump and the condenser in the modular refrigeration unit through the first pipeline, and the condenser is connected to the cooling water tower through the second pipeline, and the cooling water The tower is connected to the circulating pool; the modular refrigeration unit is equipped with an evaporator and several compressors; one end of the evaporator is connected to an indoor water circulation pump, and the indoor water circulation pump is connected to the water heater through the third pipe, and the water heater is connected to the water heater through the fourth pipe. The fan coil unit is connected to the other end of the evaporator and the indoor water circulation pump; the fan coil units are arranged in parallel. The invention is convenient to use, simple in structure, uniform in heat exchange and heat dissipation, well adapted to people's needs and easy to disassemble.

Description

technical field [0001] The invention belongs to the field of temperature control, and in particular relates to a cold and hot central air-conditioning pump circulation system. Background technique [0002] The central air-conditioning system generally consists of a cold and heat source system and an air-conditioning system. Generally, the principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides heat for the air conditioning system to offset the cooling load of the indoor environment. The cooling and heating system is a crucial part of the central air-conditioning system. Its type, operation mode, and structural form directly affect the economy, efficiency, and rationality of the central air-conditioning system in operation. [0003] The heat transfer and heat dissipation of the existing central air-conditioning system are not ...
