Problems solved by technology
However, under the condition of ultra-low temperature outdoors, the heating capacity attenuation is very serious, and it cannot even start and run normally. In the cold regions of northern my country, it can only be used in transitional seasons. In the case of outdoor ultra-high temperature or the cooling tower is very dirty, the unit cannot start and run normally

The invention relates to a central air conditioning system using a three-way set of four-pipe control superelevation and low temperature heat pumps as well as hot water. The three-way central air conditioning system is composed of a three-way set of the superelevation and low temperature heat pumps as well as the hot water, an evaporative cooling tower, an indoor heat exchanger, a condensation pump, a freezing pump, a hot water circulating pump, and a hot water incubator, wherein the three-way set of the superelevation and low temperature heat pumps and the hot water is composed of a compressor, a hot water heat exchanger, a condenser, a shoot intercooler, a filter, an electronic expansion valve, an evaporator, and a turbocharger. The three-way central air conditioning system using the four-pipe control superelevation, the low temperature heat pump and the hot water provided by the invention can normally work and operate under the outdoor ultra-temperature and ultra low temperature working condition and has the effects of good refrigeration, heating generation, and hot water generation; and the central air conditioning system provided by the invention has the advantages of less equipment investment, energy conservation and emission reduction, and is stable and reliable in operation.
Description
1. Technical field [0001] The invention relates to the field of a four-pipe heat pump and hot water three-purpose central air-conditioning system, in particular to a four-pipe ultra-high and low-temperature system with good cooling, heating, and hot water effects under outdoor ultra-high temperature and ultra-low temperature conditions. Heat pump, hot water three-purpose central air-conditioning system. 2. Background technology [0002] In the prior art, the invention patent of application number 200810070702.1 discloses a four-pipe heat pump and hot water three-purpose central air-conditioning system. This three-purpose central air-conditioning system can provide four-pipe refrigerant, which can supply heat refrigerant throughout the year. Cold load refrigerant, domestic hot water, flexible adjustment of room temperature, providing domestic hot water around the clock. However, under the condition of ultra-low temperature outdoors, the heating capacity attenuation is very s...
