The utility model discloses an energy-saving heating system for heat pump air conditioning, which comprises a heat pump air conditioning, an ice making air conditioning, a cold and heat exchanger and an ice storage. The cold and heat exchanger is a box with water inside, and is provided with cold water return pipe and hot water return pipe. The two ends of the cold water return pipe are respectively connected with the cold water drain pipe of the heat pump air conditioner and the first inlet pipe. The hot water return pipe is respectively connected with the hot water drain pipe and the second inlet pipe of the ice making air conditioner, and the cold water return pipe and the heat pipe. The water return pipes are not connected and are all located in the box of the cold and heat exchanger; the heat pump air-conditioning also provides heat for the house through the heating pipe; the ice-making air-conditioning also lowers the temperature of the house through the cooling pipe. The heat pump air-conditioning energy-saving heating system in this application uses ice-making air-conditioning and cold and heat exchanger. The heat pump air-conditioning can still work normally under 0 C, and the ice-making air-conditioning can be operated at the same time to achieve the purpose of environmental protection and energy conservation.

热泵空调节能供暖系统
本技术涉及环保及空调
,具体地说,是涉及一种热泵空调节能供暖系统。
技术介绍
热泵型空调器利用结构和单冷型空调器的结构基本相同,它是利用空调在夏季制冷的原理,即空调在夏季时,是室内制冷,室外散热,而在秋冬季制热时,方向同夏季相反,室内制热,室外制冷来达到制暖的目的。它的优点是功效较高,缺点是适用温度范围较小。现有技术中热泵空调供暖时,当室外温度为7℃时热泵制热能力为100%,当环境温度降到0℃时热泵空调制热能力下降18%,当室外温度在0℃以下时热泵空调制热功能就不能正常运行。
技术实现思路
本技术的目的是解决上述技术的不足,提供一种能够使热泵空调在0℃以下仍能正常工作的热泵空调节能供暖系统。为解决上述技术问题,本技术提供了一种热泵空调节能供暖系统,包括热泵空调、制冰空调、冷热交换器和冰库,其中,所述冷热交换器为箱体、内装有水,设有冷水回水管和热水回水管,其中冷水回水管的两端分别与所述热泵空调的冷水排水管、和第一进水管相通,热水回水管分别与所述制冰空调的热水排水管、第二进水管相通,所述冷水回水管与热水回水管不接通、均位于所述冷热交换器的箱体内;所述热泵空调,还通过供热管道为房屋供热,供热管道上设有供热阀;所述制冰空调,还通过供冷管道为房屋降温,供冷管道上设有供冷阀。优选地,所述冰库还连接有水泵。优选地,所述热泵空调的数量至少为1台,当所述热泵空调的数量为大于等于2时、热泵空调为并联设置。优选地,所述制冰空调的数量至少为1台,当所述制冰空调的数量为大于等于2时、制冰空调为并联设置。优选地,所述冷水排水管、热水排水管、供热管道、供冷管道、第一 ...
