Description

用于空气源热泵热水机组的气体压缩装置
技术领域
本实用新型涉及空气源热泵热水机组技术领域,尤其涉及一种可将低温低压的制冷工质气体压缩变成高温高压的制冷工质气体的装置。
背景技术
空气源热泵热水机组在夏季运行时,由于室外环境温度较高,压缩机的吸气压力高,机组的制热量大,而夏季用户需要的热水量却较冬季少,造成压缩机压缩能力的闲置;在冬季运行时,由于室外环境温度较低,压缩机的吸气压力低,机组的制热量小,而冬季用户需要的热水量却较夏季多,此时压缩机的压缩能力又出现不能满足用户需求的问题。为解决这一矛盾,普通的空气源热泵热水机组通常采用另外增加电辅助加热器的方式,即在冬季机组制热量不足时,通过开启电辅助加热器的办法来解决。但电辅助加热器效率低,浪费能源,对用户来说也不经济。
实用新型内容
本实用新型所要解决的技术问题是:提供一种用于空气源热泵热水机组的气体压缩装置,以解决空气源热泵热水机组在夏季运行时,用户需要的热水量相对少,而机组的制热量却相对大,造成制热能力过剩;在冬季运行时,用户需要的热水量相对多,而机组的制热量却相对小,造成制热能力不足的问题。
为解决上述技术问题,本实用新型的技术方案是:用于空气源热泵热水机组的气体压缩装置,其至少由两台压缩机构成,所述这些压缩机的吸气管和排气管分别并联;它还包括可探测环境温度的温度传感器,和分别与温度传感器以及每一台压缩机电连接的控制器,所述控制器设有可将温度传感器探测到的温度信号与温度设定值进行比较并根据比较结果使相应的压缩机进入开启状态的控制电路。
作为一种改进,所述这些压缩机中的一台为变频压缩机。
由于采用了上述技术方案,该热水机组在夏季使用时,如果环境温度高于温度设定值,控制器的控制电路将温度传感器探测到的温度信号与温度设定值进行比较,并根据比较结果使台数相对少的压缩机进入开启状态,从而减小了整个气体压缩装置的压缩能力,适应了用户夏季用热水少的需求;在冬季使用时,如果环境温度低于温度设定值,控制器的控制电路将根据比较结果,使台数相对多的压缩机进入开启状态,从而增大了整个气体压缩装置的压缩能力,适应了用户冬季用热多的需求。它不需要额外增加电辅助加热器,热效率高,而且降低了用户的使用成本。
由于所述这些压缩机中的一台为变频压缩机,当该变频压缩机被设为工作机时,它可以根据用户需要热量的多少,通过调整变频压缩机的供电频率,改变所述变频压缩机的电机转速,从而调整变频压缩机的压缩能力,使整个机组的运行更加经济,进一步降低用户的使用成本。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是本实用新型实施例的控制原理图;
图2是本实用新型实施例中压缩机的管路连接示意图。
具体实施方式
图2示出了本实用新型实施例中压缩机的管路连接示意图,包括第一压缩机11和第二压缩机12,这两台压缩机的吸气管和排气管分别并联。第一压缩机11和第二压缩机12中的一台为变频压缩机。
图1示出了本实用新型实施例的控制原理图,它还包括可探测环境温度的温度传感器3,和分别与温度传感器3、每一台压缩机电连接的控制器2,所述控制器2设有可将温度传感器探测到的温度信号与温度设定值进行比较并根据比较结果使相应的压缩机进入开启状态的控制电路,该控制电路的具体结构是本领域的技术人员能够很容易想到的。
使用本实用新型的空气源热泵热水机组在夏季使用时,如果环境温度高于温度设定值,控制器2的控制电路将温度传感器3探测到的温度信号与温度设定值进行比较,并根据比较结果使台数相对少的压缩机进入开启状态,从而减小了整个气体压缩装置的压缩能力,适应了用户夏季用热水少的需求;在冬季使用时,如果环境温度低于温度设定值,控制器2的控制电路将根据比较结果,使台数相对多的压缩机进入开启状态,从而增大了整个气体压缩装置的压缩能力,适应了用户冬季用热多的需求。它不需要额外增加电辅助加热器,热效率高,而且降低了用户的使用成本。
本实用新型不局限于上述实施方式,例如压缩机可以全部采用普通的定频压缩机,根据需要压缩机也可以设为多台。
