Abstract

The invention relates to a heating device and particularly relates to an auxiliary electric heater of a central air-conditioner. The technical scheme includes that the auxiliary electric heater comprises a heating box body, a heating coil, a terminal box, a temperature controller, a temperature measuring device, a water inlet, a pressure reducing valve, a water outlet and a drain outlet, wherein the terminal box is connected to one side of the heating box body, the water inlet and the water outlet are arranged on the heating box body, the drain outlet is arranged at the bottom of the heating box body, the heating coil is fixed inside the heating box body, the heating coil is connected with the terminal box, the temperature controller is arranged inside the terminal box and is connected with the temperature measuring device, and the pressure reducing valve is arranged at the top of the heating box body. The auxiliary electric heater has the advantages that preheating is conducted on an aqueous medium through the auxiliary electric heater of the central air-conditioner, the water temperature is increased, the normal starting and operation of an air conditioning unit can be guaranteed, and the heat supply efficiency and the heat supply effect of a main machine can be improved.

Description

1. Technical field [0001] The invention relates to a heating device, in particular to an auxiliary electric heater for a central air conditioner. 2. Background technology [0002] All the cold water in the existing auxiliary heater needs to be heated and then flow out. There is no separate cold water pipe, and all the water entering the cavity must be heated. When hot water is not used, there will be residual temperature, making the inner cavity of the auxiliary heater Limescale forms. When there are cold water pipes and hot water pipes in the place where the auxiliary heater is used, the cold water pipes should be installed separately. The existing auxiliary heater is not equipped with a pressure reducing valve, which will cause danger at high pressure and high temperature, which will damage the auxiliary heater and cause the electric heating tube of the heater to burn easily. Material, a single heating tube is small in size and has a large surface load. Such a heating tu...
