Problems solved by technology

However, the equipment system of this method is relatively complicated and occupies a large area.
Sometimes the pressure provided by the heat source is also difficult to meet the pressure difference requirements of the usual heat exchanger, which in turn affects the flow rate of the primary heat medium, making it difficult to achieve good results
The water mixer can also achieve cooling and heating, but it needs the outdoor pipe network to provide a large pressure difference between the supply and return water, which is difficult to achieve under normal use conditions and often affects its use range

Abstract

The present invention is building cooling and heating apparatus, and belongs to the field of heating, ventilating and air conditioning technology. The building cooling and heating apparatus has increased heat medium flow rate controlling valve, by-pass pipe and its control parts, heat medium mixing pump in the by-pass loop, compensation controller and frequency varying control box. The present invention can provide local cooling and heating mode, enhanced regulating function, static pressure cutting and energy saving running.

Description

technical field [0001] The invention belongs to the technical field of heating, ventilating and air-conditioning, and mainly relates to the structural improvement of the piping of the heating system when the temperature of the heating medium of the heating source is inconsistent with the working temperature of the user. Background technique [0002] As we all know, when the hot water temperature requirement of the heat user's indoor heat transmission and distribution system is lower than that provided by the outdoor heat source, for example, the boiler room provides hot water with the standard parameter of 95 / 70°C, while individual users need 50 / 40°C When building ground radiant heating, the usual method is to use various forms of surface heat exchangers to reduce the temperature of the secondary heat medium to the water temperature required by the heat user, which can meet the specific requirements of the user. However, the equipment system of this method is relatively comp...
