Problems solved by technology

[0003] The current closed cooling tower keeps the coils of the closed cooling tower from freezing in winter by continuously adding antifreeze such as ethylene glycol. The amount of antifreeze is difficult to control, resulting in the fact that the heating of the cooling tower cannot be realized

Embodiment Construction

[0011] There are two modes:

[0012] In cooling mode, the heat pump host sends cooling demand and start-up signals to the closed cooling tower control module through the host control module, and the latter controls the external circulation pump, internal circulation pump and fan of the closed cooling tower to start. The function of the cooling tower, that is, the spray cooling function, cools the water in the air-cooled coil heat exchanger, and then cools the water in the water-refrigerant condenser through the built-in circulation pump, thereby cooling the latter's refrigerant.

[0013] In heating mode, the heat pump host sends heating demand and start-up signals to the closed cooling tower control module through the host control module, and the latter controls the internal circulation pump and fan of the closed cooling tower to start. The cooling tower fan exchanges heat with the air-cooled coil heat exchanger and heats the water-ethylene glycol solution in it, and then heat...

Abstract

The invention provides a split type water source heat pump system. The split type water source heat pump system comprises a closed type cooling tower (1), at least one heat pump host (2), a closed type cooling tower control module (3) and at least one host control module (4); and the host control module (4) is composed of a corresponding refrigerant pipe and a corresponding communication line. The aim of water cooling of a water source heat pump unit is achieved, heating in winter can be achieved, the aim of defrosting of the closed type cooling tower (1) is achieved, and simple running control over the system can be efficiently achieved with the high reliability.

Description

technical field [0001] This patent relates to a water source heat pump system. Background technique [0002] In the existing HVAC system, the tower used can only transmit the waste heat generated by the system to the air, so it is called a cooling tower or a heat dissipation tower; in the season of heating in winter, auxiliary heating equipment or dry tower must be used to realise. As we all know, the use of auxiliary heating equipment, such as oil-fired gas boilers and electric heating, consumes more energy, and the efficiency of the actual operating system is low; and the use of dry towers, due to the drop in air temperature when absorbing sensible heat in the air. The water vapor in it condenses into water droplets on the surface of the coil, and frost will form after a long time, so the system must take a long time to reverse the heat pump to defrost. When the system is reversed, no heat can be generated. Therefore, the efficiency It is also lower and its life is short...
