Description
Technical field:
The utility model relates to a kind of control system, but the large-scale water resource heat pump automatic control system of especially a kind of automatic monitoring equipment operational factor, the labor strength that reduces, minimizing operating cost.
Background technology:
Existing water source heat pump system comprises source pump and auxiliary equipment, the structure of source pump is to be provided with compressor, be connected with condenser, evaporimeter between the outlet of compressor and the inlet, the working media of compressor connects by shell side, water by evaporimeter, condenser is then linked to each other by tube side, be connected to evaporimeter pump, condenser pump and magnetic valve, motor-driven valve etc. on tube side respectively, auxiliary equipment then has the water intaking water pump, distributes water pump, small pump (cool cycles water pump), cooling fan and the motor-driven valve that joins with it, magnetic valve etc.Heat process: the tube side entrance and exit of condenser joins by distributing water pump and substation, the tube side entrance and exit of evaporimeter joins by water intaking water pump and heat supply water source, when the working media in the evaporimeter shell side is evaporated to gas, absorb the heat supply water source heat in the evaporimeter tube side, the gas of evaporation is compressed into the HTHP gas by compressor, this HTHP gas is condensed into liquid in the shell side of condenser, emit heat simultaneously, water in the hot-water heating system in the condenser tube side is heated ... circulate with this, heat in the heat supply water source can be offered the substation that needs heat, reach the purpose that heats.Process of refrigerastion can join evaporimeter and heat radiation substation by control magnetic valve, motor-driven valve open and close then in contrast, and condenser and resource of water supply join.Because the restriction of compressor, single-machine capacity is generally little, and source pump heats leaving water temperature between 45～50 ℃, can not reach more than 80 ℃, can not satisfy large area heat supply/cooling requirement, and it is low to have limited its range of application and efficient.Therefore, what large area heat supply/cooling was adopted at present all is the large-scale water resource heat pump that is made of many groups water source heat pump system, except that source pump by the Controlled by Programmable Controller, other auxiliary equipment all need manual monitoring, as according to the needs that heat or freeze, the open and close of control motor-driven valve, magnetic valve are according to heat supply/cooling zone power demand size, start, the shutdown of control source pump; Operating frequency according to control pump variable frequency devices such as the pressure of water, pressure reduction; According to the size of discharge, the open and close amount of the relevant motor-driven valve of control, magnetic valve; According to the temperature of cooling circulating water, the power of control cool cycles water pump (small pump or variable frequency pump) and the rotating speed of cooling fan motor.The monitoring workload is big, labour intensity is high, needs several workmans just can finish monitoring work sometimes, and the operating cost of heat pump is strengthened.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, but a kind of automatic monitoring equipment operational factor is provided, reduces labor strength, reduces the large-scale water resource heat pump automatic control system of operating cost.
Technical solution of the present utility model is: a kind of large-scale water resource heat pump automatic control system, be provided with Programmable Logic Controller, be connected to monitor terminal with Programmable Logic Controller, Programmable Logic Controller joins with source pump controller and pump variable frequency device respectively, also be connected to long-distance monitorng device with Programmable Logic Controller, flow sensor, level sensor, temperature sensor, pressure sensor and pressure sensor join, and long-distance monitorng device is also controlled small pump, magnetic valve and cooling fan motor.
The utility model can be monitored in real time to all devices of large-scale water source heat pump system, comprise the startup by ethernet communication control source pump and stop, according to parameters such as the discharge of being monitored, water pressure, differential water pressures, water levels, control pump variable frequency device, make water pump operation at most economical energy-conservation state, simultaneously can be according to the cooling temperature of circulating water of monitoring, automatically control magnetic valve, motor-driven valve, small pump, cooling fan motor etc., also can control as required motor-driven valve with determine to heat, refrigeration mode.Make large-scale water resource heat pump reach unattended fully automatic operation fully, monitor safe and reliable, but automatic monitoring equipment operational factor, the labor strength that reduces, the operating cost that reduces.
